Impact on Medicine:
Drug discovery, which once took over a decade, is now accelerated by computational biology, AI drug screening, and lab-on-chip technologies. This shortens development cycles while reducing costs and risks.
4. Nanotechnology in Medicine
Nanomedicine applies nanotechnology (the manipulation of matter on the atomic scale) to healthcare.
Applications:
-
Targeted Drug Delivery: Nanoparticles carry drugs directly to diseased cells, reducing systemic side effects (e.g., in chemotherapy).
-
Imaging Enhancements: Nanoparticles improve the resolution of MRI and other imaging methods.
-
Biosensors: Nano-scale sensors detect biomarkers for diseases at very early stages.
-
Wound Healing: Nano-coatings in dressings promote faster healing and prevent infections.
The ability to work at the cellular and molecular level makes nanotechnology one of the most revolutionary tools in modern medicine.
