Why Choose Silica Nanomaterials?

Silicon dioxide nanomaterials include various structures such as solid silicon dioxide nanoparticles, mesoporous silicon dioxide nanoparticles (MSN), and hollow silicon dioxide spheres, which have a series of remarkable advantages:

• Excellent versatility: Silicon dioxide can be designed in various forms (spheres, rods, tubes, films) with precise control over size, porosity, and surface chemistry.
• High specific surface area and adjustable pores: Especially mesoporous silica, with incredible high surface area and pore volume, makes it an ideal choice for adsorption, catalysis, and high-capacity loading of various active agents. The aperture can be precisely adjusted from 2nm to 50nm.
• Biocompatibility and low toxicity: Amorphous silica is generally considered biocompatible and non-toxic, making it suitable for biomedical applications such as drug delivery and imaging.
• Chemical and thermal stability: Silicon dioxide nanomaterials have excellent chemical inertness and thermal stability, enabling them to withstand harsh environments and various processing conditions.
