Preparation and characterization of a homogeneous immunoassay for point-of-care testing (POCT) of procalcitonin (PCT)

Abstract

Sensitive Measuring Interaction-triggered Luminescence Experiment (SMILE), a homogeneous immunoassay method, was established for point-of-care testing (POCT) of procalcitonin (PCT).

Sodium alginate hydrogelation mediated paper-based POCT sensor for visual distance reading and smartphone-assisted colorimetric dual-signal determination of l-lactate

“…20 At present, several POCT detection sensors have been developed, such as paper-based sensors, 21–23 colorimetric sensors, 24,25 and immunofluorescence sensors. 26–29 Glass, silicon, polydimethylsiloxane (PDMS), paper, and wires are often utilized as carriers for POCT, and they have become important components of POCT. 30 Among these materials, paper-based sensors are widely used in biomedical detection, microbial detection, environmental control, and food detection owing to their advantages of feasibility, 31 portability, cost-effectiveness, 32,33 recyclability, and environmental degradability.…”
