Medical Diagnostics: Quick Blood Testing

IME researchers have developed an integrated chip for determining protein biomarkers in blood. The chip can detect three cardiac biomarkers from a fingerprick of blood in 45 mins and it is one order of magnitude higher in sensitivity than conventional enzyme linked immunosorbent assay (ELISA) method. The chip may be harnessed for point-of-care devices for rapid and sensitive diagnosis in heart patients.
