Although the encrypted anti‐counterfeiting technology based on infiltration‐controlled photonic crystals has attracted widespread attention, the information has only hidden and display states. The more diverse and complex encryption effect requires a continuous and programmable color transformation. Inspired by the dynamic camouflage in chameleons and cephalopods, a programmable thermochromic patterned...
Biology provides a range of materials, mechanisms, and insights to meet the diverse requirements of nanomedicine. Here, a biologically based nanoparticle coating system that offers three characteristic features is reported. First, the coating can be self‐assembled through a noncovalent biospecific interaction mechanism between a lectin protein (Concanavalin A) and the polysaccharide glycogen. This...
