Protein micro/nanopatterning has long provided sophisticated strategies for a wide range of applications including biointerfaces, tissue engineering, optics/photonics, and bioelectronics. We present here the use regenerated silk fibroin to explore wrinkle formation by exploiting structure-function relation silk. This yields biopolymer-based reversible, multiresponsive, dynamic wrinkling system based on protein's responsiveness external stimuli that allows on-demand tuning surface...
Abstract Natural systems display sophisticated control of light-matter interactions at multiple length scales for light harvesting, manipulation, and management, through elaborate photonic architectures responsive material formats. Here, we combine programmable function with elastomeric composites to generate optomechanical actuators that controllable tunable actuation as well complex deformation in response simple illumination. The ability topographically bandgaps allows the substrate...
Abstract Structurally colored materials, which rely on the interaction between visible light and nanostructures, produce brilliant color displays through fine control of interference, diffraction, scattering, or absorption. Rationally combining different color‐selective functions into a single form offers powerful strategy to create programmable optical are otherwise difficult, if not impossible obtain. By leveraging structural protein templates, specifically silk fibroin, nanostructured...
Abstract In recent years, increased control over naturally derived structural protein formulations and their self‐assembly has enabled the application of high‐resolution manufacturing techniques to silk‐based materials, leading bioactive interfaces with unprecedented miniaturized formats functionalities. Here, a hybrid biopolymer–semiconductor device, obtained by integrating nanoscale silk layers in well‐established class inorganic field‐effect transistors (silk‐FETs), is presented. The...
Abstract The quest for flexible curvilinear displays is driving renewed interest in natural soft photonic systems that rely on the adaptable response of nanostructured living tissues to external stimuli camouflage and energy management. Understanding controlling dynamics these challenging due difficulties sourcing constraints ability stimulate them. Here, we present an ex-vivo approach systematically investigate biophotonic crystals dynamically control their by using Bos taurus tapetum as a...
