a. Photo (top) and cryo-HRSEM (bottom) images of poly(Lys-25) hydrogel to show macroscopic and microscopic gel behavior. At low temperature (4°C), the gel is in expanded state (left). At high temperature (40°C), the gel is in collapsed state (right). b. Schematic of LysB10 showing crosslinking primary amine sites and hydrophobic plastic-like endblock and hydrophilic elastic-like central block.
