Tiny micro- and nanoscale structures within a material’s surface are invisible to the naked eye, but play a big role in determining a material’s physical, chemical, and biomedical properties. Over the past few years, Chunlei Guo and his University of Rochester team found ways to manipulate those structures by irradiating laser pulses to a material’s surface. They altered materials to make them repel water, attract water, and absorb great amounts of light – all without any type of coating. Now, Guo, Anatoliy Vorobyev, and Ranran Fang at University’s Institute of Optics, have advanced the research...
