Bandage-like wearable flexible microfluidic recombinase polymerase amplification sensor for the rapid visual detection of nucleic acids

Abstract

With the development of flexible advanced materials and microfluidic technology, wearable biosensors provide a new strategy for the continuous monitoring of health. In this study, a novel bandage-like wearable flexible microfluidic recombinase polymerase amplification (RPA) sensor was constructed for the rapid and visual detection of nucleic acids. This wearable sensor is triggered by human body heat (30°C-37 °C) and allows for visual nucleic acid (a conserved nucleic acid fragments of zika virus) detection within 10 min. The sensor displays good sensitivity and selectivity, with a detection limit of 10 copies/μL. The wearable sensor has exhibited well-defined accuracy when applied to testing clinical serum samples. In addition, the wearable RPA sensor was proved to be feasible by human trials under different daily activities. This wearable sensor of nucleic acids will probably be of great significance in the field of online pathogen detection for wounds, for tumour biomarker diagnosis, and for the detection of epidermal cell molecular lesions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
