Choosing the right reducing agent depends on several factors:
Desired Particle Size and Shape: For smaller particles, a strong reducing agent like sodium borohydride might be used. For specific shapes, combinations of reducing and capping agents might be required. Reaction Environment: The pH, temperature, and solvent used in the reaction can all influence the effectiveness of the reducing agent. Application Requirements: If the nanoparticles are intended for biological applications, biocompatible reducing agents like ascorbic acid or plant extracts might be preferred.
