A non-enzymatic electrochemical technique for creatinine sensing is presented, exploiting iron binding property of creatinine. Disposable carbon printed electrodes layered with FeCl3 coated cotton fiber membranes are used to sense creatinine from 10 to 245 mg/dl, on clinical urine samples. The energy-dispersive X-ray spectroscopy analysis confirms the presence of Fe(III) dry chemistry on cotton membrane...
This paper presents a novel handheld electrochemical workstation for serum albumin measurement. The system consists of a multi-path potentiostat module which performs electrochemical measurements on disposable test strip. The strip provides a port for applying blood sample. The test strip consists of 3 electrochemical cells for redundancy and parallel testing. The 3 sets of 3 electrodes (Working,...
In this paper we present a smart handheld system for point of care biosensors. The system consists of a novel multi-path potentiostat module which performs electrochemical measurements on disposable test strip. The strip provides a port for applying bio-sample such as blood or urine. The analyte port on the disposable strip is designed with 3 sets of 3 electrodes (Working, Reference and Counter electrodes)...
We report on a cost effective, portable urban air pollution monitoring device, Envirobat, based on commercially available gas sensors. In order to carry out air pollution monitoring over an extensively large area, the device integrates inexpensive solid state sensors, along with GSM Module which transmits measured data at multiple ground sites to a centralized server through GPRS. This device facilitates...
