Abstract

Bacteria and nanoparticle sorting are of paramount importance both in biomedical and biophysical studies. Conventional optical chromatography and holographic optical tweezers can sort particles in a fluidic environment. However, sizes of particles limit in the micro-scale and the sorting resolution is low. Here, we demonstrate sorting of E. coli, cryptosporidium and 100-nm polystyrene nanoparticles and trapping of 300-nm polystyrene nanoparticles in the microchannel using distinct interference patterns. This optofluidic system provides new insight of the purification, sorting and quantification of bacteria and viruses in serum samples [1, 2].
