Abstract: A micro electro mechanical system (MEMS) includes a circuit substrate comprising electronic circuitry, a support substrate having a recess, a bonding layer disposed between the circuit substrate and the support substrate, through holes passing through the circuit substrate to the recess, a first conductive layer disposed on a front side of the circuit substrate, and a second conductive layer disposed on an inner wall of the recess. The first conductive layer extends into the through holes and the second conductive layer extends into the through holes and coupled to the first conductive layer.

Abstract: A method of synthesizing carboxyl-modified molybdenum disulfide comprises the steps of a) preparing a molybdenum disulfide solution; b) adding hydrogen bromide (HBr) to the molybdenum disulfide solution, followed by blending the mixture; and c) adding oxalic acid (OA) to the molybdenum disulfide solution, followed by blending the mixture. The molybdenum disulfide synthesized by the method is applicable to a biosensing chip. The carboxyl-modified molybdenum disulfide effectively enhances sensitivity of a detection device having the biosensing chip.

Abstract: A molybdenum disulfide-containing biosensing chip includes a transparent substrate; a metal layer disposed on the transparent substrate; and a molybdenum disulfide layer disposed on the metal layer; wherein the molybdenum disulfide layer is carboxyl (—COOH)-modified. The carboxyl (—COOH)-modified molybdenum disulfide layer effectively enhances sensitivity of a detection device having the biosensing chip. The biosensing chip is applicable to detection of various biological molecules.
