“…For instance, Zn(II)-coordinated peptide/F amyloid assemblies, featuring supramolecular cross-β-sheet secondary structures stabilized by hydrogen bonds, have been shown to exhibit carbonic anhydrase-like catalytic activity for ester bond hydrolysis [ 246 , 247 , 248 ]. Zhang et al demonstrated switchable hydrolase and horseradish peroxidase (HRP)-like activities of supramolecular assemblies of histidine-containing peptides through Cu(II) binding and co-assembly [ 249 ]. Liu et al reported that amyloid-like phenylalanine-Cu(II) fibrils displayed laccase-like catalytic ability and enabled the colorimetric detection of dopamine [ 250 ].…”

Over the past few decades, molecular self-assembly has witnessed tremendous progress in a variety of biosensing and biomedical applications. In particular, self-assembled nanostructures of small organic molecules and peptides with intriguing characteristics (e.g., structure tailoring, facile processability, and excellent biocompatibility) have shown outstanding potential in the development of various biosensors. In this review, we introduced the unique properties of self-assembled nanostructures with small organic molecules and peptides for biosensing applications. We first discussed the applications of such nanostructures in electrochemical biosensors as electrode supports for enzymes and cells and as signal labels with a large number of electroactive units for signal amplification. Secondly, the utilization of fluorescent nanomaterials by self-assembled dyes or peptides was introduced. Thereinto, typical examples based on target-responsive aggregation-induced emission and decomposition-induced fluorescent enhancement were discussed. Finally, the applications of self-assembled nanomaterials in the colorimetric assays were summarized. We also briefly addressed the challenges and future prospects of biosensors based on self-assembled nanostructures.

“…It has been successfully used for the degradation of chlorophenol and bisphenol and the determination of epinephrine by a smart phone. Zhang et al prepared various self-assembles with histidine-containing peptides as the precursors [ 71 ]. The peptide conformation changed from random coil to β-sheet structure and nanotube with hydrolase activity.…”

Copper ions, as the active centers of natural enzymes, play an important role in many physiological processes. Copper ion-based catalysts which mimic the activity of enzymes have been widely used in the field of industrial catalysis and sensing devices. As an important class of small biological molecules, peptides have the advantages of easy synthesis, excellent biocompatibility, low toxicity, and good water solubility. The peptide–copper complexes exhibit the characteristics of low molecular weight, high tenability, and unique catalytic and photophysical properties. Biosensors with peptide–copper complexes as the signal probes have promising application prospects in environmental monitoring and biomedical analysis and diagnosis. In this review, we discussed the design and application of fluorescent, colorimetric and electrochemical biosensors based on the peptide–copper coordination interaction.

“…Meanwhile, a large amout of nanomaterials have been proposed/developed as promising antibacterial agents, such as silver nanomaterials, 7 copper nanomaterials, 8 oxides, 9 and metal disulfide 10,11 owing to the rapid development of nanotechnology. However, these nanomaterials have achieved limited success in anti-biofilms, primarily due to their insufficient catalytic activities.…”
