Descrição

Descrição geral

Our hollow silica nanoparticles are precisely engineered spherical particles of silicon dioxide. These particles have a uniform particle size of 500 nm comprised of a porous silica shell, with an average pore size of 20 Å, that surrounds the central hollow cavity. The structure and design of these nanoparticles play a vital role in determining their unique physical characteristics. These properties include low density, a large specific surface area, low dielectric constant, low electrical and thermal conductivity, as well as abnormal light scattering behavior.

Aplicação

Hollow silica nanoparticles are extensively studied for their applications across multiple fields, including drug delivery, catalysis, thermal insulation, and functional coatings. For example, the combination of their low density, significant surface area, easily modifiable surface, and low toxicity makes them highly appealing for loading drug molecules or catalysts onto their surfaces.
