TL;DR: The as-proposed label-free and enzyme-free homogeneous electrochemical strategy may become an alternative method for simple, sensitive, and selective miRNA detection, and it has great potential to be applied in miRNA-related clinical diagnostics and biochemical research.

TL;DR: In this paper, a 2D tandem nanozyme with tandem enzyme-like characteristics is presented for the colorimetric detection of glucose, where the oxidation of glucose and the detection of H2O2 are simultaneously conducted under the catalysis of the single nanozyme (MnO2 NFs).

TL;DR: It is demonstrated that the as-prepared textile not only can be applied as effective membrane materials for the separation of oil and water mixtures with high separation efficiency (>97%), but also can be used as a bag for the selective oil adsorption from water.

TL;DR: A truly immobilization-free diffusivity-mediated PEC bionsensing strategy for microRNA assay, using methylene blue in solution as the photoactive probe, and nonmodified indium tin oxide (ITO) glass as the working electrode, which is successfully applied in detecting microRNA spiked in serum samples.

TL;DR: The present assay enables the detection of telomerase activity at the single-cell level, which is superior or comparable to that of the reported literature, and was carried out in a homogeneous solution without complex modification or immobilization procedures, which has the merits of simplicity, rapid response, and improved recognition efficiency compared with heterogeneous biosensors.
