Metallic nanomaterial decorated silk films as flexible, biocompatible SERS substrates
Research Mentor(s)
Ying Bao and Amanda Murphy
Description
Metal nanomaterials, including gold and silver, have obtained tremendous attention due to their fascinating optical properties. Such properties make them great candidates for improving the development of optical sensors. For example, surface-enhanced Raman scattering-based sensors are one of the most well-known and popular sensors in recent research due to their ability to detect and enhance signals of minute target analytes. And silk films are used as a platform due to their properties as mechanically stable, biocompatible conducting polymers. This work presents effective methods to fabricate biocompatible metallic nanomaterial decorated silk films using gold and silver. The films are first modified to hold a positive surface charge, which is followed by a seed-mediated electroless deposition of select metals. Scanning electron microscopy was used to characterize the morphology of the resulted thin films. The results indicate that the distribution and morphology of metallic nanomaterial can be controlled, providing promising potential for developing novel biosensors.
