Paragraph starter

The selection of solvent during material synthesis is a critical production parameter that significantly influences the resulting material's properties. For instance, research on gold nanoparticle synthesis demonstrated that using toluene as a solvent led to superior particle dispersity and a narrower size distribution compared to other solvents, which directly translated to improved performance in their intended application as SERS substrates (Hao et al., 2022). This underscores the importance of carefully controlling synthesis conditions to achieve desired material characteristics for optimal product functionality.
