This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"By coupling gold nanoparticles with a film of liquid crystals, researchers have assembled a structure whose optical properties can be modulated plasmonically. Able to switch between reflective and transparent, this “photonic sandwich” could find applications as a controllable light filter or smart mirror. Under light of a certain color, electrons in plasmonic nanoparticles sway in unison, generating a distinct optical signature sensitive to the size and shape of the nanoparticles and their immediate environment. For that reason, plasmonic nanoparticles have been used as biological and chemical sensors. And because that quivering of electrons can generate heat, these tiny particles have been valuable in sizzling tumor cells away with better-than-surgical precision. Despite these advanced applications, researchers are just beginning to understand how photo-excited nanoparticles deliver heat to their surroundings..."
