Two undergraduates from the C3B® Lab Group attended and presented at the Biomedical Engineering Society’s Annual Meeting this year in Philadelphia, Pennsylvania.
Iris Vallavanatt (BIOL ’21), who worked with 4th year doctoral student Sara Abasi, presented her poster entitled, “Culture of HUVEC Monolayer and Effect of Tight Junction Formation on Impedance” in the undergraduate poster session. The formation of tight junctions is associated with growth to confluency of the HUVEC monolayer. Tight junction formation was visualized by staining VE-cadherin, an associated protein, to confirm the presence of tight junctions. These junctions impede ion transport between adjacent cells which can be monitored via resistance/impedance changes in ECSARA, a 24 well electroculture ware plate device designed and developed in the C3B® lab. Both results of standard alamarBlue viability assay and impedance spectroscopy showed a faster growth of EF-stimulated cells compared to the control. Therefore, a direct relationship between tight junction formation, growth to confluence, and cell resistance and capacitance exists. These parameters can be measured in real time with electrical impedance spectroscopy (EIS). Ms. Vallavanatt also volunteered at the registration desk and had the opportunity to speak with representatives from Texas A&M’s EnMed program while at BMES.
Ryan Davis (BMEN ’20), who also worked with 4th year doctoral student Sara Abasi, presented his poster entitled, “Degradation Profile and Release Kinetics of poly(HEMA-co-HPMA-co-GelMA) Hydrogel” in the undergraduate poster session. The cross-linking of HEMA-co-HPMA with methacrylated gelatin (GelMA), a modified natural polymer, gives rise to a biohybrid polymer capable of matrix metalloproteinases (collagenase) degradation. Such a polymer could be tuned to take advantage of the balance between diffusive and bio-errosive release of factors. Using FITC-dextran (40kDa) as an example, Ryan measured and modeled both the degradation kinetics and release kinetics showing the domain of influence of the studied principles of release at difference level of GelMA inclusion. Ryan visited and held discussions with several graduate schools who had representatives in attendance and renewed his commitment to attend graduate school in the Fall of 2020.
Professor Anthony Guseppi-Elie was recently selected to serve as a keynote speaker at the AfroBiotech Conference 2019 in Atlanta, GA from Oct. 27-29. The AfroBiotech Conference, hosted by the Society for Biological Engineering (SBE) of the American Institute of Chemical Engineers (AIChE), will highlight the achievements of African Americans in biotechnology, inspire a new generation of diverse biotechnology professionals and identify, communicate, and explore current advancements in various aspects of Biotechnology. Prof. Guiseppi-Elie recently shared his excitement on LinkedIn:
"Deeply honored and privileged to be selected as a #keynote speaker at the AfroBiotech Conference 2019. Hosted by the Society for Biological Engineering of the American Institute for Chemical Engineers (#LifeMember) and organized by Georgia Tech @ManuPlatt and Emory University @KarmellaHaynes, this conference features some of our nation’s top academic, industrial and publicly serving scientist, engineers and technologist in medical and biological engineering. Join us…"
Ms. Sara Abasi, Ms. Ankita Bhat, and Mr. Brandon Walther presented their graduate work at the 2019 Biomedical Engineering Graduate Student Association's Research Symposium on August 21, 2019 in the Zachry Engineering Complex at Texas A&M University. Ms. Abasi and Ms. Bhat presented long-form oral presentations. Brandon Walther, a MD-PhD student jointly directed by Prof. Guiseppi-Elie of the C3B® and Dr. John Cooke of the HMRI Cardiovascular Sciences Department has won second place among poster presenters of the 5-min Rapid Fire Talks at the 3rd Annual Research Symposium 2019 (BMEGSA) for the flash presentation entitled “Biosensor Enabled Microvasculature-on-a-Chip”. This work is groundbreaking and potentially impactful engineering work.
