Cancer nanotechnology is a rapidly evolving field that aims to develop novel nanoscale materials and devices for the diagnosis, imaging, and treatment of cancer. Nanotechnology is the manipulation of materials and devices at the nanoscale level, which is approximately 1 to 100 nanometers in size. This small size allows nanoparticles and nanodevices to interact with biological systems in unique ways, including improved cellular uptake, increased blood circulation time, and enhanced targeting of cancer cells.
In cancer nanotechnology, nanoparticles can be designed to selectively target cancer cells, deliver drugs directly to the tumor site, and enhance the efficacy of chemotherapy and radiation therapy. Nanoparticles can also be used for imaging and diagnosis, allowing for earlier detection and more accurate characterization of tumors.
Recent research in cancer nanotechnology has focused on developing multifunctional nanoparticles that can perform multiple tasks simultaneously, such as targeting, imaging, and drug delivery. Additionally, researchers are exploring the use of nanoscale devices and systems for cancer therapy, including nanorobots that can selectively destroy cancer cells and nanoscale sensors that can detect and monitor cancer in real time.
