摘要： The present invention provides for photonic nanoimprinted silk fibroin-based materials and methods for making same, comprising embossing silk fibroin-based films with photonic nanometer scale patterns. In addition, the invention provides for processes by which the silk fibroin-based films can be nanoimprinted at room temperature, by locally decreasing the glass transition temperature of the silk film. Such nanoimprinting process increases high throughput and improves potential for incorporation of silk-based photonics into biomedical and other optical devices.

摘要： The invention provides for compositions and process for fabricating an optical reflector constructed from biocompatible and bioresorbable silk fibroin proteins. For example, the silk retroreflectors may be built based on millimeter size microprism arrays to rotate the image plane of imaged cortical layers, thus enhancing the amount of photons that are detectable in the reflected direction when inserted in a sample to be analyzed, and ultimately increasing in contrast ratio in multiphoton microscopy. Such device can be used as a label-free, biocompatible, bioresorbable, implantable device for various applications ranging from medical imaging/diagnostics, drug/therapeutic delivery, to food chain safety and environmental monitoring.
