Abstract
Presented herein are systems, methods, and architectures related to functionalization of the metallic gates of field-effect transistors (FETs) and the use of the functionalized FETs as biochemical sensors in liquid samples. The functionalization can either be a molecularly imprinted polymer or a probe material. The functionalized FETs can be used in devices for analyte detection/quantification. In particular, the functionalized FETs are used in devices for the detection and/or quantification of cytokines (e.g. interleukin) and/or cholesterol (LDL or HDL).
