Reconfigurable Sorting of Nanoparticles on a Thermal Tuning Silicon Based Optofluidic Chip
Publicado 2018-01-01Enlace del recursoWe 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
Publicado 2016-01-01Enlace del recursoWe 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...
