Gallic acid (GA) is a naturally occurring plant phenol known for its anti-inflammatory and antioxidant properties. In this work, we probed the molecular self-assembly of GA for the development of GA based nanocomposites for potential device fabrications and enhanced antioxidant applications. We found that the formation of GA nanostructures was pH dependent. Further, we examined the interactions of selenite with GA and subsequently examined the biomimetic formation of selenium (Se) nanoparticles. We found that in the presence of selenite, the yield of nanofibers was significantly higher, and selenium nanoparticle coated nanofibers were formed. The ability of the nanocomposites to scavenge free radicals was also explored. Thus, we have developed a new family of Se nanoparticle coated GA nanofibers, which could not only be applicable as potent antioxidants at the nanoscale but may also have potential applications in optoelectronics and sensors.
