Nanotechnology is significantly advancing drug development, with applications including dendrimers, liposome capsules, quantum dot imaging, self-assembling peptides, and hydrogels. While many nanotechnology-based drugs are in testing, doxorubicin is currently the only commercially available option. The field of nanomedicine encompasses various drug delivery and imaging methods, as well as potential uses in medical devices and biomedical research. Research is also exploring the use of DNA and RNA in conjunction with nanoengineered systems for innovative treatments, particularly with siRNA, which can inhibit protein formation. The integration of these technologies holds great promise for future medical applications.
