Claim Text:
1. An apparatus for monodispersed microdroplet generation and trapping of a sample wherein the sample is in an aqueous solution, comprising: a microchip; a microfluidic flow channel in said microchip; a source of the sample in an aqueous solution, a source fluid and magnetic particles wherein the sample adheres to said magnetic particles, said source connected to said microfluidic flow channel, said source including a pressure source; a droplet maker that generates microdroplets containing the sample in an aqueous solution, said source fluid and said magnetic particles, said droplet maker connected to said microfluidic flow channel and connected to said source of the sample, said source fluid and said magnetic particles, wherein said droplet maker includes a T-junction connected to said microfluidic flow channel and connected to said source of the sample, said source fluid and said magnetic particles producing microdroplets containing the sample, said source fluid and said magnetic particles; a carrier fluid in said microfluidic flow channel, said carrier fluid introduced to said microfluidic flow channel by a source of carrier fluid, said source of carrier fluid including a pressure source; a trapping section in said microfluidic flow channel, said trapping section including magnets; and a valve system including a multiport valve, said multiport valve directly connected to said microfluidic flow channel and said multiport valve directly connected to said T-junction, and said multiport valve directly connected to said source of the sample in an aqueous solution, a source fluid and magnetic particles and said multiport valve directly connected to said carrier fluid, wherein said valve system controls flow of said carrier fluid and said microdroplets containing the sample, said source fluid and said magnetic particles that enables trapping of said microdroplets containing the sample, said source fluid and said magnetic particles in said trapping section.
