The Shape in Water

Tinkering with a method they helped develop over the last few years, scientists have for the first time used it to measure at the nanometer scale the

Even Better than DNA Origami

DNA is the stuff of life, but it is also the stuff of nanotechnology. Because molecules of DNA with complementary chemical structures recognize and bind to one

Projects and Programs

Modeling and Simulation of Nanofabrication (Archived)

Completed
While self-assembly is still in its relative infancy with respect to practical use, with much additional research required to reach maturity, the more widely utilized top-down methods will continue to require advances and modifications to improve current nanomanufacturing techniques. This modeling
CDSAXS instrument

Metrology for Nanolithography

Ongoing
Small Angle Scattering techniques are employed to measure, with sub-nm precision, pattern shape, dimensions, and orientation for structures created in periodic arrays. Critical-Dimension Small Angle X-ray Scattering (CD-SAXS) utilizes the variable-angle transmission scattering from a small beam size
SEM measurement of PS-PMMA lamellae on a neutral substrate

Directed Self-Assembly of Block Copolymers (Archived)

Completed
Diblock copolymers are long molecular chain polymers with two (di) regions, or blocks, of dissimilar monomers. They are constructed by covalently linking two different polymer chains at their ends. The two regions can be chosen so that they repel each other. Normally mixtures of different polymers
