(Nanowerk News) Researchers from Bochum and Texas have discovered why carbon nanotubes fluoresce when they bind to certain molecules. Carbon nanotubes are considered promising biosensors that could be ...
The biosensor uses "capture probes" called aptamers, which are single strands of DNA that bind to virus proteins, flagging them. The team's big challenge was finding a way to get these aptamers to ...
SPR biosensors measure molecular interactions in real time. Several other methodologies determine affinity of complex formation, such as ELISA, analytical ultracentrifugation, equilibrium ...
WHO noted that prequalified tests can now be prioritized in pooled procurement mechanisms, which help lower prices, stabilize ...
WHO has prequalified two rapid COVID-19 antigen tests, confirming their safety and quality and expanding access to fast, ...
WHO said the decision builds on earlier emergency approvals and reflects the continued need for affordable, fast COVID-19 testing even after the pandemic’s emergency phase.
