▎ 摘　　要

NOVELTY - Portable device comprises a sensor module disposed in a housing, where the sensor module collects data for detecting and identifying one or more antibody compounds, a biosensor array connected to a device, a communication apparatus disposed to the sensor module, where the communication apparatus electrically transmits the data collected by the sensor module, and a battery disposed to the communication apparatus and the sensor module. USE - The portable device is useful for detecting and identifying virus antibody compounds in a swab, saliva or blood specimen sample of a subject or detecting and identifying antibody compounds in a sample specimen of a subject (claimed). The subject is human. ADVANTAGE - The portable device rapidly and easily detects and identifies virus antibody compound. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a biosensor comprising a counter electrode, one or more working electrodes comprising carbon nanostructure materials or gold nanoparticles graphene composites, where the working electrodes comprise immobilized biological molecules, a reference electrode, and a support on which the electrodes are disposed; and (2) a method for detecting and identifying antibody compounds in a sample specimen of a subject involves transmitting the sample specimen of a subject collected on a biosensor array to a housing, where the biosensor array is connected to the housing, where the housing comprises a sensor module, a communication apparatus and a battery, collecting data about the presence and identity of the compounds with the sensor module, communicating the collected data through the communication apparatus to a processing apparatus, and processing the communicated data to detect and identify the antibody compounds in the sample specimen.
