An innovative device studies gold nanoparticles in depth

Artists have used gold nanoparticles for centuries, because they produce vibrant colors when sunlight hits them. Their unique optical-electronics properties have put gold nanoparticles at the center of research, solar cells, sensors, chemotherapy, drug delivery, biological and medical applications, and electronic conductors. The properties of gold nanoparticles can be tuned by changing their size, shape, surface chemistry etc., but controlling these aspects is difficult.
