Abstract
Deciphering the identity of nanoparticles and biomolecules from their existences in a myriad of applications within the scientific community becomes vastly essential at times. However, given their tremendously minuscule sizes and precise locations within a system or subsystem, the identification of the various types often becomes increasingly difficult. We, in this project, have devised a novel technique to distinguish classes of such objects based on their placement over a uniquely designed nanostructured interface. Using an illuminated double-lined metasurface, on chip material-based optical sorting of certain Mie-ranged silica (SiO2), gold (Au) and chiral nanoparticles was performed based on the physical behaviors exhibited by them
