摘要

本文提出了一种利用双轴突产生的干涉图样进行纳米颗粒分选的新型光流体系统。利用密闭的贝塞尔光束，通过调节流速和激光功率，对200 nm和500 nm的聚苯乙烯纳米颗粒进行大规模同时分选。此外，利用离散干涉图将2 μm聚苯乙烯颗粒组装成二维阵列。该系统首先利用基于片上双轴的干涉模式，将分选和组装功能集成到一个芯片上。它在细菌和DNA分选和细胞组装方面具有很大的潜力。

Nanoparticles sorting and assembly based on double-axicon in an optofluidic chip

This paper presents a novel optofluidic system for nanoparticle sorting by using interference patterns generated through a double-axicon. The tightly confined Bessel beam is used to sort the 200-nm and 500-nm polystyrene nanoparticles massively and simultaneously by adjusting the flow rate and the laser power. Additionally, 2-μm polystyrene particles are assembled into a 2D array by utilizing the discrete interference pattern. This system first utilizes the interference patterns based on the on-chip double-axicon, and integrates the sorting and assembly abilities into a single chip. It has a great potential in bacterial and DNA sorting and cell assembly.
