Featured Expert: Stacey Harper

Stacey Harper currently leads the Nanotoxicology Division of the Tanguay laboratory at Oregon State University, (OSU) and is an active member of the Oregon Nanoscience and Microtechnologies Institute (ONAMI). Dr. Harper works closely with industry, academic and government partners to ensure that environmental and human health considerations are addressed concurrently with the invention of novel nanomaterials by providing evaluations and feedback on the potential bioactivity and toxicological action of nanomaterials they produce. She has spearheaded an OSU/ONAMI effort to develop a knowledgebase of Nanomaterial-Biological Interactions (NBI) (www.oregonstate.edu/nbi).

6. Pulse-reversed electrodeposition with QCM monitoring to make magnetic nanowires in a nanotemplate
Cobalt nanowires with high perpendicular magnetic anisotropy are formed in a diblock copolymer film template using a pulse-reversed voltage with QCM monitoring. This in situ monitoring system along with the pulse-reversed field enables new control over the magnetic crystal growth.

3. Fabrication of a nanoporous template from a diblock copolymer film - neutral brush
A perpendicular orientation of cylindrical microdomains in diblock copolymer thin films is achieved by control over polymer-surface interactions. The block which forms cylindrical microdomains is removed by UV exposure and a chemical rinse to yield a nanoporous polymer film. The porous film can be used as a template for electrodeposition of metal nanodots or as a mask for reactive ion etching.

2. Fabrication of a nanoporous template from a diblock copolymer film - solvent annealing
An evaporation-induced flow in solvent cast block copolymer films can produce arrays of nanoscopic cylinders oriented normal to the surface and solvent annealing could markedly enhance the ordering of block copolymer microdomains in thin films. Without removing minor components, solvent-induced surface reconstruction can produce nanoporous structure in thin films. The porous film can be used as a template for deposition of quantum dots or as a mask for pattern transfer to the underneath substrates.
