Abstract Gold nanostars (GNSs), were synthesized and coated with N-(3-aminopropyl) methacrylamide hydrochloride (PA) in order to functionalize their surfaces by amine groups as well as to investigate the production of singlet oxygen (1O2). The singlet oxygen production by the large sized GNSs with multi-tips seems to be superior to that by the small GNSs with fewer tips. In combination with methylene blue (MB+), the functionalized GNSs could increase the singlet oxygen production of MB+ after 1 h of LED750 irradiation. Only PA-coated GNSs could catalyze the oxidation reaction of 5-aminolevulinic acid (ALA) for the singlet oxygen production.

用于单线态氧生产的金纳米星的合成和功能化

摘要 金纳米星 (GNSs) 被合成并用 N-(3-氨基丙基) 甲基丙烯酰胺盐酸盐 (PA) 包覆，以通过胺基对其表面进行功能化，并研究单线态氧 (1O2) 的产生。具有多尖端的大型 GNS 产生的单线态氧似乎优于具有较少尖端的小型 GNS。与亚甲蓝 (MB+) 结合，功能化的 GNS 可以在 LED750 照射 1 小时后增加 MB+ 的单线态氧产量。只有 PA 包覆的 GNS 才能催化 5-氨基乙酰丙酸 (ALA) 的氧化反应以产生单线态氧。
