Colloidal ß-TCP Facilitates Synthesis of Collagen Nano-composite

Shibata Y., Yamamoto H., Miyazaki T., Showa University, JP

Recently, hydroxyapatite/collagen composites have received much attention in the field of tissue reconstruction, because human bone is mainly composed of hydroxyapatite and collagen fibers. However, these composites cannot be synthesized without secondary treatments, therefore the [...]

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 [...]

Bioactive Ferrimagnetic Glass-Ceramics for Magnetic Induction Hyperthermia

Bretcanu O., Vernè E., University "Politecnico di Torino", IT

Ferrimagnetic glass-ceramics are potential candidates for magnetic induction hyperthermia, which is one form of inducing deep-regional hyperthermia, by using a magnetic field. The aim of this work is the preparation and characterization of innovative bioactive [...]

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 [...]

Multivalent Circular Aptamers: Versatile Nanostructures for Biomedical Applications

King G.C., Knox S.M., Williams B.B., Harris J., Gupta D.M., Di Giusto D.A., Gabutero E.R., Tyrelle G.D., Lai Y.-C., Aung M.T., McCutcheon S.T., Voelcker N., Le H.T.T., School of Biotechnology and Biomolecular Sciences, AU

Much recent interest has focussed on applications of DNA in nanotechnology, while chemical biologists have adapted evolutionary processes to generate aptamers, folded nucleic acids with molecular recognition properties similar to protein antibodies. As yet there [...]

pH-Sensitive Nano-Crystals of Carbonate Apatite Regulate Delivery and Release Kinetics of DNA for Efficient Expression in Mammalian Cells

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

The completion of whole human genome sequencing encourages the development of a powerful gene delivery technology for elucidating structure, regulation and function of genes and proteins in addition to the emerging biomedical applications, such as [...]
