TL;DR: A fingerprint lifting technique has been innovated to visualize trace TNT particulates on various surfaces by the appearance of a different color against a yellow-green background under a UV lamp, showing high selectivity and sensitivity with a detection limit as low as 5 ng/mm(2) on a manila envelope and the attribute of being seen with the naked eye.

TL;DR: The shell thickness-dependent Raman enhancement of silver-coated gold nanoparticles (Au@Ag NPs) for the identification and detection of pesticide residues at various fruit peels is reported.

TL;DR: A bright blue fluorescent graphene oxide that originates from passivation of surface reactive sites by amide formation and ring-opening amination of epoxide has been prepared and can synchronously be tuned by varying the used alkylamines.

TL;DR: A ratiometric fluorescence probe designed by hybridizing dual-emission quantum dots (QDs) and demonstrated its efficiency for on-site visual determination of copper ions, especially for visually monitoring copper residues on herb leaves.

TL;DR: A near-infrared (NIR) fluorescent probe was synthesized and demonstrated to be highly selective in reaction with hypochlorous acid (HOCl), an endogenous reactive oxygen species (ROS) produced by myeloperoxidase in neutrophils.
