Emerging biotechnologies — A/L Biology

A. Nanotechnology in Biology Definition: Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale, typically between 1 to 100 nanometers, for various applications. Explanation: Nanotechnology involves creating and using materials, devices, and systems at the nanometer scale (one billionth of a meter). In biology, this technology allows scientists to work at the cellular and molecular level, enabling precise interventions that were previously impossible. Nanoparticles can be engineered to deliver drugs directly to specific cells, detect diseases at early stages, or repair damaged tissues. The small size of nanomaterials gives them unique physical and chemical properties that differ from their bulk counterparts, making them ideal for biological applications. Think of it as: Think of nanotechnology like having microscopic construction workers that can enter your body and repair damaged cells or deliver medicine exactly where it's needed, similar to how specialized repair crews fix specific parts of a building.
