General description

Our monodisperse non-porous silica particles have a uniform particle size of 40 µm and a narrow size distribution. Furthermore, these particles are non-porous, meaning they do not contain any internal void spaces. This feature renders their surfaces impermeable to fluids and gases. Additionally, their monodispersity contributes to excellent dispersion properties, allowing them to disperse evenly and maintain stability in a range of solvents, suspensions, or matrices.

Application

Monodispersed non-porous silica particles find use in various applications such as fillers or additives in composites, coatings, paints, and polymers to enhance mechanical properties or provide unique functionalities. Additionally, these particles find utility in diagnostics, drug delivery systems, sensors, catalysis, and environmental remediation. Their tailored size, uniformity, and stable surfaces contribute to their effectiveness in these applications. The silica particle surface exhibits a highly modifiable chemistry that allows for easy passive functionalization with a variety of biomolecules. The silica particles can also be modified with different functional groups, which can serve as a scaffold for the covalent attachment of biological components such as dextran, antibodies, DNA, or peptides.,
