Scientists from ITMO University have developed a production method for bio-integrated optical nanomaterials based on Mie-resonant silicon nanoparticles. The nanoparticles used in the work are covered by biopolymer shells and can be controlled by heat. With light irradiation, the particles change their shape and color. The discovery is poised to support nanophotonic and nanomedicine applications and the development of noninvasive biosensors, signal systems, and nontoxic dyes.
Though the issue of controlled nanomaterials is resolved, existing systems that rely on them can be toxic to living organisms, which limits the scope of their application in medicine and biology. The ITMO researchers’ material is fully biocompatible, with…READ MORE
