Application
以四辛基溴化铵 (TOAB) 为相转移剂，采用两相（有机-水相）烷基硫醇稳定的金纳米颗粒合成法，将四氯金酸金从水相转移到有机相。它还用于制备 TOAB 封端金纳米颗粒，与巯基封端纳米颗粒相比，显示出明确的等离子体吸收。
General description
四辛基溴化铵是一种有机表面包覆剂，常用于控制纳米颗粒合成过程中的尺寸和形状。

Impact on health by nanomaterials has become a public concern with the great advances of nanomaterials for various applications. Surface coating agents are an integral part of nanoparticles, but not enough attention has been paid during toxicity tests of nanoparticles.

Engineered nanoparticles could trigger inflammatory responses and potentiate a desired innate immune response for efficient immunotherapy. Here we report size-dependent activation of innate immune signaling pathways by gold (Au) nanoparticles. The ultrasmall-size (<10 nm) Au nanoparticles preferentially activate the NLRP3

Revealing structural isomerism in nanoparticles using single-crystal X-ray crystallography remains a largely unresolved task, although it has been theoretically predicted with some experimental clues. Here we report a pair of structural isomers, Au38T and Au38Q, as evidenced using electrospray ionization
