• Sommario/riassunto: 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, optics and information technology. One particularly promising application is the microfluidic synthesis of polymer particles with precisely controlled dimensions, and a variety of shapes, morphologies and compositions. Written as a comprehensive introduction for scientists and engineers working in micr
