Electronic effects in CdSe/ZnS quantum dots conjugated to Interleukin 10 antibodies

Torchynska T.V., Casas Espinola J.L., Douda J., López de la Luz O.S., Instituto Politecnico Nacional, MX

Photoluminescence (PL) and Raman scattering spectra of none- and bio-conjugated CdSe/ZnS and CdSeTe/ZnS quantum dots (QDs) have been studied. QDs, characterized by emission at 605, 655 and 705nm, have been conjugated with anti Interleukin 10 [...]

Boron Nitride Nanotubes functionalized with glucosamine as a potential novel carrier system for radioisotope and drug delivery

Ferreira Soares D.C., Ferreira T.H., Ferreira Soares D.C., Ferreira T.H., Costa-Moreira L.M., Martins Barros de Sousa E., Centro de Desenvolvimento da Tecnologia Nuclear, BR

In the present work, Boron nitride nanotubes (BNNTs) were synthesized and submitted to a functionalization process (coating) with glucosamine. The nanostructures were physicochemical and morphologically characterized by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Raman [...]

Multifunctional Micropatterned Nanofiber Capable of Cell Patterning, Metabolite Detection, and Growth Factor Delivery

Koh W.G., Lee H.J., Lee H.W., Lee H.J., Lee H.W., Park S., Yonsei University, KR

This study describes the development of multifunctional nanofiber scaffolds consisting of multiple layers of nanofiber scaffolds and nanofiber-incorporated PEG hydrogels. We fabricated double-layered nanofiber scaffolds that were micropatterned with PEG hydrogels by combining two-step sequential [...]

Clusters of Iron Oxide Nanoparticles for Efficient Magnetic Resonance Imaging

Lai P.S., Lai S.M., Lai P.S., Lai S.M., National Chung Hsing University, TW

Recently, self-assembling clusters of metal nanoparticles have been extensively investigated in various fields. To prepare these clusters, various ionic surfactants, have been employed as stabilizers or emulsifiers to form water-dispersed spherical clusters. However, these ionic [...]

Study on the novel drug vehicle with multimodal imaging function

Wu P.J., Liu T.Y., Institute of Biomedical Engineering, National Yang-Ming University of Taiwan (ROC), TW

Recently, in order to combine diagnosis with therapy in a single box, drug delivery systems (DDSs) associating with imaging functions were developed to improve the efficacy of diseases detection, delivery of therapeutic agents, and the [...]

Unravelling adsorption and alignment of amyloid fibrils at interfaces by probe particle tracking

Isa L., Jung J-M, Mezzenga R., Jordens S, ETH Zürich, CH

We report the first direct, non-invasive experimental evidence of a 2D isotropic–nematic transition for highly anisotropic nanoparticles at liquid–liquid interfaces by using passive fluorescent particle tracking. In order to illustrate the potential of this approach [...]

Synthesis of Ultra Small Biocompatible Magnetic Nanocomposites by Seeded Emulsion Polymerization

Kloust H., Pöselt E., Kappen S., Schmidtke C., Kornowski A., Pauer W., Moritz H.-U., Weller H., University of Hamburg, DE

We present the production of PEGylated particles in the lower nanometer range by a new seeded emulsion polymerization technique under micro-emulsion conditions, avoiding any treatment with high shear forces or ultrasonication. Hereby, the hydrophobic shells [...]

Vertically Aligned Patterned Peptide Nano Wires for Cellular Studies

Taskin M.B., Technical University of Denmark, DK

Over the years, scientific studies have shown that one crucial point when designing biological platforms is the strict environmental conditions required for cell and tissue culturing, such as pH, temperature, medium content and other parameters [...]

Simultaneous Measurement of Nitric Oxide and Oxygen Dynamics during Myocardial Ischemia Reperfusion of Rat

Lee G.J., Kang S-W, Kim O.K., Kim S.K., Kim O.K., Kim S.K., Shin J.-H., Park H.K., Kyung Hee University, KR

Myocardial function is dependent on a constant supply of oxygen from coronary circulation. Therefore the accurate measurement of oxygen concentration in postischemic myocardium is crucial to the assessment of myocardial viability and function. Nitric oxide [...]

Design of a noninvasive blood glucose Sensor

Wang-Roveda J.M., Nguyen D., Nguyen H.V., Nguyen D., Nguyen H.V., MIAO LLC, US

25.8 million Americans (8.3% of the U.S. population) have Diabetes Mellitus with an annual increase rate of 1.3 million cases 1. There is 1.9 million new cases in 2010 1. Diabetes also results in kidney [...]
