Fast Cell Sorting – on a Chip

A dime-sized microfluidic device harnesses acoustic waves to efficiently sort cells

Flow-cytometry based cell sorters aid in both medical diagnosis and biological studies, but commercial systems tend to be expensive (both to purchase and maintain), large, and complex. Moreover, according to Tony Jun Huang, professor of engineering science and mechanics, Pennsylvania State University, USA, they have been reported to significantly reduce cell viability, especially when sorting fragile or sensitive cells such as neurons, stem cells, and sperm cells.
