Study Notes
Nanotechnology: The Science of the Small
- Manipulation of matter at the atomic and molecular scale, primarily less than 100 nanometers.
- Two primary approaches:
- Top-down approach: Starts with a larger material and removes portions to create nanoscale structures.
- Bottom-up approach: Builds nanoscale structures atom by atom or molecule by molecule.
Nanorobots: Tiny but Mighty
- Robots designed to perform tasks at the nanoscale.
- Often operate within the human body or in other intricate environments.
Applications of Nanorobots
-
Medicine:
- Disease detection: Nanorobots can detect biomarkers at the molecular level.
- Drug delivery: Nanorobots can transport drugs directly to specific cells, improving treatment efficacy.
- Cancer treatment: Nanorobots can target and destroy cancer cells.
- Tissue regeneration: Nanorobots may assist in regrowing damaged tissues.
-
Environmental cleanup:
- Microbial Remediation: Nanorobots can enhance microbial remediation of pollutants by increasing the efficiency of microorganisms.
