Title of dissertation: INTEGRATED CMOS CAPACITANCE SENSOR AND MICROACTUATOR CONTROL CIRCUITS FOR ON-CHIP CELL MONITORING Somashekar Bangalore Prakash Doctor of Philosophy, 2008 Dissertation directed by: Professor Pamela Abshire Department of Electrical and Computer Engineering “Cell Clinics,” CMOS/MEMS hybrid microsystems for on-chip investigation of biological cells, are currently being engine...

We present a compact and lightweight liquid chromatography system. This system consists of a battery-powered electroosmotic flow pump, a 20-nL injector, a microchip contains a reversed phase packed column and an electrochemical detector, and a handheld potentiostat powered by a universal serial bus (USB) connected to a laptop computer. The system has overall dimensions of approximately 26 cm wi...

The BRODERICK PROBE® encompasses several formulations of carbon-based biosensors, patented by City University of New York (CUNY) and assigned to CUNY and in part to NYU Medical Center of NYU; all patents describing in detail, the series of nanobiosensors are held by Eazysense Nanotechnologies Incorporated in New York State in concert with CUNY Technology Commercialization Office (TCO). Nanobios...

A flow-injection pulse amperometric method for determining tacrine, based on ion transfer across a plasticized poly(vinyl chloride) (PVC) membrane, was developed. A four-electrode potentiostat with ohmic drop compensation was used, while a flow-through cell incorporated the four electrodes and the membrane, which contained tetrabutylammonium tetraphenylborate. The influence of the applied poten...

The potentiostat is critical in the development of electrochemical systems; however, its cumbersome detection and high cost considerably limit large-scale application. To provide an affordable alternative to developing countries resource-constrained areas, this study designs system based on smartphones, which uses Bluetooth Low Energy convert open-source data PSoC-5LP.

Sequential injection system (SI system) was used for the pretreatment of a carbon electrode in an anodic stripping voltammetry (ASV) for the determination of arsenic (III). In this research, a screen-printed carbon electrode (SPCE) was used; SPCE was prepared in our laboratory by us. In ASV, SPCE was chosen as a working electrode because SPCE is less expensive, easy to use for a flow cell and s...

In this study, the bio-electrochemical response of the Ti–Zr–Si thin film metallic glasses (TFMGs) in simulated body fluid with different contents of titanium is measured via potentiostat. According to the results of bio-corrosion potential and current, as well as the polarization resistance, it is concluded that the Ti66Zr25Si9 TFMGs possess the highest bio-electrochemical resistance. With inc...
