Advanced Functional Materials, EarlyView.The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.

Reversible Tuning of Multiple Molecular Kinking for Stem Cell Regulation In Vivo
Advanced Functional Materials, EarlyView.In this work, we introduce the novel concept of background component‐free “multiple kinks” material platform composed solely of liganded multiple kink‐bearing molecules as a strategy for dynamic biomaterial design. Tri‐kink molecules enable effective near‐infrared light‐triggered ligand masking and visible light‐triggered ligand exposure, thereby ...
