Nano Day 3

Self Assembly

Nano Object of the Day

Stained Glass Troy Dassler

NISEnet Stained glass lesson plan UW Madison

You are self assembled.

Examples and Explorations of self assembly

Gold Nanostructures (Venetian stained glass)

Gold and silver nanostructures change color with size.

Gold nanoparticles (coated glass) are used to heat via IR and kill cancer cells.
Silver nano particles are used to kill bacteria.
Precipitated particles return to the original color

Encapsulation, Micelles, and self assembly NNIN

Starch iodine solution version of encapsulation.

Models of self-assembly

Crystal self assembly, Sodium chloride by evaporation.

Floating Coins, aluminum coins float on water and assemble into crystal structures.

A short version of self-assembly by floating coins.

Garden of magnets, floating magnets form crystalline arrays.  Circular symmetry, square symmetry.

Garden of magnets mini   A smaller version of self assembled magnets.

Liquid Crystals
