What are Some Key Applications of Nanotechnology in Diagnostics?
1. Cancer Detection: Nanoparticles can be used to identify cancer biomarkers in blood or tissue samples. For instance, *magnetic nanoparticles* can isolate and concentrate cancer cells from a blood sample, making it easier to detect the presence of cancer at an early stage.
2. Infectious Disease Monitoring: Nanotechnology can accelerate the detection of pathogens. For example, *biosensors* based on carbon nanotubes can rapidly identify viral or bacterial DNA, enabling quick diagnosis of diseases like COVID-19, tuberculosis, and influenza.
3. Cardiovascular Disease: Nanoparticles can help in the early detection of cardiovascular diseases by identifying biomarkers like troponin in blood. This early detection is crucial for timely intervention and treatment.
