Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Multiplex visual nucleic acid detection via isothermal cascaded transcription of fluorescent RNA aptamers

VIEW, EarlyView.
(1) Existing multiplex nucleic acid detection struggles to combine high sensitivity, visual readout, and instrument‐free use, which is vital for rapid infection and antibiotic resistance diagnosis. (2) We developed MAGIC, integrating isothermal cascaded amplification and fluorescent RNA aptamer transcription, achieving 10 aM sensitivity, 100% accuracy ...
