C3B – Five Years in the Making

The Center for Bioelectronics, Biosensors and Biochips was officially dedicated in October, 2000 as a center for research and development of engineered biosystems.  In less than five years, C3B has established a well deserved reputation for innovative and multidisciplinary research in the VCU School of Engineering.  C3B’s collaborative culture fosters a team-oriented research approach that has been exemplified in projects with the School of Medicine and the Department of Chemistry in the College of Humanities and Science.

Exciting research is being conducted in the Biosensors and Biochip labs.  This special issue of the C3B Reporter highlights the key projects, updates the news on the 4P’s (publications, presentations, proposals and patents), and introduces the researchers who are making it happen.  Plans are in place to continuously improve C3B’s relationships with its constituencies, and to expand its base of support.  At the leadership helm of the C3B is Dr. Anthony Guiseppi-Elie who was quoted in the Richmond Times-Dispatch, "I have the best job in the world."

VCU's 'global player'

A professor in two departments, he founded biotechnology company and is widely known for research…

RICHMOND TIMES-DISPATCH, November 2, 2004

“NanoBiotechnology: What’s All the Fuss about Small Stuff” was the subject of Professor Guiseppi-Elie’s keynote address at the Virginia Space Grant Consortium Scholars and Fellows Luncheon.  The luncheon, hosted by Virginia Tech President Steger at the Newport News Omni Hotel on April 1, 2005, celebrated the accomplishments of the Consortium’s graduating Fellows and Scholars.

Guiseppi-Elie, the man and his mission, to be profiled in the June 2005 issue of BioTechniques -- look out for this issue.

Text Box:  “We are moving into the animal testing phase of the implantable biosensor for glucose and lactate monitoring,” said Dr. Sean Brahim, Research Associate and Lab Director. In this high profile Department of Defense funded project, the next step is working with the School of Medicine to test the feasibility of the biosensors by implanting them into lab animals. The in vivo biosensor for the continuous monitoring of tissue glucose and lactate has important applications in risk stratification in trauma care, in chronic diabetes care and is being developed for military battlefield management of wounded soldiers. Other key projects in the Biosensors Lab include the development of an impedimetric biosensor for the monitoring of urea for dialysis management, the development of novel biomimetic and responsive (smart) polymeric hydrogels and the application of single walled carbon nanotubes for reagentless nanobiosensors.

Text Box:  G. Scott Taylor, Ph.D. (engineering) student, Acting Lab Director, “We have a state-of-the-art laboratory that is well equipped to conduct our gene expression and biochip experiments.”  (Note: see equipment acquisition)  The Biochips Lab has a Class 1000 clean room for producing DNA microarrays, along with the instruments necessary for conducting gene expression and DNA hybridization experiments. Current projects with Pathology (Dr. Carleton Garrett) involve examining brain, ovarian and breast tumor samples; with Neurosurgery (Dr. William Broaddus) involve the study of the genetic anatomy of primary brain tumors, and with Chemistry (Dr. Nick Farrell), a study of platinum-based drug candidates for their physicochemical interactions with DNA.

Text Box:  The Signal Processing Laboratory is a virtual laboratory vested with the responsibility for applying appropriate SP tools and techniques to all of the biosystems metrology tools under development at the C3B. “Signal processing and informatics are central to our mission, and, is one of the underpinning disciplines to our Center”, said Center Director, Anthony Guiseppi-Elie. We were saddened by the recent departure of Dr. Arvind Srivastava, the former director of this laboratory, who has moved to join the nanotechnology center, NUANCE, at Northwestern University, Evanston, Illinois. "We now have an opportunity to redefine this position in view of the broad and varied undertakings at the C3B" said Guiseppi-Elie. This laboratory will now be called the Signal Processing and Informatics Laboratory and will embrace our bioinformatics tools and platforms as well as our traditional signal processing capabilities. We will be looking to appoint a suitable postdoctoral candidate with breath of experience and knowledge in SP and bioinformatics.

