What is Nano Silica? Silicon Dioxide Nanoparticles also known by silica nanoparticles and nano-silica appear in the form white powder.
The structure of nanometer-sized silica particles allows for the division into P-type (or S-type) types. P-type silica particles have more nanopores than S-type, which has a porosity 0.61 mL/g and a higher UV reflection. They also have a very small surface area.
Nano silica features a light volume, fluffy bulk density, less than 0.15-0.2g/cm3, an area specific of more than 500m2/g, high chemical activity, and a large surface area.
The surface of nano silica contains an OH bond. This makes it a silicate group type of acid oxide. The water absorption rate is greater than 5 times that of silicate acid.
Silica nanoparticles have many uses. They are used as additives in rubber and plastic production, reinforced fillers for concrete and other building components, and as a platform for biomedical applications like drug delivery and therapeutic diagnosis.

What is Silica?
Silicon (or simply silicon) is one of the many chemical elements found in the earth’s crust. Its oxide forms include silicate (SiO4), and silicon dioxide [silica, SiO2].
It is common to use silicon in industry. The oxide form of silicon is often used in biomedical and industrial applications. SiNPs are rare because of their unique properties. These include ease of synthesis and surface modification, strong mechanical property, and relatively inert chemical structure. They have been used in biological materials for many decades.
There are two basic types of Silica: crystallized and amorphous. Although they share the same molecular structure, these two basic forms of silica have very different structural arrangements. Crystalline silica features a regular lattice arrangement while amorphous is more irregular. Crystalline silica can be found in many forms. Alpha-quartz is the most well-known, and can be transformed by heating to b –quartz or squamous, as well as quartzite. Porosils are porous crystalline silicon, which is also known as porous silica. All porosils come from synthetic materials.
Mesoporous silica and silica are great candidates for controlled drug releases because of their rare properties. These include high surface area and large pore volumes, adjustable pores, good chemical and thermal stability, and high pore size. There are three main types of amorphous silicon: natural, byproducts, and synthetic. Amorphous silica has been considered a promising candidate to carry genes and perform molecular imaging. This is due to its highly adjustable biocompatibility as well as stability. It can be used in dental fillers and dietary supplements as well as catheters, implants, and catheters.

What uses is nanosilica?
Nano silica can be used to modify cement concrete’s dispersion, plasticity, and thus increase its impermeability, enhanced permeability, frost resistance and reduce hydration heat. It also prolongs the service life.
It can be used as a vitrification agent, strengthening agent, adhesive, and glue of ceramics, enamels and glazes. It is also used as a high thermal binder in engineering-grade and refractories.
Use nanocomposite materials modifier as an inorganic adhesive at high temperature. Also used as an additive to inorganic composite materials for strengthening, molding and filling of rubber/polymer substances. Additionally, it can be used in a variety of resin engineering material; High-quality FRP packing that is corrosion-resistant.
Used for cement seals of oil wells and as reinforcement material under-ground engineering.
Use for special purposes, including lamp paint, lubricating oil, thickener or steel dehydrogenate and inner wall paint sensitive material. For solar cells and power cell energy storage.

Is nano-silica toxic?
Exposed to silica, particularly crystalline, has been extensively researched.
Studies have shown that workers are exposed to crystalline silicona at work, which can lead to silicosis. This is a fibrotic lung condition that can also be caused by other diseases such as lung cancer, emphysema, or tuberculosis.
Amorphous silica used to be considered less toxic than crystalline. Recent research has shown that SNPs that are amorphous have toxicity levels similar to crystalline particles. SiNPs’ physicochemical and crystallinity also produce different levels of toxicity in vitro as well as in vivo. Consider safety and possible adverse effects, especially for those that affect the immune system.
