Abstract: The present invention relates to nanoprocessing and heterostructuring of silk. It has been shown that few-cycle femtosecond pulses are ideal for controlled nanoprocessing and heterostructuring of silk in air. Two qualitatively different responses, ablation and bulging, were observed for high and low laser fluence, respectively. Using this approach, new classes of silk-based functional topological microstructures and heterostructures which can be optically propelled in air as well as on fluids remotely with good control have been fabricated.