Two important papers on achieving biological "stealth":

In two landmark papers, Prof. Guiseppi-Elie and his students describe the molecular engineering of biomimetic synthetic polymers that are capable of achieving biological stealth when implanted into the body of rats. That is, fooling the body to believe that an implanted device or material is indeed part of native tissue. In their recently publish paper that appeared in Biomaterials (Molecularly Engineered p(HEMA)-based hydrogels for implant biochip biocompatibility, Biomaterials (2005) 26: 4767-4778) graduate student Sheena Abraham, research associate Dr. Sean Brahim and Prof. Anthony Guiseppi-Elie, in collaboration with Prof. Kazuhiko Ishihara, The University of Tokyo, Japan, describe the details of design and synthesis of biomimetic materials based on the use of phosphorylcholine and polyethylene glycol. Phosphorylcholine (PC) is the active head group of the outer leaflet of the membrane bi-layer of most cells. The chemistry of this group was imparted to synthetic hydrogels, commonly used to make plastic contact lenses. In this seminal paper, the molecularly engineered hydrogels were demonstrated to resist common ECM protein adsorption while remaining non-cytotoxic to human epithelial and fibroblast cell cultures. These materials therefore exhibit the much desired and sought-after characteristics for implant material coatings. In another related manuscript submitted to the journal Langmuir, (Molecularly Engineered p(HEMA)-based Hydrogels: Hydration, Protein Adsorption and Cytotoxicity), the details and kinetics of protein adsorption are described and modeled in relation to the extent of hydration of these hydrogel materials. This research is supported by a grant (PR023081) from the US Department of Defense (DoDPRMRP).

 

Carbon nanotubes enable direct nano-biosensors for Enzymes and Proteins - NanoBiotechnology paper:

In 2001 Prof. Guiseppi-Elie and postdoctoral fellow, Chenghong Lei , along with University of Texas collaborator, Raymond Baughman published a paper on the use of single-walled carbon nanotubes as substrates for direct electron transfer to the flavin centers of oxidoreductase enzymes. This paper has  achieved notable citations that place it in the top 1% of papers in the field of biosensors. This year Prof. Guiseppi-Elie and research associate Dr. Sean Brahim, again with University of Texas collaborator, Raymond Baughman, with contributions from Case Western Reserve University Engineering Professor, Dr. Gary Wnek, have submitted yet another paper, “Carbon Nanotube Modified Electrodes for the Direct Bioelectrochemistry of Pseudoazurin”, extending this work to the bioelectrochemistry of the metalloprotein pseudoazurin. The latter paper has now been accepted for publication in the inaugural issue of the recently formed journal, NanoBiotechnology, In both these papers the authors demonstrate how these novel carbonaceous materials can be made to shuttle electrons to and from the redox centers of these enzymes, thereby reducing the dependence on mediators such as oxygen and other small redox molecules.

 

Design of a Subcutaneous Implantable Biochip for Monitoring of Glucose and Lactate:

In a similarly titled manuscript accepted for publication in IEEE Sensors Journal (2005), Prof. Guiseppi-Elie and C3B researchers Dr. Sean Brahim and Gymama Slaughter, in collaboration with VCURES Associate Director, Dr. Kevin Ward, describe the design and fabrication of a miniature (2 mm x 4 mm) electrode coated with a thin, sensing membrane that responds selectively to both glucose and lactate. The impetus for this research comes from the fact that at present there is no clinically reliable in vivo biosensor that can be used for accurate, continuous, long-term sensing (> 6 months) and reporting of important physiologic metabolites such as glucose and lactate. The need for such a device is absolutely critical for the successful development of truly ‘closed-loop’ systems for treating epidemics such as diabetes and also in combat and civilian casualty care. The electrode fabrication process includes standard microlithographic techniques The biorecognition layer of the working electrodes was fabricated from an ca. 1.0 mm thick composite membrane of principally tetraethylene glycol (TEGDA) cross-linked poly(2-hydroxyethyl methacrylate) that also contained a derivatized polypyrrole monomer and a biomimetic methacrylate component with pendant phosphorylcholine groups. These two additional monomer components were introduced to provide interference screening and in vivo biocompatibility respectively; two major issues that have plagued the successful development of implantable biosensors in the past. Analyte specificity was achieved by immobilizing the appropriate enzyme(s) within the hydrogel membranes. In vitro analytical characterization of the biochip has demonstrated good linear dynamic response ranges, sensitivities, and response times towards both glucose and lactate in simulated physiologic media. In vivo studies in rats are currently in progress. This work is supported by a grant (PR023081) from the US Department of Defense (DoDPRMRP).

