Scalable Graphene Aptasensors for Drug Quantification
Ramya Vishnubhotla, Jinglei Ping, Zhaoli Gao +4
Simpler and more rapid approaches for therapeutic drug-level monitoring are highly desirable to enable use at the point-of-care. We have developed an all-electronic approach for de…
pH sensing properties of flexible, bias-free graphene microelectrodes in complex fluids: from phosphate buffer solution to human serum
Jinglei Ping, Jacquelyn E. Blum, Ramya Vishnubhotla +5
Advances in techniques for monitoring pH in complex fluids could have significant impact on analytical and biomedical applications ranging from water quality assessment to in vivo…
An aptamer-biosensor for azole class antifungal drugs
Gregory R Wiedman, Yunan Zhao, Arkady Mustaev +4
This report describes the development of an aptamer for sensing azole antifungal drugs for therapeutic drug monitoring. Modified Synthetic Evolution of Ligands through Exponential…
Structural-Functional Analysis of Engineered Protein-Nanoparticle Assemblies Using Graphene Microelectrodes
Jinglei Ping, Katherine W. Pulsipher, Ramya Vishnubhotla +6
The characterization of protein-nanoparticle assemblies in solution remains a challenge. We demonstrate a technique based on a graphene microelectrode for structural-functional ana…
Scalable production of high sensitivity, label-free DNA biosensors based on back-gated graphene field-effect transistors
Jinglei Ping, Ramya Vishnubhotla, Amey Vrudhula +1
Scalable production of all-electronic DNA biosensors with high sensitivity and selectivity is a critical enabling step for research and applications associated with detection of DN…
Quantifying the intrinsic surface charge density and charge-transfer resistance of the graphene-solution interface through bias-free low-level charge measurement
Jinglei Ping, A. T. Charlie Johnson
Liquid-based bio-applications of graphene require a quantitative understanding of the graphene-liquid interface, with the surface charge density of adsorbed ions, the interfacial c…
