What Role Does Nanotechnology Play in Diagnostic Techniques?
Nanotechnology has significantly improved diagnostic techniques by enabling the development of highly sensitive and specific biosensors and imaging agents. Quantum dots, gold nanoparticles, and magnetic nanoparticles are examples of nanomaterials used in diagnostics. These materials can be conjugated with biomolecules, such as antibodies or DNA, to create probes that can detect minute quantities of biomarkers associated with diseases. Additionally, nanotechnology-based imaging techniques, such as nanoparticle-enhanced MRI and fluorescence imaging, provide high-resolution images of biological structures and processes, aiding in early disease detection and monitoring.
