A safe, fast and cheap testing method that uses magnetic nanoparticles to detect viruses in both clinical and wastewater samples has been developed by KAUST researchers. The centrifuge-free approach is compatible with magnetic bead-based automated systems that are already used to process hundreds of samples.

"Our silica magnetic nanoparticle-based workflow can be assembled from scratch by any researcher," says lead author Gerardo Ramos-Mandujano. "It rivals commercial viral-RNA extraction kits while lowering the risk of handling potentially infectious samples."

To diagnose COVID-19, clinicians extract SARS-CoV-2 viral RNA from different types of clinical samples, such ...
