Recent Patents on Nanotechnology - Volume 5, Issue 3, 2011

In recent years, polymeric scaffolds have been used in several biomedical applications for delivery of drugs or other biologically relevant molecules. Polymeric nanostructures display different (and in some cases more powerful) properties respect to bulk materials. This, lead academic researchers and industry to cooperate in developing pioneering nanostructured materials for industrial and biomedical applications. Mor Read More

This review focuses on recent patents for the design and implementation of nanodevices to isolate and characterize single immune cells. Specifically, the most common categories of single cell assays were reviewed and new strategies were suggested to expand the capabilities of nanodevices further for the study of human immune disease.

Recent years have witnessed tremendous research in quantum dots as excellent models of quantum physics at the nanoscale and as excellent candidates for various applications based on their optoelectronic properties. This review intends to present theoretical and experimental investigations of the near-field optical properties of these structures, and their multimodal applications such as biosensors, biological lab Read More

Lithium transitionmetal (Fe, Mn, Co, Ni) silicate cathode materials are new promising substituting cathode materials for lithium ion batteries. They had caught the researchers' eyes in the past several years. Nowadays, there are growing interests for silicate cathode materials in the field of lithium ion batteries. Among the silicate cathode materials, Li2FeSiO4 is the most promising cathode materials because of its high struct Read More

The present invention provides Al-Si/SiC nanoparticles composites with the composition of 7%Si, 15%SiC with average particle size (APS) of SiC, 20, 30, 40 nm and 65μm using a novel double stir casting method. The inventive nano-composites by double stir casting show a nearly uniform distribution and good dispersion of the nano-particles within the Al matrix, although small agglomeration was found in the matrix of the Read More

The efficacy of current anti-cancer multimodal therapeutic strategies in gliomas is limited by the lack of specific therapies against malignant cells and the prognosis in patients affected by cerebral gliomas remains very unfavorable. Glial tumors seem to be able to create a favorable environment for the invasion of neoplastic cells when they combine with the extracellular matrix through the up-regulation of crucial pat Read More
