▎ 摘　　要

NOVELTY - Biosensor comprises a multiplexed array of electrolyte-gated FET, separating walls on an upper surface of the multiplex array, where the walls fluidically separate each of the FETs from one another, and a perimeter wall on the upper surface of the multiplex array surrounding the separating walls and traversing the surface of all FETS in the multiplexed array, where the perimeter all form a fluidically tight well traversing multiple ones of the FETs, the fluidically sealed well subdivided into a many of chambers, each chamber corresponding to one of the FETs in the microarray, each FET comprises monolayer of a two dimensional (2D) material as a conducting channel, and each conducting channel functionalized according to a predetermined agent. USE - The biosensor is useful for: multitargeted, and modular virus sensing platform; and detecting perhaps any other viral bodies (e.g. Ebola or others) or for detection of hormones, DNAs, and protein. ADVANTAGE - The biosensor: improves graphene substrate adhesion; a low limits of detection and fast response time; provides a rapid response e.g. within minutes, early stage diagnosis tool that differentiates between multiple analytes of choice embodied into a single device, which allows for point of care monitoring. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for forming a biosensor comprises forming many electrolyte-gated graphene based FET on a substrate, where each GFET comprises monolayer of graphene as a conducting channel, and each conducting channel is functionalized according to a predetermined agent, and providing a fluidically sealed well on a surface of the many of GFETs and a many of fluidically sealed walls between the GFETS within a perimeter of fluidically sealed well.
