Microfluidics deals with the behavior, precise control and manipulation of microliter and nanoliter volumes of fluids.
Manu Prakash, grad student from the M.I.T.’s Center for Bits and Atoms had a 100% presentation on microfluidics at the SciFoo Camp, 2007. The small audience (I remember Jeff Hawkins and Lincoln Stein amongst others) was really amazed by the happenings in the microbubble world.
For me the most interesting part of the presentation was on the biological applications in the pipeline, one of them is the option of packing one cell into one bubble, thereby producing a one cell delivery system and a cell counting method.
