Publication number: 20100300978Abstract: A device for washing and isolating magnetic particles from a continuous fluid flow in at least one fluidic channel having an inlet at one end and an outlet at another end, said device comprising at least one magnetic source carrier arranged proximate to the at least one fluidic channel. The at least one magnetic source carrier is moveable between a first position and a second position. The at least one magnetic source carrier comprises at least one first magnetic source, wherein a movement of the at least one magnetic source carrier to the first position places the at least one first magnetic source at a first spatial location along the at least one fluidic channel such that said at least one first magnetic source generates a maxima magnetic field at said first spatial location that attracts the magnetic particles from the continuous fluid flow and assembles said magnetic particles at said first spatial location.Type: ApplicationFiled: September 19, 2007Publication date: December 2, 2010Applicant: AGENCY FOR SCIENCE, TECHNOLOGY AND RESEARCHInventors: Qasem Ramadan, Liang Zhu, Hongmiao Ji, Wen-Tso Liu

Patent number: 7160025Abstract: Microfluidics mixing apparatus and methods of using same are disclosed for mixing fluids using increasing centrifugal force as the fluids being mixed traverse a mixing channel. One inventive apparatus comprises a generally planar substrate having a top major surface and a bottom major surface generally parallel to the top major surface, and a cover plate over the top major surface. The substrate has at least one inlet port that routes fluid to the top major surface, and at least one outlet port for mixed fluid. The substrate comprises a mixing channel having a depth measured from the top surface and a width, the mixing channel adapted to route fluids to be mixed therein in laminar flow and in a substantially spiral flow pattern that is parallel to the top surface. Apparatus of the invention can mix fluids flowing serially, or two or more fluids entering the device from different feed channels.Type: GrantFiled: June 11, 2003Date of Patent: January 9, 2007Assignees: Agency for Science, Technology and Research, National University of SingaporeInventors: Hongmiao Ji, Victor Samper
