The structural arrangement of amino acid residues in a native enzyme provides blueprint for the design artificial enzymes. One challenge mimicking catalytic center is how to arrange essential an appropriate position. In this study, we designed hydrolase via self-assembly short peptides catalyze ester hydrolysis. When assembled sites were embedded matrix peptide nanofibers, they exhibited much higher efficiency than nanofibers without sites, suggesting that well-ordered nanostructure...
Flexible pressure sensors have attracted much attention due to their significant potentials in E-skin, artificial intelligence, and medical health monitoring. However, it still remains challenging achieve high sensitivity wide sensing range simultaneously, which greatly limit practical applications for flexible sensors.

The fluorescence of tetraphenylethylene (TPE), an archetypal luminogen, is induced by restriction intramolecular rotation (RIR). TPE was grafted with palmitic acid (PA) onto a hydrophilic peptide to yield cell membrane tracker named TR4. TR4 incorporated into liposomes, where it showed significant RIR characteristics. When cells were incubated TR4, cytoplasmic membranes specifically labeled. shows excellent photostability and low cytotoxicity.
