摘要：

In this work, we investigate methods of fabricating a device for the optical actuation of nanopartides. To create the microfluidic channel, we pursued three fabrication methods: SU-8 to molded polydimethylsiloxane soft lithography, laser etching of glass, and deep reactive ion etching of fused silica. We measured the surface roughness of the etched sidewalls, and the laser power transmission through each device. We then measured the radiation pressure on 0.5-mu m particles in the best-performing fabricated device (etched fused silica) and in a square glass capillary. (C) 2020 Optical Society of America
