Colloidal Silver vs. Nano Silver

BIOCOMPATIBILITY

This means that it is safe to be used and will respond appropriately in certain conditions. Biocompatibility is dependent on two things: the size of the particle and what is used as a capping agent. First off, colloidal silver particles are made without a capping agent. This means that they fall apart easily. Second, colloidal silver particles are inconsistent in size. On the other hand, silver nanoparticles are capped with plant extract. This makes them more stable and nontoxic to human tissue. In addition, with advancements in technology, nanoparticles are more consistent in size.

STABILITY

Colloidal silver does not have the ability to stay stable in various conditions. This is because colloidal silver is made through using the physical electric model by running a current through silver wires. This results in a division of silver particles and ions that are without capping agents and unstable outside of water. Silver nanoparticles are stable because their plant-based capping agent keeps them from decomposing. And, they respond favorably to various environments such as salts and biomolecules.
