What is Nano Silica? Silicon Dioxide Nanoparticles also known by silica nanoparticles and nano-silica appear in the form white powder.
P-type silica particles are divided according to the structure of nanometers. P-type silica particles are distinguished by their large number of nanopores. Their porosity is 0.61 mL/g and have higher UV reflectivity than S type particles. 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 acid group type. It has hydrophilic water absorption rates that exceed 5 times their own.
Silica nanoparticles have many uses. They are used as additives in rubber and plastic production, reinforced fillers for concrete and other building materials, and as a stable, nontoxic platform for biomedical purposes such as drug delivery or therapeutic diagnostics.

What is Silica?
Silicon (or simply silicon) is one of the many chemical elements found in the earth’s crust. It can be found in silicate (SiO4) or silicon dioxide (silica and SiO2).
It is common to use silicon in industry. The oxide form 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.
Silica can be found in two forms, crystalline or amorphous. Although they share the same molecular structure, these two basic forms of silica have very different structural arrangements. Amorphous silica exhibits a different lattice arrangement while crystalline silica displays a regular one. 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 silica. Porosils are porous crystalline silicon, which is also known as porous silica. All porosils come from synthetic materials.
Mesoporous silica and silica are excellent candidates for controlled drug delivery because of their unique properties. These include high surface area, large pores volume, adjustable size, good chemical and thermal stability, and high pore sizes. Amorphous silicon can be classified into three groups: natural forms and byproducts of power stations or metallurgical processes. 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 is used in dental fillers, dental implants, dietary supplements and catheters.

What uses is nanosilica?
Nano silica can be used to modify cement concrete’s dispersion, plasticity and temperature. It gives it impermeability, enhanced permeability, frost resistance and reduces hydration heat.
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 material. Additionally, it can be used in a variety of resin engineering material; High-quality FRP packing that is corrosion-resistant.
It is used to cement seal oil wells and as reinforcement material for 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 occupational exposures to crystalline silicona can lead to silicosis in workers. This is a fibrotic lung condition that can also be associated with lung cancers, emphysema, tuberculosis and other diseases.
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 those that may affect the immune system.
