Abstract
A biological particle capturing and retrieving system includes a capturing device including a substrate, an isolating layer and a driving unit, and a retrieving device including a micropipette. The isolating layer includes a top surface, multiple pores, and multiple fluidic grooves indented from the top surface, arranged in a herringbone pattern, and each having a bottom surface. The pores are formed in the bottom surfaces of the fluidic grooves, and each capture a biological particle in a liquid sample. The driving unit drives the liquid sample to flow by electrowetting through the pores. The micropipette has a carrier coated with a biological particle-binding material binding with the biological particle received in a corresponding pore.
