Advanced Functional Materials, EarlyView.Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Atmospheric Doping of Stretchable Polymer Semiconductors for Skin Electronics
Advanced Functional Materials, EarlyView.An atmospheric doping system using oxygen molecules in air as dopants is introduced for stretchable polymer semiconductors. The chemisorbed oxygen molecules act as acceptor, lead to increase not only the hole concentration of the semiconductor film over two orders of magnitude (3.37 × 1017 cm−3) but also electrical properties of the field‐effect ...
