文摘
- •
We simulate three compositions of silver-containing bioactive phosphate glass.
- •
We aim to understand how the structure controls the dissolution rate and bioactivity.
- •
Na and Ag bond to similar numbers of phosphate chains in the glass.
- •
The clustering of the modifier atoms should not affect the bioactivity substantially.
- •
The experimental changes in the dissolution are a complex function of structure.
