摘要： A device for detection of tetrahydrocannabinol or THC in a sample includes a sensor including a substrate and a sensor medium on the substrate. The sensor medium includes at least one nanostructure, wherein at least one property of the sensor medium is dependent upon the presence of THC on a surface of the sensor medium. The device further includes electronic circuitry including at least one measurement system in operative connection with the sensor to measure a variable relatable to the at least one property of the sensor medium dependent upon the presence of THC.

摘要： A method of detecting an analyte in a fluid sample includes exposing a sensor including a substrate and a sensor medium on the substrate to the fluid sample for a period of time. The sensor medium includes a plurality of nanostructures and one or more of at least one agent selected from the group consisting of an antibody, an antigen receptor or an antigen immobilized upon at least a portion of the plurality of nanostructures. The at least one agent is an antibody or an antigen receptor if the analyte is an antigen and is an antigen if the analyte is an antibody. An electrolyte liquid having a known ionic strength which is less than the fluid sample is added over the sensor medium subsequent to exposing the sensor to the fluid and a variable providing a measure of change in at least one property of the sensor medium which is dependent upon the presence of the analyte is measured in presence of the electrolyte liquid.
