The symmetry of magnetic quantum tunneling (MQT) has been studied in the prototype single molecule magnet (SMM) Mn12-acetate using a micro-Hall effect magnetometer and superconducting high field vector magnet system. An average crystal 4-fold symmetry is shown to be due to local molecular environments of 2-fold symmetry that are rotated by 90 degrees with respect to one another, confirming that...

PURPOSE Kidney Injury Molecule-1 is a protein that increases in urine following tubular damage. Kidney Injury Molecule-1 levels were correlated with the level of chronic kidney disease secondary to diabetic nephropathy in patients with type 2 Diabetes Mellitus. METHODS Clinical and laboratory findings of 142 patients with diabetic nephropathy and 34 control subjects were analysed. Creatinine ...

A micro-competition system is designed for simultaneous quantification of multiple glycans on intact cell surfaces, by integrating two-surface–one-molecule competition with surface enhanced Raman scattering (SERS). The micro-competition is achieved among multiple-polysaccharide-coated gold nanostars functionalized silica bubbles, target cells and gold nanoprobes at a micron scale. The gold nano...

This paper presents a study on the design and analysis of capacitively based Micro-Electro-Mechanical Systems (MEMS) sensor for continuous glucose monitoring (CGM) applications. This sensor consists of Parylene diaphragm, which is driven by a magnetic field and situated inside a micro chamber. A biocompatible sensing solution fills the micro chamber, which is separated from its surroundings by ...

A detection method that combines electric field-assisted virus capture on antibody-decorated surfaces with the "fingerprinting" capabilities of micro-Raman spectroscopy is demonstrated for the case of M13 virus in water. The proof-of-principle surface mapping of model bioparticles (protein coated polystyrene spheres) captured by an AC electric field between planar microelectrodes is presented w...

The design and development of many separation and catalytic process technologies require a proper quantitative description of diffusion of mixtures of guest molecules within porous crystalline materials. This tutorial review presents a unified, phenomenological description of diffusion inside meso- and micro-porous structures. In meso-porous materials, with pore sizes 2 nm < d(p) < 50 nm, there...

We used inline, micro-evaporators to concentrate and transport DNA targets to a nanoliter single molecule fluorescence detection chamber for subsequent molecular beacon probe hybridization and analysis. This use of solvent removal as a unique means of target transport in a microanalytical platform led to a greater than 5000-fold concentration enhancement and detection limits that pushed below t...

Reserpine a well known phytochemical molecule found in the dried roots of plants such as Rauwolfia Serpentina and Rauwolfia Vomitoria. It is a hypertension drug molecule used in drug formulation. Reserpine ranks as one of the most complex natural product of its size and contains 21 skeletal atoms compactly arranged in five rings. The stereo chemical complexity and biological significance of Res...

Recently micro particles or microspheres have gained great attention due to their free flowing powder characteristics and biodegradable nature generally made up of protiens or synthetic polymeric materials having particle size in the range of 1-200μm. Depending upon the encapsulation of active drug moieties there are two types of microspheres (microcapsules and micro matrices). Microcapsules ar...

an attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.
