We study plasmon-exciton interaction by using topological singularities to spatially confine, selectively deliver, cotrap and optically probe colloidal semiconductor and plasmonic nanoparticles. The interaction is monitored in a single quantum system in the bulk of a liquid crystal medium where

A thermo-responsive membrane embedding with the binary mixture of 36% cholesteryl oleyl carbonate (COC) and 64% cholesteryl nonanoate (CN) was successfully developed to achieve a rate-controlled and time-controlled drug release in response to the skin temperature (i.e., 32 degrees C)

Starting with Gauss and Kelvin, knots in fields were postulated to behave like particles, but experimentally they were found only as transient features or required complex boundary conditions to exist and could not self-assemble into three-dimensional crystals. We introduce energetically
