Quantum Dots: These are semiconductor nanoparticles that can be used for imaging purposes. They emit light when excited and can be used to label cells and tissues, making them useful in detecting abnormalities. Gold Nanoparticles: These can be functionalized with specific antibodies or ligands to bind to disease markers. They are particularly useful in colorimetric assays, where a color change indicates the presence of a disease marker. Nanosensors: These are sensors at the nanoscale that can detect biological molecules at very low concentrations. They are highly sensitive and can provide real-time monitoring of disease markers. Nanotubes: Carbon nanotubes and other nanostructures can be used to create highly sensitive detection devices. They have unique electrical properties that make them suitable for various sensing applications.
