Scaffold guided tissue regeneration is an emerging field in tissue engineering. 3-D porous, biodegradable scaffolds are seeded with cells which attach to the scaffold, proliferate and in the case of stem cells also differentiate. The scaffold degenerates and is absorbed to leave healthy tissue. ...

The present invention provides a unique 3D pancreatic-like model for co-culture of isolated pancreatic islets with endothelial cells on a PLLA/PLGA biodegradable polymeric scaffold. Insulin-dependent diabetes mellitus (IDDM) is a chronic inflammatory disease in which there is autoimmune-mediated ...

Summary By measuring the changing capacitance of each molecule as it flows through a measuring device, its' exact motion path can be measured accurately with sub-micrometer spatial resolution and millisecond time-scales, rather than relying on existing methods of concluding the motion of single ...

Description of Technology Of the metallic ions with anti-bacterial properties, silver is perhaps the best known. Use of antibacterial fibers/yarns manufactured from silver-nylon composites are still limited and do not afford prolonged protection due to loss of the silver ions, requiring ...

Summary A method to produce amides in one step without any unwanted by-products, by coupling of alcohols with amines with the liberation of hydrogen gas, catalyzed by unique ruthenium complexes. Amides are widely used in the industry (e.g. nylon, Kevlar) and have widespread importance in ...

Description of Technology A biofilm is a complex aggregation of micro-organisms marked by the excretion of a protective and adhesive matrix. Biofilms are also often characterized by surface attachment, structural heterogeneity, genetic diversity, complex community interactions, and an extracellular ...

Summary Real-time monitoring and analysis of fluid drop formation and dripping can be achieved by electrostatically "sensing" the formation and detachment of a drop of liquid. Replacing technologies in which the drop is first "seen" and only then analyzed, this technology may be used in fields in ...

This novel invention presents a cost effective process for the fabrication of ceramics packed with metal. These cermets composites are based on Boron Carbides with infiltrated copper. The process addresses the design of B4C and Cu cermets with two interpenetrating and interconnected networks of B4C ...

Summary A novel inorganic compound, which shows clear pyroelectric and piezoelectric properties despite the lack of spatial periodicity inherent to ionic crystals. Pyroelectricity is a property of certain crystals consisting of polarization developed in a crystal by an inequality of temperature. ...
