IBAD Nanothick Bioceramic Incorporation on Metallic Implants for Bone Healing Enhancement. From Physico/Chemical Characterization to In-vivo Performance Evaluation

Coelho P.G., Lemons J.E., University of Alabama at Birmingham, US

Preliminary data on in-vivo performance of nanothick bioceramic IBAD-coated metallic implants showed an increase in both osteoblastic activity and mechanical properties for bone surrounding these implants. The purpose of this study was to characterize a [...]

Hierarchical Natural Materials: Nanostructured Keratin

Martínez-Hernández A.L., Velasco-Santos C., de Icaza M., Martínez-Hernández A.L., Santiago-Valtierra A.L., Castaño V.M., CFATA-UNAM /ITQ, MX

Smart materials are required in devices in order to develop different functions referent to control and automation. The performance and applications of these materials have been growing in the last years and recently their development [...]

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 [...]

Regular Nano-Pores Fabricated By UV Cross-Linking Non-softbaked SU-8 Resist In a Solvent Evaporation Controlled Environment

Chang C-J, Tseng F-G, Yang C-S, National Tsing Hua University, TW

This paper proposes a novel technology to fabricate 3D nano pore structures in SU-8 resist, a widely employed resist in MEMS and Bio-chips. Controlling the evaporation rate in SU-8 fabrication process, regular porous structures with [...]

Development of Nano-sized Protein Arrays using Block Copolymer Self-Assemblies

Jung H-T, Jung J-M, Kwon K.Y., Ha T-H, Chung B.H., Jung H-T, Jung J-M, Korea Advanced Institute of Science and Technology, KR

The single molecule approach is potentially of great technological interest as a complementary means to obtain information about protein conformation or molecular interaction. The measurement for molecular interaction in single molecule level requires that the [...]

Nanotechnology Based on Spatially Fixed ds DNA (RNA) Molecules

Zakharov M.A., Yevdokimov Yu.M., Skuridin S.G., Nechipurenko Yu.D., Engelhardt Institute of Molecular Biology of RAS, RU

A new strategy of creating nucleic acid nanostructures is described. Our approach is based not on isotropic dsDNA (or RNA) molecules, but on these molecules fixed in spatial structure of their liquid-crystalline particles.The nanostructure formed [...]

Ca-Mg Phosphate Nano-Crystals for High Efficiency Gene Delivery and Expression in Mammalian Cells

Chowdhury E.H., Akaike T., Tokyo Institute of Technology, JP

Significant efforts are now being made for the development of non-viral gene-delivery techniques as alternatives to the viral vectors for basic research and clinical medicine. Despite existence of a wide variety of non-viral techniques particularly [...]

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 [...]
