Nanotechnology is crucial in diagnostics due to its potential to revolutionize how diseases are detected and monitored. Traditional diagnostic methods often lack the sensitivity to detect low levels of biomarkers or require invasive procedures. In contrast, nanotechnology offers minimally invasive, highly sensitive, and rapid diagnostic options. For instance, nanoparticles can be engineered to target specific biomolecules, enhancing the detection of diseases like cancer, cardiovascular diseases, and infectious diseases at very early stages.
