Creating optical centrifuge for particle clearing and separation
Previously, conventional centrifuges that generate a centrifugal force to make particles run away along tangential direction, are used for particle separation and sorting [9], but these devices are generally bulky and requires electricity-powered. Apparently, the traditional technique is unsuitable for applications in microfluidic systems.
