Lectin-functionalized chitosan nanoparticle-based biosensor for point-of-care detection of bacterial infections

The WHO estimates an average of 10 million deaths per year due to the increasing number of infections and the predominance of drug resistance. To improve clinical outcomes and contain the spread of infections, the development of newer diagnostic tools is imperative to reduce the time and cost involved to reach the farthest population. The current study focuses on the development of a point-of-care technology that uses crystal violet entrapped, lectin functionalized chitosan nanoparticles to detect the presence of clinically relevant bacterial infections.
