Nanotechnology is being applied in healthcare to help prevent, diagnose and treat illnesses.

Nanotechnology has already helped to create antimicrobial coatings that can minimise the spread of bacteria and viruses, reducing the risk of patient exposure. Furthermore, nanoscale filters can help to reduce pathogens in the air and liquids that patients are exposed to. Point-Of-Care and Lab-On-A-Chip devices can help detect disease earlier and without the need to send samples to be processed. Nanotechnology is also helping to create more effective drugs with novel means of delivery that help the drugs reach their intended target, which has particular benefits for cancer treatments.

Applications of nanotechnology are helping to dramatically improve healthcare and are ultimately making medicine more preventative. These applications are reducing the spread of pathogens, enabling doctors to detect diseases earlier or even before they have started to show symptoms and creating more efficient drugs that have fewer side-effects. Nanotechnology is therefore an indispensable tool in improving healthcare products  and making them more competitive.
