GAAS-BASED DETECTOR HIGHLY STABLE IN AQUEOUS SOLUTIONS

摘要

The present invention provides semiconductor devices, particularly devices based on the Molecular Controlled Semiconductor Resistor (MOCSER), which are highly stable in aqueous solutions. The semiconductor devices of the invention may be used for the detection of various target molecules, e.g., proteins, peptides, carbohydrates and small molecules, in different solutions such as physiological solution, bodily fluids and bodily fluid-based solutions.

主权项

1. A semiconductor device comprising at least one conducting semiconductor layer, optionally at least one insulating or semi-insulating layer, and a protective organic molecular layer fabricated on top of an upper layer which is either one of said at least one conducting semiconductor layer or one of said at least one insulating or semi-insulating layer, protecting said upper layer from corrosion,
said protective organic molecular layer is configured such that when in contact with an aqueous solution, said semiconductor device is sensitive to pH changes in said solution both when fresh and following application of a constant electrical potential of 1 Volt through said at least one conducting semiconductor layer for a period of time of at least 10 hours.
