What term describes using nanoscale materials to diagnose, treat, and prevent diseases and to deliver medicines precisely?

• A. Nanomedicine
• B. Nanolithography
• C. Nanorobotics
• D. Nutraceuticals

Answer: (A)

Using materials at the nanoscale to diagnose, treat, prevent diseases, and deliver medicines precisely is nanomedicine. This field blends nanotechnology with medical practice to create tiny particles or devices that can identify disease markers, image it, and deliver therapies directly to affected cells. The precision delivery helps maximize therapeutic effects while reducing side effects, and it also opens possibilities for combining diagnosis and treatment in one platform (theranostics). For example, nanoparticles can be engineered to carry anticancer drugs straight to tumor cells and release the payload in response to specific signals, while also enabling better imaging to track treatment progress.

Nanolithography, by contrast, is about patterning at the nanoscale, nanorobotics envisions tiny autonomous machines, and nutraceuticals refer to nutritional supplements with health benefits.
