Advancements in nanotrap technology for the prevention, diagnosis and treatment of infectious diseases

Nanotraps are particles designed to capture and concentrate target molecules and have numerous applications in infectious diseases. This review outlines how nanotrap technologies may improve the detection and treatment of bacterial and viral pathogens, including Mycobacterium tuberculosis, Borrelia burgdorferi, Yersinia pestis, HIV, SARS-CoV-2, and others. Nanotraps can enhance the sensitivity of diagnostic tools and support treatment by neutralizing bacterial toxins, capturing inflammatory mediators, and preserving viral proteins for detection. Nanotraps have also been investigated for vaccine development. While results from in vitro and in vivo models are encouraging, there is significant room for further research regarding safety and other unexplored applications of these technologies. Nanotraps offer a flexible platform with the potential to improve how we diagnose and manage a multitude of infectious diseases.
