Silica Particles

Silica, or silicon dioxide (SiO2), particles feature controllable size, large surface area, and easy surface modification via silanol groups. They can be nonporous, mesoporous, hollow, or core-shell structured. Surfaces can be modified with groups like carboxylate or amine for bonding. Silica is applied in protein separation, drug delivery, imaging, and more. It has low water solubility that increases with high or low pH.

Key aspects of silica particles:

• Properties: Silica particles possess a controllable particle size, a large specific surface area, and an easily modified surface due to silanol groups (Si-OH). They also have good chemical properties, thermal stability, and biocompatibility.
• Types: Silica nanoparticles can be nonporous, mesoporous (MSN), hollow mesoporous (HMSN), or core-shell structured.
• Synthesis: They can be synthesized using methods like the Stöber method and the microemulsion method, resulting in sizes ranging from 10 to 500 nm. Adjusting reaction conditions can easily tune particle sizes.
• Surface Modification: The surface of silica particles can be modified with various functional groups like carboxylate, amine, or octadecyl, which allows for covalent bonding with other molecules.
• Applications: Silica particles are used in protein adsorption and separation, nucleic acid detection and purification, drug and gene delivery, imaging, and as theranostic platforms.
• Solubility: Silica has low solubility in water, but the solubility increases at pH values above 8 and below 3.
• Dispersibility: Silica particles can be dispersed in polar solvents such as water and ethanol.
