In the present work Y2Sn2O7:Eu nanoparticles dispersed in Y2O3 matrix (Y2Sn2O7:Eu–Y2O3) have been synthesized with a view to improve the luminescence properties of Eu in Y2Sn2O7 host. These nanoparticles are found to retain their nanocrystalline nature even at elevated temperature as high as 1300°C. Luminescence from the sample has been compared with bulk and nano-size dimensions particle of neat...
In this study surface coated poly-(ɛ-caprolactone) (PCL) nanoparticles with chitosan (CS) were developed as a carrier system for nasal immunization using recombinant Influenza A virus (A/California/07/2009) H1N1 hemagglutinin (HA) protein, for the induction of humoral, cellular and mucosal immunity. CS coated PCL (CS–PCL) nanoparticles were characterized in vitro for their percent yield, size, shape,...
