Non-Functionalized Colloidal Silica Nanospheres
-
Highly Monodisperse, CV< 3% for all sizes from 20 nm - 20 um.
-
Solid nanospheres by default with hollow core option available.
-
Roundness > 0.980, Density: 1.8 - 2.2 g/cm^3.
-
Sodium azide can be added as an antimicrobial agent upon request.
-
Prepared by the sol-gel process based on the Stöber method.
-
Surface chemistry: Hydroxyl-terminated (-OH) for hydrophilic.
-
Provided in Milli-Q water at difference concentrations 10 - 300 mg/ml (i.e. 1 - 30 % w/v) for non-functionalized colloidal silica nanospheres.
-
Can be also provided in anhydrous ethanol upon request.
-
Lifetime: At least 2 years from the date of product delivery.
-
These silicon dioxide nanoparticles can be easily surface-functionalized via chemical bond formation.
-
Our analytical-grade non-functionalized silica nanospheres can be widely utilized for scientific applications. For instance, 100 nm silicon dioxide (silica) nanoparticles have been frequently used for aggregation tests and colloidal behavior studies, and 1 μm non-functionalized silica nanoparticles are suitable for chemical deposition and other biomedical applications. Silica nanoparticles with an ultra-narrow size distribution are also frequently used as a size standard for many applications.
-
These silica nanospheres are ultra-stable in aqueous solutions at room temperature and can be easily adapted to common biological buffers like phosphate-buffered saline (PBS) or organic solvents like ethanol via repeated centrifugation and resuspension.

After several years of research and development, our synthesis of monodisperse silica nanoparticles has become a mature technology that enables us to precisely controls the particle size from batch to batch. Characterizations have been carried out using various precision instruments such as high-resolution transmission electron microscopy, field emission scanning electron microscopy, particle size analyzer, and ultraviolet–visiblespectroscopy. The series of monodisperse particles have high sphericity, strictly monodisperse particle size, small coefficient of variation and stable physical and chemical properties. Our silica nanoparticles have a nearly perfect sphericity and an extremely narrow particle size distribution. The nanoparticles with a CV value of 3.0% have extremely stable physicochemical properties, are easy to store, and have good stability. The surface of these spheres is rich in hydroxyl functional groups and is easy to functionalize. Applications of our silica nanoparticles include research and preparation of photonic crystals, synthesis of ordered structural materials, biomedical testing, catalytic carriers, high performance polymer additives, polymer nanocomposite fillers, preparation of advanced ceramics, chemical mechanical polishing.
