Engineers at MIT have devised a method to bind two stretchy materials: gelatin-like polymer materials called hydrogels, and elastomers, which are impervious to water and can thus seal in the hydrogel’s water.Photo credit: Melanie Gonick/MITIf you leave a cube of Jell-O on the kitchen counte...
If you leave a cube of Jell-O on the kitchen counter, eventually its water will evaporate, leaving behind a shrunken, hardened mass—hardly an appetizing confection. The same is true for hydrogels. Made mostly of water, these gelatin-like polymer materia
hydrogels were brittlely exposed to cross sections with liquid nitrogen and sputtered with gold, followed by SEM (HITACHI SU8220) test. Tensile tests The mechanical properties of hydrogel fibers were tested by using a universal tester (AGS-X) with an environmental chamber and a liquid nitrogen ...
those grown on our soft hydrogels were governed by cell–cell interaction due to the relatively low cell–ECM interaction, thereby leading to the formation of cell colonies and collective cell migration. At this stage, we could not conclude which scenario is more favorable for endothelial regenerati...
This anti-freezing tough gel opens up new possibilities for the application of hydrogels as actuators, soft robotics, and flexible electronics under subzero temperatures. Results and discussion Fabrication and structure Tendons are strong cords of fibrous material that transmit force from muscles to ...
