Improving PDI involves optimizing the synthesis and processing protocols:
1. Controlled Synthesis: Techniques such as microfluidics can provide better control over particle formation. 2. Post-Synthesis Processing: Methods like centrifugation and filtration can be used to separate particles by size, thus narrowing the distribution. 3. Stabilizing Agents: Adding surfactants or polymers can prevent aggregation, leading to a more uniform size distribution.
