: A more "biological" approach where scientists build materials atom-by-atom through chemical reactions and self-assembly. This method produces high-purity nanostructures like DNA origami, which can fold into "barrels" to carry drug payloads. 2. Targeted Drug Delivery: The "Magic Bullet"

: This involves taking larger materials and "carving" them down using mechanical energy, lithography, or etching to reach precise dimensions. Nanotechnology in Biology and Medicine: Methods...

: Modern MRI and CT scans now use gold and iron oxide nanoparticles as contrast agents, providing 10x sharper images that reveal tumors when they are only a few cells large. 4. Regenerative Medicine: Growing Back What’s Lost : A more "biological" approach where scientists build

We are entering an era where damaged organs can be repaired from within. Nanotechnology in Biology and Medicine: Methods...
