Laser induced nanojet functionalization of two-dimensional materials for sensing and energy harvesting applications

The development of modern green technologies using micro- and nanostructuring is inextricably linked to the search for new approaches for non-invasive manipulation of matter at the sub-micron and even nanoscale. One approach is the use of laser radiation as a unique methodology, developed by humankind and not found in living nature. Today, laser radiation is used everywhere, from supermarkets to laser surgery. However, a key limitation is the finite focusing dimensions of the radiation, which amount to hundreds of nanometers. Lanafuseha exploited near-field effects for laser processing of materials, using the photonic nanojet technology. This novel processing technology was applied to 2D materials, as they are emerging and highly promising materials for extremely high-demand technological fields such as medicine, solar energy, and sensing. The implementation of the photonic nanojet technology is inextricably linked to the use of optical tweezers. Specifically, optical tweezers enable contactless capturing of microparticles, using only light as a “tweezer”, for subsequent use in super-focusing the processing laser radiation. This way, we are able to form the narrowest beams to date, for high-precision nanostructuring.
