Label-free and enzyme-free fluorescent biosensor for ultrasensitive detection of tobramycin via cascade signal amplification.

A novel enzyme-free and label-free fluorescent biosensor based on a cascade signal amplification strategy, integrating an entropy-driven DNA circuit (EDC) with catalytic hairpin assembly (CHA) that offers a promising platform for food safety supervision and clinical diagnostics.

HCR-assisted CRISPR/Cas12a platform enables logic-gate and multimodal detection of kanamycin and bisphenol A.

A novel triple-modal biosensor integrating hybridization chain reaction (HCR) with CRISPR/Cas12a was developed for sensitive and selective detection of kanamycin (KANA) and bisphenol A (BPA). The system employs a phosphorothioate-modified G-rich hairpin (SHG4-2) as a dual-functional reporter probe, which resists Cas12a...
