Study Notes
Introduction to Nanomaterials and Nanoscience
- Nanoscience is the study of the behavior of materials on a nanoscale (typically measured in nanometers, nm)
Key Aspects of Nanomaterials
- Unique properties compared to bulk materials due to their small size, such as increased surface area and reactivity
- Can have different physical, chemical, and biological properties compared to their bulk counterparts
Pioneer in Nanotechnology
- Richard Feynman, an American physicist, known for his 1959 lecture "There's Plenty of Room at the Bottom" which is considered a seminal work in the field of nanotechnology
Examples of Nanomaterials
- Carbon nanotubes (CNTs) with diameters in the nanometer range
- Quantum dots (tiny crystals of semiconductor material) used in biomedical imaging and optoelectronics
- Gold nanoparticles (GNPs) used in applications such as biomedical imaging and catalysis
- Liposomes (nanoscale vesicles) used in drug delivery and biomedical imaging
Approaches in Nanotechnology Synthesis
- Top-down approach: creating smaller structures from larger ones through techniques such as lithography and etching
- Bottom-up approach: building nanostructures atom by atom or molecule by molecule using techniques such as chemical vapor deposition (CVD)
