Key Features of Silicon Oxide Nanopowder (SiO₂ NPs):
-
Chemical Composition and Structure: Composed of silicon and oxygen atoms (SiO₂), these nanoparticles can exist in various structural forms depending on the synthesis method. They can be amorphous, lacking a long-range ordered structure, or crystalline, exhibiting specific arrangements like quartz or cristobalite. At the nanoscale, the surface often presents a significant degree of disorder and a high concentration of reactive silanol (Si-OH) groups. Furthermore, they can be synthesized with different porosities (P-type, containing nanopores) or as relatively non-porous, spherical particles (S-type).
-
Ultra-Fine Particle Size and High Surface Area: With diameters typically ranging from 5 to 100 nanometers, silicon oxide nanoparticles possess an exceptionally high surface area to volume ratio. This characteristic is fundamental to many of their applications, as it significantly enhances their interaction with surrounding materials, leading to improved adsorption capacities, catalytic activity when used as supports, and reinforcement effects in composites. The specific surface area can vary widely, from 25 to over 600 square meters per gram, depending on the precise size and porosity of the nanoparticles.
-
Chemical Inertness and Stability: Silicon dioxide is generally a chemically stable compound, exhibiting resistance to many chemical reactions. This inertness makes SiO₂ NPs suitable for applications where they need to maintain their structural integrity in various environments. They are also thermally stable at high temperatures, further broadening their applicability. However, they can react with strong bases (alkalis) and hydrofluoric acid.

Key Features:
- High Purity Gold: The product should be made with a high percentage of pure gold to minimize the presence of other metals or contaminants.
- Nanoparticle Size Control: The gold nanoparticles are typically within a specific size range (e.g., 5-100 nm) claimed to be optimal for interaction with the body.
- Pure Solvent: The nanoparticles are usually suspended in ultrapure water.
- Minimal or "Food-Grade" Stabilizers: If stabilizers are used to prevent aggregation, they may be claimed to be minimal and safe for ingestion (e.g., citric acid in very low concentrations).
- Specific Concentration: The concentration of gold is usually low and specified in parts per million (ppm) or micrograms per liter (µg/L).
- Pleasant or Neutral Taste: Edible formulations may be processed to have a less metallic or no noticeable taste.
- Packaged for Ingestion: Sold in bottles or other containers suitable for oral consumption, with clear dosage instructions.
