Peptide‐Based Organic‐Inorganic Hybrid Self‐Assemblies for Ultrasensitive and Visual Detection of Heparin (Adv. Funct. Mater. 22/2024)

Self‐Assembly for Ultrasensitive Detection In article number 2314832, Hai Zhang, Xiaofei Chen, Quan Li, and co‐workers report a peptide‐derived supramolecular self‐assembly system for ultrasensitive and visual detection of heparin in vivo. Two peptides are designed and modified by gold nanocluster and tetraphenylethene to co‐assemble into nanoparticles for co‐recognition of heparin. The new approach reaches an extreme low limit of detection and dramatic fluorescence color change to be simply distinguished on paper by naked eye.
