Digital‐Resolution Biosensing
In article number 2210561, Ting Xu, Yuzhang Liang, Cheng Yang, and co‐workers report a plasmon‐enhanced ultrasensitive and selective digital‐readout imaging immunoassay for microRNA quantification. The microRNA molecules are translated into digitally distinguishable nanoparticle attachment onto a large‐area Au‐SiO2 bilayer film, forming plasmonic nanocavity enhanced digital...
Digital imaging immunoassays for precisely detecting microRNAs have attracted much attention in early cancer diagnosis. Currently, there is an urgent demand for improving the sensitivity and selectivity in digital immunoassays, which is limited by low imaging signal‐to‐noise ratio and pollutant interference. Herein, a plasmon‐enhanced ultrasensitive and selective digital‐readout imaging immunoassay...
