A simple computational model demonstrates the assembly of self-limited filamentous bundles. The images are taken from dynamic Monte Carlo simulations in which chiral subunits spontaneously assemble under different interaction strengths and degrees of chirality.
fd virus is a polymeric virus 1 mm in length and 10 nm in diameter. We bind fluorescently labeled fd to 1 mm diameter polystyrene spheres creating a charged polymer stabilized colloid (hairy bead) and measure the interparticle potential using a double laser trap. We first measure the interaction energy of (a) bare beads and (b) then the hairy beads, seen here in fluorescence microscopy.
During the academic year, F08 - S09, Olin undergraduates Sean Calvo, Caitlin Greeley, Stephani Gulbrandsen, and Leif Jentoft designed, built, and tested a flexible automated microscopy platform capable of imaging an area up to 100mm x 100mm with a resolution of 10 microns at 4.8 second per square mm.
Stabilized emulsions containing the oscillating Belousov - Zhabotinsky chemical reaction (BZ) show interesting dynamics. Each drop acts as an independent chemical clock. However, they chemically communicate and exhibit collective behavior. In (a) three photos of the same hexagonally packed 100 micron diameter BZ drops are shown 80 seconds apart.
The ability to modify the electronic structure and properties of graphene is an important step towards the large scale fabrication of electronic devices based on graphene technology.
