Nanotechnology is being actively developed for many applications in the medical field, including drug delivery, biosensors and medical imaging. These nanomaterials are being advanced as novel and more targeted treatments for difficult to manage diseases such as cancers. Other materials are being developed as alternatives to conventional antibiotics in treating infections.
The use of engineered nanomaterial’s (nanoparticles) offer the ability to transport therapeutics to specific sites of a disease, thus reducing the off target toxicity of many drugs. This is especially true in the use of chemotherapeutics where off target reactions cause serious side effects in cancer patients. Additionally, the field of medical imaging can be improved with the ability for the specific targeting of diseased tissues at resolutions not capable with current technologies.