Ms. Sara Abasi has recently published a paper titled "Biotechnical Properties of Poly(HEMA-co-HPMA) in ACS Biomaterials. Hydrogels are Governed by Distribution among Water States" along with co-authors Dr. Daria Podstawczyk, Alycia Sherback, and Dr. Anthony Guiseppi-Elie. This paper show that it is the partitioning of water among freezable and non-freezable states that govern all the major biomedical properties of hydrogels - not the total hydration.

Ms. Ankita Bhat, a third-year doctoral student in the Center for Bioelectronics, Biosensors, and Biochips (C3B®) by Dr. Guiseppi-Elie in the Department of Biomedical Engineering at Texas A&M University, has received the prestigious National Science Foundation (NSF) fellowship to attend the 18th NSF International Summer School (2019) on Bio-X: Biocomplexity, Biodesign, Bioinnovation, Biomanufacturing and Bioenterprenuership. The 2019 summer school will be held in the Mediterranean city of Chania, on the island of Crete, from June 9-15. The fellowship will cover all the local accommodations for the student while studying in Greece. Ankita’s research involves the development of implantable biochips for physiologic status monitoring. This includes nano-enabled bio-interfaced electroconductive biosensors and biochips for the study of the complex pathophysiology of trauma-induced hemorrhage. Her research incorporates the integration of biotransducers, mixed-signal electronics, low power devices, and wireless communications into clinically relevant systems for monitoring during trauma and surgery and for monitoring in the intensive care unit (ICU). “I am excited about this global opportunity associated with the elite NSF fellowship. The Summer School will enable me to network and establish connections with participating faculty and students in the area of biosensors. I will also like to present my research and learn from others conducting research in the area of design, manufacturing, innovation, and entrepreneurship related to biosensors. This will be a wholesome experience.” said Ankita.

Ms. Ankita Bhat, a doctoral student in the Bioelectronics, Biosensors and Biochips laboratory of TEES Research Professor, Dr. Anthony Guiseppi-Elie, has received a prestigious Goa Scholars Award from the Government of Goa, India. The Goa scholars scheme was started in the year 2003-04 and since its inception, around 20 Goan students have been awarded the prestigious 'Goa Scholar' scholarships each year. The Goa Scholars Award is accompanied by a one-time US $20,000 award for studies at Texas A&M University. Ms. Bhat’s doctoral work focuses on the development of minimally-invasive, multi-analyte biosensor arrays and data fusion for the management of trauma associated hemorrhage. Her multi-disciplinary engineering and medicine research allows her to apply engineering principles and know how to address pressing problems in patient care. “Our goal is to better understand hemodynamics of the bleeding patient so that we may develop better and even personalized approaches to resuscitation and reanimation,” said Prof. Guiseppi-Elie. “The prestige associated with this award is great, it is a great honor and responsibility” said Ankita.
Professor Guiseppi-Elie served as the Organizing Chair for the Spring 2018 EnMed Lasker Lecture and Biomedical Imaging Symposium (https://enmed.tamu.edu/lasker-lecture-biomedical-imaging-symposium/) on April 25-26 in the Houston Medical Center. EnMed, a partnership between the Texas A&M University College of Engineering, College of Medicine and Houston Methodist Hospital, is an innovative integrated educational and research medical program with a focus on innovation and entrepreneurship.
John Aggas, a doctoral student in the Guiseppi-Elie Lab of the Center for Bioelectronics, Biosensors and Biochips in the Department of Biomedical Engineering at Texas A&M University, received a National Science Foundation (NSF) fellowship to attend the 16th NSF International Summer School (2017) on Bio-X: Biocomplexity, Biodesign and Bioinnovation.
Aggas started at Texas A&M in the spring of 2016 and is in his third semester. Currently he is pursuing research in the field of biologically responsive and biocompatible polymeric circuit elements for implantable biosensing.
His research consists of utilizing a conductive nanofiber synthesized from polyaniline that is dispersed within a hydrogel to develop both resistive and capacitive circuit elements. These elements, when integrated with biological recognition molecules such as enzymes, can demonstrate a biological response to physiological metabolites, such as glucose or lactate. The result is the ability to create organic circuits that signal levels of lactate and glucose.
