Abstract
Beam me up, Scotty! Laser irradiation of Langmuir monolayers of gold nanoparticles (NPs) and elaidic acid led to dramatic reorganization that was dependent on the laser power (see picture, scale bar = 100 microm). Variable-temperature experiments indicate that localized surface heating in an extremely small temperature range, induced by the laser beam, causes ordering of the NPs.
摘要
把我传送上去，斯科蒂！用激光照射金纳米颗粒（NPs）和反油酸的朗缪尔单层膜会导致显著的重组，这种重组取决于激光功率（见图，比例尺 = 100微米）。变温实验表明，激光束在极小的温度范围内引起的局部表面加热会使纳米颗粒有序排列。
