RNA aptamer-packaged virus-like particles for label-free, rapid, and on-site fluorescence detection of malachite green in aquatic products.

Abstract

Malachite green (MG) is a banned antimicrobial dye widely used in aquaculture, whose persistence and toxicity pose serious risks to human health and the environment. Rapid, on-site detection of MG residues in aquatic products is essential for food safety surveillance. Here, we report a label-free fluorescence biosensor based on RNA aptamer-packaged virus-like particles (RNApt
