Despite its importance, solvent dispersion poses several challenges:
Aggregation: Nanoparticles have a tendency to clump together, forming aggregates that are difficult to break apart. Solvent compatibility: Not all nanoparticles are compatible with all solvents, making it essential to choose the right combination. Stability: Achieving a stable dispersion that does not sediment over time can be difficult. Scale-up: Techniques effective at the laboratory scale may not always translate well to industrial-scale production.
