Microfluidic reactors for polymer particles
The manipulation of fluids in channels with dimensions in the range from tens to hundreds of micrometers - microfluidics - has recently emerged as a new field of science and technology. Microfluidics has applications spanning analytical chemistry, organic and inorganic synthesis, cell biology, optic...
