Abstract
Monolayers of gold nanostars (GNS) are grafted on mercaptopropyltrimethoxysilane-coated glass slides. In the formed monolayers the localized surface plasmon resonance of GNS can be tuned in the 700-1100 nm range. Upon laser excitation of the nearIR LSPR an efficient photothermal response is observed, inducing local hyperthermia and efficient killing of Staphylococcus aureus biofilms.
摘要
金纳米星（GNS）的单层被接枝到巯丙基三甲氧基硅烷涂覆的载玻片上。在形成的单层中，GNS 的局域表面等离激元共振可以在 700-1100nm 范围内进行调节。当近红外 LSPR 被激光激发时，会观察到有效的光热响应，从而诱导局部过热并有效杀死金黄色葡萄球菌生物膜。
