TL;DR: This novel, simple, visual and label-free method for telomerase detection by using enzymatic etching of gold nanorods (GNRs) was considerably suitable for point-of-care diagnostics in resource-constrained regions because of the easy readout of results without the use of sophisticated apparatus.

TL;DR: In this paper, a boron-doped diamond (BDD) electrode was modified with a nanocomposite prepared from carbon spheres (CSs; with an average diameter of 500nm) that were synthesized from resorcinol and formaldehyde, and then were coated with gold nanoparticles (AuNPs) by chemically growing them of the CSs.

TL;DR: A simple and sensitive electrochemiluminescence (ECL) aptasensor constructed to detect OTA based on ECL-RET and a nicking endonuclease-powered DNA walking machine showed an excellent selectivity for OTA over other mycotoxins.

TL;DR: A simple colorimetric strategy for label-free quantification of human telomerase activity in urine by using hemin-graphene nanomaterial (H-GNs), which has the linear range from 100 to 2300 HeLa cells/ mL and the detection limit was 60 cells/mL and has been successfully applied to detect telomerases activity in real urine samples.

TL;DR: A visual detection method for miRNA 155 based on DNAzyme amplification strategy in living cells based on linear range from 0.1 to 10 nM and a low detection limit of 44 pM on in vitro detection is established.
