Colorimetric sensors: taking merits of nanofibrous membrane for volatile toxicants detection with ultra-high sensitivity

Discovery of Peptidic Ligands against the SARS-CoV-2 Spike Protein and Their Use in the Development of a Highly Sensitive Personal Use Colorimetric COVID-19 Biosensor

“…In addition, the platform in which these affinity elements are deployed can boost the assay’s performance and miniaturize the assay, affording more user-friendly biosensors. Microporous nanofibrous membranes have found unique advantages in the development of highly sensitive colorimetric sensors due to the structural characteristic of extremely high specific surface areas allowing increased loading of affinity elements, leading to dramatically intensified colorimetric signals high enough for human eye detection. − The integration of both SARS-CoV-2 S-protein selective binding peptides and nanofibrous membranes could lead to the development of biosensors against COVID-19 with desired selectivity, sensitivity, and easy-to-use functions.…”
