Cellular compartmentalization is a fundamental property of living cells that allows the positioning and separation of biomolecules and biochemical processes within distinct compartments.1-3 This compartmentalization ensures cellular functionality and behavior, and provides the basis for the remarkable efficiency of cells as adaptive biochemical reactors.4 Inspired by this natural organization, biomimetic compartmentalized systems with life-like properties have been developed, including...

AbstractStimuli-responsive hydrogels with programmable shape changes are promising materials for soft robots, four-dimensional printing, biomedical devices and artificial intelligence systems. However, these applications require the fabrication of hydrogels with complex, heterogeneous and reconfigurable structures and customizable functions. Here we report the fabrication of hydrogel assemblies with these features by reversibly gluing hydrogel units using a photocontrolled metallopolymer adhesive.

Introduction A droplet of water easily glides across the surface of a thick oil layer due to negligible interfacial friction and the absence of defects. This frictionless scenario can be replicated on solid surfaces by trapping an infused interfacial layer of air (as in superhydrophobic surfaces),1 or of oil (as in lubricant-infused surfaces)2 using micro- and nano-textures.

Abstract Slippery covalently-attached liquid surfaces (SCALS) with low contact angle hysteresis (CAH, <5◦) and nanoscale thickness display impressive anti-adhesive properties, similar to lubricant-infused surfaces. Their efficacy is generally attributed to theliquid-like mobility of the constituent tethered chains. However, the precise physico-chemical properties that facilitate this mobility areunknown, hindering rational design.
