How Does Nanotechnology Improve Tumor Marker Detection?
Traditional methods of detecting tumor markers can be time-consuming and may lack sensitivity. Nanotechnology enhances the detection process by utilizing nanoparticles, quantum dots, and nanosensors. These nanomaterials can be engineered to bind specifically to tumor markers, allowing for highly sensitive and specific detection even at very low concentrations. For example, gold nanoparticles can be functionalized with antibodies specific to a tumor marker, leading to a colorimetric change that can be easily observed. Similarly, quantum dots can be used to provide fluorescent signals that are much brighter and more stable than traditional dyes.
