The Nanodiagnostics refers to the use of nanotechnology for the detection, diagnosis, and monitoring of diseases and medical conditions at the nanoscale. By utilizing nanomaterials such as nanoparticles, nanotubes, and quantum dots, as well as nanosensors, nanodiagnostics aims to provide more sensitive, accurate, and rapid diagnostic methods compared to traditional techniques. These innovations enable the detection of diseases at early stages, even before symptoms appear, and can provide valuable information on disease progression and the effectiveness of treatments
