Gas-phase Scanning Mobility Particle Sizer for Virus-like Particles


Due to the outbreak of COVID-19, the development of vaccines is an urgent task, and the demands of analyzing the physical characterization of viruses and their derivatives rapidly are increased. Conventional methods for size and concentration analysis of viruses and their derivatives, such as polymerase chain reaction (PCR) and electron microscopy, are costly and time-consuming. NML has developed the gas-phase scanning mobility particle sizer (SMPS), which can provide size distribution with the precision from nanometer to sub-nanometer. Through this technique, the analysis of virus-like particles (VLPs) can be completed in less than an hour.
