Summary: Pinpoint's nanosensor-based platform detects SARS-CoV-2 antigen by (1) measuring baseline current through our functionalized nanosensor chip in ordinary PBS buffer; (2) measuring the change in current at specific voltage ranges after insertion of the specimen as a result of binding between probe aptamer and target antigen; (3) computing delta between these two measurements. These measurements and computations are performed internally in quadruplicate, with four separately measured nanosensor channels. Consolidated results are reported to the user as {Detected; Not Detected; Inconclusive; or Error}.
