Ferromagnetic Microdisks: Novel Magnetic Particles for Biomedical Applications

Novosad V., Fradin F., Buchanan K.S., Guslienko K.Yu., Yefremenko V., Rosengart A.J., Guy S.G., Bader S.D., Argonne National Laboratories, US
Biomagnetic technologies rely on the ability of biological substances to form supra-molecular structures when they are mixed with magnetic nanoparticles. In this report we will demonstrate how thin film growth technique combined with traditional mask-transfer [...]

Guided Neurite Growth on Patterned Carbon Nanotubes

Zhang X., Prasad S., Niyogi S., Ozkan C.S., Ozkan M., Ozkan C.S., Ozkan M., University of California Riverside, US
Nanomaterials substrates are suitable for functioning as cell scaffolds. Promotion of axonal growth and support for long distance regeneration are the two requirements in the various experimental strategies for spinal cord repair. Organic systems’ performance [...]

Magnetic Nanoparticles for Self Controlled Hyperthermia Treatment of Tumors

Haik Y., Mohite V., Chen C-J., Center for Nanomagnetics and Biotechnology, US
Self controlled magnetic hyperthermia at tumor sites requires magnetic particles with Curie temperature similar to that of the desired tumor temperature. Elevated temperature at the tumor site was reported to decrease the tumor resistivety to [...]

Amelogenin Nanospheres Supra-Molecular Assembly and the Preferential Orientation of Apatite Crystals

Moradian-Oldak J., Du C., Falini G., University of Southern California, US
Amelogenin self-assembly into nanospheres has been recognized as a key factor in controlling the oriented and elongated growth of carbonated apatite crystals during tooth enamel formation. We investigated the process of amelogenin self-assembly into higher [...]

Toxicity of Nanomaterials to Living Cells

Jin Y., Wu M., Zhao X., University of North Dakota, US
We have investigated the toxicity of nanomaterials to living cells at the cellular and molecular levels. Recently, nanomaterials have being rapidly developed and shown great potential for use in various bioapplications due to their unique [...]

Calcium-Alginate Nanoparticles for Nonviral Gene Delivery

You J-O, Peng C-A, University of Southern California, US
Natural biopolymers are widely used in the filed of drug and gene delivery. In this study, alginate nanoparticles were prepared using water-in-oil microemulsion as a template followed by calcium crosslinking of guluronic acid units of [...]

Nanofabrication of Bioselective Materials using Diverse Nanolandscapes Displayed on Live Viruses

Petrenko V.A., Olsen E.V., Sykora J.C., Kouzmitcheva G.A., Sorokulova I.B., Brigati J.R., Chen I-H., Chin B.A., Vodyanoy V.J., Auburn University, US
Filamentous phage, such as fd used in this study, are thread-shaped bacterial viruses. Their outer coat is a tube formed by thousands equal copies of the major coat protein pVIII (Figure 1, left). We constructed [...]

Differential Effects of Surfactants on Enzyme Activity and Transport across a Semipermeable Cell

Leung S.W., Lai J.C.K., Idaho State University, US
Differential Effects of Surfactants on Enzyme Activity and Transport across a Semipermeable Cell Solomon Leung1 and James C.K. Lai2 1 Corresponding Author, College of Engineering, P.O. Box 8060, Idaho State University, Pocatello, ID 83209 Fax: [...]

Elastic Properties of Aspergillus nidulans Studied with Atomic Force Microscopy

Zhao L., Schaefer D.M., Xu H., Modi S., LaCourse W.R., Marten M.R., Towson University, US
An atomic force microscopy (AFM) was used as a nanoindentor to measure cell wall mechanical properties of the model fungus Aspergillus nidulans in both hyphal and spore forms. Hyphae and spores were immobilized on polylysine-coated [...]

Bio-Detection and Chemical Fingerprinting using the Inductively Coupled Plasma Mass Spectrometer (ICP-MS) Technology

Adeyinka A., Kuzmanovic D., Schaefer D.M., Lev S., Towson University, US
In this project, we explored the bioaccumulation of a large variety of inorganic trace elements in Bacillus subtilis using an inductively coupled plasma mass spectrometer and compared it to other related and unrelated species. Bacillus [...]
