What is the role of Nanotechnology in medical diagnostics? Nanotechnology is increasingly used in the field of diagnostics, imaging and targeted drug delivery system. Nanotechnology techniques have been applied to therapeutic purposes too. For instance, nanoparticle-based delivery system have been created to protect drugs from degradation, thereby reducing the required dose and dose frequency, improving patient comfort and convenience during treatment, and decreasing treatment costs. Nanotechnology based medical diagnosis techniques under development Gold nanoparticles to develop a quick diagnostic test for Covid-19. Silver-plated gold nanostars in a sensor to detect RNA molecules that are early indicators of cancer. Nano sized exosomes to check for biomarkers demonstrating pancreatic malignancy.
