A new technique invented at MIT can precisely measure the growth of many individual cells simultaneously. The advance holds promise for fast drug tests, offers new insights into growth variation across single cells within larger populations, and helps track the dynamic growth of cells to changing environmental conditions.
The technique, described in a paper published in Nature Biotechnology, uses an array of suspended microchannel resonators (SMR), a type of microfluidic device that measures the mass of individual cells as they flow through tiny channels. A novel design has increased throughput of the device by nearly two orders of magnitude, while retaining precision. The paper’s senior author, MIT professor Scott Manalis, and other researchers have been developing SMRs for nearly a decade.
