An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

open access: yesAdvanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
