TL;DR: A novel, simple and label-free fluorescent aptasensor, based on quaternized tetraphenylethene salt, graphene oxide and AFB1 aptamer, has been constructed to detect AFB1 and is highly selective against other aflatoxins in foods.

TL;DR: A novel fluorescent aptasensor using metal-organic frameworks (UiO-66-NH2) and TAMRA label aptamer as sensing platform for AFB1 detection and provided a reasonable method for other mycotoxin detection by changing the sequence of aptamer.

TL;DR: A colorimetric and ratiometric fluorescent probe (AC-6ED) with anthracene carboximide as fluorophore and ethylenediamine group as recognition moiety has been developed for phosgene detection in solutions and in the gas phase based on the intramolecular charge transfer (ICT) mechanism as discussed by the authors.

TL;DR: A novel ratiometric fluorescence probe (AC-SA), in which anthracene carboximide and secondary amines at the 6th position of the fluorophore severed as recognition moiety is rationally designed to detect NO, which can be applied to image endogenous NO in Raw 264.7 macrophage cells as well as zebrafish in aRatiometric manner.

TL;DR: In this paper, the authors summarized recent developments in colormetric, electrochemical, SERS, and fluorescent aptasensors for the quantification of AFB1 and outlined the perspectives and current challenges of aptamers for AFB1.
