Many biological systems employ allosteric regulatory mechanisms, which offer a powerful means of directly linking a specific binding event to a wide spectrum of molecular functionalities. There is considerable interest in generating synthetic allosteric regulators that can perform useful molecular functions for applications in diagnostics, imaging and targeted therapies, but generating such mol...

A unique, but unifying, feature of ionic liquids (ILs) is that they are nanostructured on the length scale of the ions; in many ILs well-defined polar and apolar domains exist and may percolate through the liquid. Near a surface the isotropic symmetry of the bulk structure is broken, resulting in different nanostructures which, until now, have only been studied indirectly. In this paper, in sit...

Nanotechnology and nanomaterials have a promised future in different aspects of modern life that involve medicine, environment, space, energy, electronics, security, and many others. While the applications of nanomaterials seem to be limitless, new challenges are also being posed. With regard to the type of one-dimensional nanostructure of Cadmium Selenide (CdSe), there are three possible morph...

Metal thin film functional properties depend strongly on its nanostructure, which can be manipulated by varying nucleation and growth conditions. Hence, in order to control the nanostructure of aluminum thin films fabricated by RF magnetron sputtering, we made use of in-situ monitoring of electrical and optical properties of the growing layer as well as plasma characterization by mass and optic...

For a nanoplasmonic approach of wearable biochip platform, understanding correlation between near-field enhancement on nanostructures and sensing capability is a crucial step to improve the sensitivity in biosensing. A novel and effective method is demonstrated to increase sensitivity with the enhanced electric fields and to reduce noise with targeted functionalization enabled by transferring s...

In the last decade, Prussian blue (PB) has attracted increased scientific interest in various research fields, such as fuel cells, gas separation and pollution treatment. Due to its advanced catalysis, biocompatibility, selectivity and stability, PB has been widely used in biosensor construction. However, the formation of regular PB nanostructures is challenging due to its fast crystallization ...

In this paper, a sensitive chronocoulometric deoxyribonucleic acid (DNA) biosensor based on a nanostructure gold electrode was fabricated for detection of the femtomolar level survivin gene which was correlated with osteosarcoma by using hexaamine-ruthenium III complexes, [Ru(NH(3))(6)](3+), as the electrochemical indicator. The effect of different frequencies on the real surface area of the na...

Physical properties are crucial to gelatin utilization and the physical properties are determined by structure. Therefore, it is important to investigate the nanostructure and physical properties of gelatin over the full range of concentrations which are widely applied in research and industry. Nanostructure of gelatin can be investigated by atomic force microscopy (AFM). However, it is hard to...

Artificial enzyme mimics have attracted considerable interest due to easy denaturation and leakage of enzymes during their storage and immobilization procedure. Herein we describe the design of a novel mimic peroxidase, a nanostructure of sheet-like FeS prepared by a simple micelle-assisted synthetic method. Such a nanostructure has a large specific surface area and high peroxidase-like activit...
