Multi-shaped Gold Nanoparticles Synthesized Using an Amino-terminated Poly(ethylene oxide)-Poly(propylene oxide) Block Copolymer in Aqueous Solutions
Multi-shaped gold nanoparticles such as mushroom-like particles, dendritic particles, starlike particles, elongated particles, and spherical particles were synthesized through the reduction of tetrachloroaurate(III) ions ([AuCl4](-)) by an amino-terminated poly(ethylene oxide) poly(propylene oxide) block copolymer (SURFONAMINE L-207; CH3[OCH2CH2](33)[OCH2-CH(CH3)](10)NH2) in aqueous solutions.
