A novel rapid immunosensor using a polymerized enzyme conjugate tracer enables highly sensitive, cost-effective, and rapid (25 min) point-of-care detection of hs-cTnI.
To detect high-sensitivity cardiac troponin I (hs-cTnI; 0.99). The detection limit of the rapid immunosensor was 0.003 ± 0.001 ng/mL cTnI, corresponding to a 10-fold improvement compared to results using the plain enzyme tracer. This demonstrated the measurement of hs-cTnI in a much more cost-effective manner compared to the automated versions currently available.
