A precise and simple in-situ voltammetric measurement of promethazine, based on the nano sized molecularly imprinted polymer (nano-MIP) was introduced. The nano-MIP was synthesized utilizing vinyl benzene and Divinylbenzene as the functional monomer and cross-linker respectively, and via the micro-emulsion polymerization method in silicon oil. The MIP particles were then embedded in a carbon pa...

This paper reports a nano-opto-mechanical pressure sensor based on nano-scaled ring resonator. The pressure is measured through the output spectrum shift which is induced via mechanical deformation of the ring resonator. The sensitivity as high as 1.47 pm/kPa has been experimentally achieved which agrees with numerical prediction. Due to the strong variation of sensitivity with different ring r...

Sensitive and selective sensor system is required to detect causes of disease. It is able to detect the cause of the disease more effectively by using multi-modal properties of nano-bio sensors. Some peak detection algorithms which are suitable for implementing with micro-controller are compared to apply to multi-modal nano-bio sensors in this paper. It is shown that autothreshold peak detectio...
