文摘
- •
Controlled synthesis of 2D arrays of silver nanoparticles embedded in silica.
- •
Assessing bio-available silver release using the green algae as bio-sensors.
- •
The Ag release can be controlled by the distance nanoparticles/dielectric surface.
- •
All the Ag released in solution is in the form of Ag+ ions.
- •
Toxicity comparable to similar concentrations of Ag+ ions released from AgNO3.
