Let’s make things clear. Nano S
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
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
Reaction to Biofilm
Colloidal silver cannot be used with other beneficial agents and has a weak effect on the biofilm. Therefore, it does not do a sufficient job protecting enamel and balancing the oral biofilm by reducing acid. Nano Silver can be used at much lower concentrations and can penetrate biofilms with ease. It is modifiable to the outer coating of the oral biofilm. This helps it to latch onto and penetrate biofilms easier. It can release silver ions directly inside the biofilm and target acid.
