University of Leeds researchers have observed for the first time how HIV and Ebola viruses attach to cells to spread infection. The findings offer a new way of treating such viruses: instead of destroying the pathogens, introduce a block on how they interact with cells. They used ‘quantum dots’ that mimicked the shape of the viruses and acted as technological stand-ins in experiments to reveal how they bind to cells.
Quantum dots are fluorescent crystals in which the colour of the emitted light is dependent on the size of the crystal – one of several properties that has led to them becoming the most desirable component for the...
