Engineers at MIT have developed a technique that allows accurate measurement of weight particles, viruses, nanomaterials to a millionth of a trillionth of a gram. The new technology is based on the technique developed by professor Scott Manalis at MIT. The system measures the mass of the particles as they flow through a very narrow channel. The engineers shrunk the size of the entire system and achieved the resolution to 0.85 attograms and have claimed that it's 30x improvement than the previous generation of the device.


The technique will be very useful in measuring the weight of small viruses, extracellular vesicles and also engineered nanoparticles. Check out the details of the research on the source link below.
