NOVELTY - System 100 comprises a biosensor including at least one field-effect transistor along a length of an apparatus, at least one field-effect transistor having one or more capture proteins conjugated to it, and one or more capture proteins being configured to bind a virus in the effluent, a fluidic channel 104 arranged above field-effect transistor and along the length of apparatus such that fluid of effluent flows over field-effect transistor by the fluidic channel, and a processing circuitry configured to apply a gate voltage to each of the at least one field-effect transistor, measure a conductance across each of the at least one field-effect transistor, a change in the conductance based on an amount of the virus bound to the one or more capture proteins, compare the measured conductance across each of the at least one field-effect transistor to a threshold conductance, and transmit information indicating a presence of virus in the effluent to a computing device. USE - System for monitoring viral loads in effluent. ADVANTAGE - The system has ability to make highly sensitive and instantaneous measurement using small amount of analyte or antigen. DETAILED DESCRIPTION - System comprises a biosensor including at least one field-effect transistor along a length of an apparatus, at least one field-effect transistor having one or more capture proteins conjugated to it, and one or more capture proteins being configured to bind a virus in the effluent, a fluidic channel arranged above field-effect transistor and along the length of apparatus such that fluid of effluent flows over field-effect transistor by the fluidic channel, and a processing circuitry configured to apply a gate voltage to each of the at least one field-effect transistor, measure a conductance across each of the at least one field-effect transistor, a change in the conductance based on an amount of the virus bound to the one or more capture proteins, compare the measured conductance across each of the at least one field-effect transistor to a threshold conductance, and transmit information indicating a presence of virus in the effluent to a computing device when the comparison indicates the measured conductance across each of the at least one field-effect transistor satisfies the threshold conductance.
