Oxygen plasma treatment has been used extensively to bond polydimethyl siloxane to polydimethyl siloxane or glass in the rapid prototyping of microfluidic devices. This study aimed to improve the bonding quality of polydimethyl siloxane to passivated silicon using oxygen plasma treatment, and also to evaluate the bonding quality. Four types of passivated(More)
A voltammetric electronic tongue was developed for detecting energetic compounds in water, providing a rapid, real time method. For the presented study, a glassy carbon electrode, a platinum electrode, and a gold electrode were used to analyze target explosives, nitrotoluene, nitrobenzene, 2,4-dinitrotoluene, and 2,4,6-trinitrotoluene in water. A compact(More)
We report an inexpensive and simple approach for the fabrication of high surface area sensing elements using electrospinning. The nanofibrous membranes formed could be used as chemiresistors as well as fluorescence quenching sensors depending on the receptor used. For chemiresistor type sensors, conducting polymer (CP) nanotubes have been fabricated by(More)
