One-step synthesis of cellooligomer-conjugated gold nanoparticles in a water-in-oil emulsion system and their application in biological sensing.
本研究在由80% NMMO/20%水和十二烷组成的油包水乳液(反向胶束)中,以双(2-乙基己基)磺基琥珀酸钠(AOT)为阴离子表面活性剂,一步合成了单分散金纳米颗粒(GNP)。将聚合度为6或15的纤维素寡糖(βGlc6或βGlc15)在还原端标记硫代氨基脲(TSC)并溶于NMMO水相,在NMMO介导的金离子还原过程中原位偶联到GNP...
