Silicon Dioxide Nanoparticles Description and Specifications
Silicon Dioxide (SiO2) is a molecule made from Silicon and Oxygen, sometimes known as Silica, and the components are held together by a covalent connection. It is one of the sand’s constituents and is present naturally in Quartz. It is typically white or colourless, insoluble in water or ethanol. It produces the silicate family by combining with minerals. Silicon Dioxide nanoparticles or Silica nanoparticles as a substrate are most common for proteins and enzymes and as a modified surface to immobilize cells and tissue. Surrounding a central Silica core, the nanoparticles have a unique hexagonal “waffle-iron” crystal structure. The negatively-charged surface of the particles is naturally attracted to positively-charged DNA molecules. The consumption of Silicon Dioxide as a natural mineral necessary for life on earth is vast. The nanostructured Silica with unique geometric properties forms biomaterials conjugates with various hybrid nanomaterials. It helps produce innovative results for sensing and imaging DNA.
The Silicon Dioxide nanopowder, also known as Silica nanoparticles or nano-silica, is the foundation for much biological research. According to their structure, the classification of nano-silica particles includes P-type or S-type. Compared to the S-type, the P-type particles feature numerous nanopores with a pore rate of 0.61 ml/g and higher UV reflectivity. The latter also has a significantly smaller surface area.
Reaction
Silicon Dioxide nanopowder does not react with water and is acid-resistant. The substance’s chemical formula is SiO2. Silicon oxide, the group of acidic glass-forming oxides, interacts with alkalis and basic oxides as temperature rises, generating a supersonic fusion, indicating that glass is an excellent dielectric. The Chemical Co-Precipitation technique creates the suspension of nanoparticles. At ambient temperature, these Silica nanoparticles are ultra-stable in aqueous solutions and may be easily tailored to typical biological buffers such as phosphate-buffered saline (PBS).
Analysis
Our analytical-grade non-functionalized SiO2 nanoparticles are suitable for many scientific applications. For example, 100 nm Silicon Dioxide (Silica) nanoparticles are standard for aggregation tests and colloidal behaviour research. In contrast, non-functionalized Silica nanoparticles are excellent for chemical deposition and other biological applications. Many applications rely on Silica nanoparticles with ultra-narrow size distributions as a size reference.
