have attracted a lot of interest to develop health and wellness promoting foods and beverages. However, bioactive lipids are water-insoluble and degrade easily during processing and storage, making their addition into foods and beverages challenging. The main objective of this thesis was to develop a novel green process to form bioactive lipid-carrier hollow solid lipid micro-and nanoparticles ...

metal—polyaniline nanocomposites such as platinum-polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of pt+4 ions into pt nanoparticles. thepolymerization of aniline was carried out in the presence of 1(2ptcn6 [potassium hexa cyanoplatinate (iv)] as oxidizing agent. during the reaction aniline monomers undergo oxidation andform polyaniline (pant) w...

This work investigates the effect of the sequential availability of ZnO nanoparticles, (nanorods of ∼40nm) loaded within a degradable poly(lactic acid) (PLLA) matrix, in cell differentiation. The system constitutes a dynamic surface, in which nanoparticles are exposed as the polymer matrix degrades. ZnO nanoparticles were loaded into PLLA and the system was measured at different time points to ...

Development of a green chemistry process for the synthesis of silver nanoparticles has become a focus of interest. This would offer numerous benefits, including ecofriendliness and compatibility for biomedical applications. Here we report the synthesis of silver nanoparticles from the reduction of silver nitrate and an aqueous extract of the lichen Parmotrema praesorediosum as a reductant as we...

magnetite (fe 3 o 4  and nio) nanoparticles with a size range of 40–60 nm were prepared by sol-gel technique in nano and micro reverse micelles (water- in-oil). the surface properties, size, morphology and crystallographic structure of fe 3 o 4 and nio particles are characterized by means of x-ray diffraction, transmission electron microscope and scanning electron microscope which will give muc...

INTRODUCTION The field of Novel Drug Delivery System is emerging at an exponential rate with the deep understanding gained in diversified fields of Biotechnology, Biomedical Engineering and Nanotechnology. Many of the recent formulation approaches utilize Nanotechnology that is the preparation of Nanosized structures containing the API. Nanotechnology, as defined by the National Nanotechnology ...

Recent progress in experiment on quantum tunnelling of the magnetic moment in mesoscopic systems will be reviewed. The emphasis will be made on measurements of individual nanoparticles. These nanomagnets allow one to test the border between classical and quantum behaviour. Using the micro-SQUID magnetometer, waiting time, switching "eld and telegraph noise measurements show unambiguously that t...
