Silicon dioxide

Silicon dioxide (Silica) serves as the core of gold-coated silica nanoparticles, featuring a spherical structure enveloped in a layer of gold nanoparticles on its surface. This composition endows them with distinctive chemical and optical properties, rendering them highly desirable for various applications in medicine, batteries, catalysis, sensors, and spectroscopy. The silica component provides a large surface area, a non-porous nature, outstanding charge transport capabilities, and biocompatibility.
