Silicon Dioxide Nanoparticles: What Type of applications are they involved in?

Silicon Dioxide Nanoparticles, also known as silica Nanoparticles, are capable for biological applications owing to their excellent biocompatibility, low toxicity, thermal stability, facile synthetic route, and large-scale synthetic accessibility.

The particle size, porosity, and shape can be accurately manipulated, enabling the Silica Nanoparticles permit their control of surface chemistry to accomplish drug loading, good dispensability, as well as site-specific targeting.

If these properties combined and developed appropriately, make silicon nanoparticles a podium for biomedical imaging, detecting therapeutic delivery, monitoring, and ablative therapies. With the design of different dopants, surface functional groups, as assembly techniques, multifunctional nanoparticles developed with the theranostic applications. Silica Nanoparticles are also widely applied in other areas such as energy source, electronic, sensor, and catalysis purposes.

Properties of Silica Nanoparticles

Silica nanoparticles are divided into two categories based on their categories i.e. P-type and S-type. The previous nanoparticles are characterized by many nanopores featuring a pore rate of 0.61 ml/g and the latter nanoparticles have a relatively smaller surface area. In distinction to the S-type, the P-type silica nanoparticles patent a higher ultraviolet reflectivity.

The Silica Nanoparticles are fabricated via the condensation of silanes to form nanoparticles composed of an amorphous arrangement of silicon and oxygen. The nanoparticles are monodispere with high steadiness, and the nanoparticles have the narrow size distributions. The density of the nanoparticles is approximately two g/cm- 3 slightly affected by the degree of condensation. The refractive index of nanoparticles is determined to be 1.43. The nanoparticles are well dispersed in polar solvents like water and ethanol.
