Abstract
Asymmetric branched gold nanoparticles are obtained using for the first time in the seed-growth approach a zwitterionic surfactant, laurylsulfobetaine, whose concentration in the growth solution allows to control both the length to base-width ratio of the branches and the LSPR position, that can be tuned in the 700-1100 nm near infrared range.
摘要
首次在种子生长法中使用两性离子表面活性剂月桂基磺基甜菜碱获得了不对称支化金纳米粒子，其在生长溶液中的浓度可以控制支的长度与基底宽度的比例以及 LSPR 位置，后者可以在 700-1100nm 的近红外范围内进行调节。