 

Two important papers on robust engineering of DNA Microarrays for clinical applications:

In two recently published papers, Prof. Guiseppi-Elie and his students along with VCU Medical Center collaborators describe the design and evaluation of a 20,000 spot human oligonucleotide microarray. The first of these papers address the selection of immobilization chemistries for the attachment of oligonucleotide sequences to DNA microarrays. [Scott Taylor1, Stephanie Smith1, Brad Windle2, and Anthony Guiseppi-Elie1,3,* (2003) Impact of surface chemistry and blocking strategies on DNA microarrays, Nucleic Acids Research Vol. 31,  No. 16]. The second paper investigates and reports on the use of experimental design techniques to evaluate the quality control and assurance impact of potentially variable factors on gene expression results derived from the oligonucleotide microarray. [Scott Taylor1 Kellie J. Archer2, and Anthony Guiseppi-Elie1,3,4,* (Submitted) A Factorial Study of the Influence of Production and Protocol Variables on Gene Expression Data From Spotted Oligonucleotide Microarrays Biotechniques (submitted). Both papers are aimed at designing developing clinically hardened microarray technology

In this special issue, C3B Reporter interviewed two of the researchers to share their views and experiences.

Text Box:  Vandana Gupta

B.S., Biomedical Engineering, 
Minors in Electrical Engineering and Mathematics, Virginia Commonwealth University, 2003

C3B Reporter:  Vandana, can you describe your role in the C3B?

Vandana:  I joined C3B as a Graduate Research Assistant in August, 2003, when I started my M.S. in Engineering program here at VCU.  The major project that I have been managing is related to my thesis, “Design, Development and Performance Evaluation of an Impedimetric Biosensor for Urea.”

C3B Reporter:  Your thesis project sounds very challenging.  How did you prepare for this assignment?

Vandana:  As an undergraduate, I studied biomedical engineering along with electrical engineering (signal processing) so I have a good “textbook” understanding of the research problem.  Even though I lacked laboratory research experience when I first joined C3B, Dr. Guiseppi-Elie (advisor) and other researchers have been very supportive in developing my hands-on research skills.

C3B Reporter:  You will be joining Infineon Technologies this summer after graduation.  What will you be doing, and was your C3B experience helpful in getting this job offer?

Vandana:  I will be starting my career at Infineon as a Lithography Process Engineer in their Richmond, VA semiconductor manufacturing plant.  My C3B experience in learning how to use sophisticated instruments for tests and measurements could have played a role in differentiating me from other job candidates.

C3B Reporter:  What did you enjoy most about your C3B experience?

Vandana:  It is the people and the culture that made my C3B experience very rewarding.  The facilities and tools also contributed to a research environment that is state-of-the-art compared to other university labs.  Dr. G. made sure that we were well equipped to conduct our research.

C3B Reporter:  What advice can you offer to the new graduate research assistants?

Vandana:  The experiences and knowledge that you will gain from working in the C3B laboratories will be of benefit in both your career and life.

C3B Reporter:  Please summarize your C3B experience.

Scott:  C3B gave me a tremendous exposure to the biotech industry and the key commercial players.  I was responsible for specifying and acquiring the latest instruments for biochips research, and have established a top university research lab facility.  The research topics are exciting and interdisciplinary in nature, giving me experience in supplementing my bioengineering research with statistics and chemistry.

C3B Reporter:  What are the opportunities and challenges for the Biochips Laboratory?

Scott:  One major opportunity is the development of advanced biochips platforms for DNA microarray research.  However, the challenge is getting additional resources to address these opportunities.  Getting external funding and key people in place will continue to be objectives of the Biochips Lab.

C3B Reporter:  Describe your “dream job.”

Scott:  My dream job is to be an entrepreneur or consultant in the biotech field that gives me the autonomy to conduct research as well as to build my own business.  I have an interest in contributing to humanity/society through the implementation of innovative scientific approaches and discoveries. 

C3B Reporter:  Please answer the following rapid-fire questions for your job preferences.  Pharmaceutical or Test & Instrumentation firm?  Large or small firm?  Salary or stock options?  R&D or business development?

Scott:  Pharmaceutical.  Large firm.  Salary.  Both.

C3B Reporter:  Let’s wrap up by telling me about your musical interests.

Scott:  I am a professional flamenco guitarist who has played for fifteen years.  I also enjoy playing rock and roll as well as classical music, and own two guitars, one electric and one flamenco.  Please contact me for weddings and special occasions (TIC).
