What Are Some Examples of Nanotechnology in Biomarker Detection?
Several examples illustrate the application of nanotechnology in the detection of cancer biomarkers:
Gold Nanoparticles: Functionalized gold nanoparticles can be used in colorimetric assays to detect specific biomarkers. They change color in the presence of the target biomarker, providing a simple and effective way to identify cancer. Quantum Dots: These semiconductor nanoparticles can be designed to emit light at specific wavelengths when they bind to cancer biomarkers, allowing for highly sensitive imaging techniques. Magnetic Nanoparticles: Magnetic nanoparticles can be used to isolate and concentrate biomarkers from complex biological samples, improving the accuracy of detection methods. Nanosensors: Devices incorporating nanomaterials can detect biomarkers in bodily fluids like blood or urine, offering non-invasive diagnostic options.
