Researchers develop ‘next-generation vaccine platform’ against SARS-CoV-2 The etiological agent of coronavirus disease 2019 (COVID-19), the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), transmits efficiently from human-to-human. Since the virus was first detected in December 2019 in Wuhan, China, new variants – with mutations at the virus’s spike protein – have emerged, resulting in heightened transmissibility. With no targeted and effective antiviral treatment options currently available, mass vaccinations remain our best bet at turning the tide of the COVID-19 pand...

Using Dynamic Light Scattering (DLS) to Analyze Virus Particles Conventional visual techniques of detecting virus particles in solution provide a glimpse of an extremely small sampling volume, while the method of particle analysis employing dynamic light scattering generates an ensemble average of particles inside the solutions. Virus particles incubated in the laboratory pose an issue, as they need to be grown inside cells in a media containing albumin and additional small proteins, like those inside Fetal Bovine Serum (FBS) or Minimum Essential Media (MEM) solutions. When v...
