Near‐Infrared Multilayer MoS2 Photoconductivity‐Enabled Ultrasensitive Homogeneous Plasmonic Colorimetric Biosensing (Adv. Mater. Interfaces 24/2021)

Abstract: Plasmonic Colorimetric Biosensing of Proteins in Biofluids In article number 2101291, Younggeun Park, Xiaogan Liang, Katsuo Kurabayashi, and co‐workers demonstrate rapid, “mix‐and‐read” detection of cancer marker proteins at sub‐femtomolar concentrations in unprocessed whole blood using a multilayered molybdenum disulfide photoconductive channel and plasmonic nanoparticles. Minimized carrier scattering within the photoconductive channel allows for detecting subtle near‐infrared light transmission shifts accomp… Show more

“…With such a mechanism, the electron flow efficiency is guaranteed. Furthermore, the charge recombination is reduced that accompanied by a higher intensity resolution [73a,82a, 84] . Despite an inorganic‐based biosensor, colorimetric biosensor can also be an organic‐derived one by involving organic substrate such as nematic LC 4‐cyano‐4′‐pentylbiphenyl (5CB), [78b] and glutaraldehyde [85] .…”

“…The selectivity of the sensing probe can be achieved by having the antigen‐antibody immunoassay [73a,77–78,80a–c,82a,83–86] or aptamer‐labelled biosensor [78d,79,80d,81] . Nevertheless, the labelled free system [78d,85] is suggested to overcome the shortcoming of labelled one as aptasensor that utilises the single‐stranded oligonucleotides chain as biorecognition site with an improved affinity towards analyte.…”
