    Reconfigurable Sorting of Nanoparticles on a Thermal Tuning Silicon Based Optofluidic Chip by Xiaofu Xu, Yuming Dong, Guanghui Wang, Wenxiang Jiao, Zhoufeng Ying, Ho-pui Ho, Xuping Zhang

    Published 2018-01-01

    We numerically demonstrate a scheme of optofluidic sorting of nanoparticles on a silicon-based lab-on-a-chip system, with reconfigurable and multilevel sorting size thresholds. Size-dependent sorting of nanoparticles originates from the size-dependent distribution of trapping potential wells, which...

    Optofluidic Switching of Nanoparticles Based on a WDM Tree Splitter by Wenxiang Jiao, Guanghui Wang, Zhoufeng Ying, Zhiwen Kang, Tianyu Sun, Ningmu Zou, Ho-pui Ho, Xuping Zhang

    Published 2016-01-01

    We demonstrate a silicon-based wavelength-division multiplexing (WDM) tree splitter for optofluidic switching of nanoparticles in a lab-on-a-chip or nanofluidic system. The gradient force and scattering force induced by the evanescent field can, respectively, lead to trapping and transportation of c...

    Controllable Droplet Generators by Light-Heat Energy Conversion for Selective Particle Encapsulation by Yilin Chen, Jianxin Yang, Jiayin Wu, Zongbao Li, Shaojing Liu, Zhibin Yan, Huiqing Zhong, Ruixue Zhou, Aiping Luo, Ho-Pui Ho, Sailing He, Lingling Shui, Xiaobo Xing

    Published 2020-01-01

    Water-in-oil droplet generation for object encapsulation is of increasing importance in biochemical reaction, drug diagnostics, and environmental science. Optofluidic technique is a powerful tool for manipulating mesoscopic particles and droplets within a continuous liquid phase. Here, we report a f...
