▎ 摘　　要

NOVELTY - The apparatus (1) has a graphene FET (3) comprising quantum dots (7) coupled to a graphene channel (5). The graphene FET is configured to be illuminated by a pulse of electromagnetic radiation and is configured to be exposed to a calibration sample (11) such that an output provided by the graphene FET, in response to the pulse of electromagnetic radiation, is dependent upon an analyte within the sample. The response of the graphene FET enables analyte within the sample to be classified. USE - Apparatus within sensing device (claimed) for sensing chemical analytes within sample. ADVANTAGE - A better sensing apparatus is obtained. The apparatus is calibrated so that analytes can be identified easily. The initiation of photochemical reactions and the measurements obtained at different time points enables additional information to be obtained from a sample. The apparatus can be cleaned after use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for sensing chemical analytes within a sample. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an apparatus for sensing chemical analytes within sample.
