Nanotechnology is revolutionizing modern medicine through its ability to manipulate materials at the molecular level. In diagnostics, nanoscale sensors and imaging agents enhance the detection of diseases at earlier stages with greater precision. **Nanoparticles** are used for targeted drug delivery, reducing side effects by delivering medication directly to diseased cells. **Nanotechnology** also aids in developing advanced therapies, such as gene editing and regenerative medicine, and in creating new materials for prosthetics and implants. By improving diagnostics, treatment efficacy, and personalized medicine, nanotechnology holds the potential to transform medical practices and patient outcomes.
