Solvent assisted size effect on AuNPs and significant inhibition on K562 cells.

Herein, the synthesis and characterization of ideal size (∼10 and 40 nm, in diameter) AuNPs (gold nanoparticles) were reported. Two different organic solvents such as DMF (dimethyl formamide) and NMPL (-methyl-2-pyrrolidone) were used to synthesize AuNPs along with agents reducing agents such as NaBH (sodium borohydrate) and NaCHO (sodium citrate). The combination of [(HAuCl)-(DMF)-(NaBH)] gives AuNPs with an avg.
