Solid State and Diffusion NMR Spectroscopy as Applied to Characterization of Complex Formulated Products and Biological Materials

Ulvenlund S., Topgaard D., Gustavsson S., Sparr E., CR Competence AB, SE

Solid and semisolid formulations in pharmaceutics, cosmetics and foods normally comprise complex structures on the molecular and colloidal length scales. Proper understanding of the functionality of a formulated product, as well as rational optimization of [...]

Diagnosis of Skin Health Conditions Using Gold Nanoparticles

Panigrahi S., Murugesan K., Biswas S.C., ITC LTD, IN

This study reports a novel non-invasive technique for the detection of skin health conditions using gold nanoparticles (GNP). The feasibility of the use of these GNP in the diagnosis of skin health conditions was non-invasively [...]

Triple protection delivery system for retinaldehyde: Preparation, skin penetration and controlled release at the hair follicles

Supmuang P., Wanichwecharungruang S., Chulalongkorn University, TH

Vitamin A and its derivatives including retinaldehyde possess serious instability problem. To continuously supply skin with un-degraded retinaldehyde, nanoparticles which could penetrate into skin via hair follicles and then slowly release this vitamin A derivative [...]

Bicelles: New Lipid Nanosystems for Biomedical Applications

Barbosa-Barros L., Rodriguez G., Rubio L., Cocera M., Alonso C., de la Maza A., Lopez O., Inst. Advan. Chemistry Catalonia-CSIC, ES

Bicellar nanosystems are a fascinating category of morphologically adaptable and versatile lipid assemblies consisting in bilayered disk-shaped nanoaggregates formed in water by long and short alkyl chain phospholipids. Characteristics of these bicellar systems, such as [...]

Traceability of Polyethylcyanoacrylate nanoparticles through the Startum Corneum

Diaz Torres R., National University of Mexico, MX

We followed nanoparticles through the stratum corneum using tape stripping and the nanoparticles quatification was done using photoluminescence. We found some interesting data at 3 hrs of application of nanoparticles because it seems like nanoparticles [...]

Bioartifical mucosa: delivery of biomaterials to the skin-percutaneous device interface in in vitro human organotypic skin cultures

Peramo A., Marcelo C.L., Goldstein S.A., Martin D.C., University of Michigan, US

The use of medical devices passing through the skin has continued to rise. In conjunction with an increased use of catheterization and a general tendency toward minimally invasive procedures in medicine, the need for rapid [...]

Interaction of carbon nanotube material with rat skin by 21 T MRI

Sharma R., Shetty K., Liang R., Chen C-J., Florida State University, US

Carbon nanotubes are emerging as potential tools in drug delivery nanocarriers to target specific cell types and carbon cages filled with metal molecules and may improve MRI microimaging. The present paper reviews the current state [...]

Nano-Tecture: Developing Smart Skins in Architecture

Ataman O., Trautmann J., University of Illinois at Urbana-Champaign, US

This paper surveys a brief history of architectural skin materials and presents an ongoing research project about the development of the materials and fabrication concepts for a fundamentally new class of architectural composite. This type [...]

Dicationic gemini surfactant gene delivery complexes contain cubic-lamellar mixed polymorphic phase

Foldvari M., Wettig S., Badea I., Verrall R., Bagonluri M., University of Saskatchewan, CA

The characterization of structural properties of novel dicationic (gemini) surfactant-based DNA complexes as micro/nano-scale self-assembling delivery systems for cutaneous gene therapy is described and discussed as related to measured transfection efficiencies. Previous small-angle x-ray scattering [...]

Compact Modling of High Frequency Phenomena for On-Chip Spiral Inductors

Talwalkar N., Yue P., Wong S., Stanford University, US

This paper presents a physics-based compact model for predicting high frequency performance of spiral inductors. The model accurately accounts for skin effect and proximity effect in the metal conductors as well as eddy current loss [...]
