The discovery and utility of new methods based on different materials and chemical derivatisations for protein profiling of complex analytes is an ongoing field. This study includes the development, optimisation, validation and the application of a method based on the combined characteristics of physisorption and chemisorption of nano crystalline diamond (NCD) surfaces for serum profiling. Due to the expanded nano-structure Read More

Microwave plasma chemical vapor deposition (CVD) was used to grow nanostructured diamond onto mechanically polished superelastic Nitinol (NiTi) alloy. As determined by glancing-angle x-ray diffraction, mechanical polishing of the heavily oxidized as-received samples resulted in removal of nickel, Ni3Ti, and TiO2 surface phases, leaving the NiTi austenite (B2 type, CsCl structure) to be detected. Diamond nucleation and gr Read More

Hafnia and zirconia films have been synthesized via solution deposition on sulfonate-terminated molecular self-assembled monolayers (SAMs) that are covalently anchored on surfaces of silicon wafers. As-prepared inorganic films, consisting of packed nanoparticles, were formed by heat-induced hydrolysis and condensation in acidic aqueous solutions of hafnium inorganic salt. The effects of several key synthesis process p Read More

During biological nitrogen fixation, the nitrogenase Fe-protein containing the [4Fe-4S] metal cluster has been shown to function in electron transfer to the MoFe-protein. This function of the Fe-protein is dependent on its conformational state and the metal cluster of the active site. This review will summarize the structures of the nucleotide bound (or "off") and amino-acid-substituted Fe-protein as well as the properties of the metal Read More

Nanomagnets are expected to expand the capabilities of widely established technologies such as data recording and to implement new functionalities of applicability in biosciences. The basis for these potential benefits of nanomagnets is their intrinsic small size and their outstanding properties derived from finite-size and surface effects as well as collective phenomena and unusual transport properties. This review ai Read More

The delivery of drugs via skin routes has been extensively investigated. Nevertheless, clinical applications are limited by the stratum corneum (SC), the predominant barrier of the skin. One of the possibilities for increasing skin absorption or permeation of drugs is the use of nano/submicron vesicular systems. Classic liposomes are of little value as carriers for drug delivery via the skin because they do not deeply penetrate it. Read More

Due to the remarkable specific physical and chemical properties as well as the potential application, onedimensional (1D) nanomaterials, such as nanowires, nanofibers, nanobelts, nanorods, etc., have attracted great research interests. This paper explores the fabrication strategies that enable rational design and predictable production of 1D nanomaterials, such as crystallization and electrospinning, discusses several me Read More
