Dive into the nanoworld: manipulate matter at atomic scale (1-100 nanometers)! Use virtual scanning tunneling microscope (STM) and atomic force microscope (AFM) to see individual atoms, arrange them into structures. Create: (1) Carbon nanotubes (100x stronger than steel, conductive, lighter than aluminum - applications in electronics, composites), (2) Graphene (single-layer carbon, thinnest/strongest material, Nobel Prize 2010), (3) Quantum dots (nanocrystals glow different colors by size, use in displays, medical imaging), (4) DNA origami (fold DNA into nanostructures, drug delivery), (5) Nanoparticles (silver antimicrobial, gold cancer therapy).

Nanofabrication: top-down (lithography, etching) vs. bottom-up (self-assembly). Quantum effects: at nanoscale, quantum mechanics dominate - electron tunneling, surface plasmons, quantized energy. Applications: medicine (targeted drug delivery crosses blood-brain barrier), electronics (transistors now 5nm!), energy (nanostructured solar cells, batteries), materials (self-cleaning glass, stain-resistant fabrics), environment (water filtration, pollution sensors).

Pioneers: Richard Feynman 1959 "There's Plenty of Room at the Bottom" vision. Safety concerns: nanoparticle toxicity (can penetrate cells, lungs), environmental impact, regulation needed. Career: materials scientist, nanofabrication engineer, research scientist.
