Using a short peptide precursor modified by the biaryltetrazole with intramolecular photo-click reactivity, we realized the photo-regulation of the pericellular nanofibers formed by the enzyme-instructed self-assembly on the cell membrane. Upon light irradiation, the fluorescence of nanofibers could be turned on to monitor both enzyme-instructed self-assembly and photo-induced disassembly processes. Moreover, the cell fate could be controlled through the photo-regulation.

Recently, artificially structured metamaterials (MMs) are proposed to manipulate the wave propagation behaviors in single physical domain. However, the multiphysics manipulation is rarely reported and remains a challenging issue to be investigated. Here, the design of MMs with simultaneous controls of acoustic and electromagnetic (EM) waves is presented. A double-membrane structure is proposed to meet the need of acoustic-wave insulation, and patterned anisotropic meta-atoms on the membrane are employed to generate polarization-dependent functions of EM waves. The designed structure is validated numerically and experimentally, suggesting a new route for joint modulations of acoustic and EM waves in the engineering. www.advmattechnol.de further confirmed by experimental results, which suggests a promising route toward the design of such bifunctional devices.
