{"cited_by_count":161631,"description":"This cluster of papers focuses on the enhancement and applications of photonic nanojets, a phenomenon that allows for subwavelength imaging and manipulation of light at the nanoscale. The research covers topics such as near-field optical microscopy, super-resolution imaging, microsphere-assisted techniques, scanning probe microscopy, and the use of dielectric microspheres for various optical applications.","display_name":"Near-Field Optical
