Incorporation of functional foods and nutraceuticals such as carotenoids which suffer from poor water solubility and low bioavailability into nano-sized delivery systems can improve their solubility, stability and oral bioavailability. The aim of this study was to prepare β-Carotene nanodispersion and investigate the effects of preparation parameters by means of response surface methodology usi...

Silver nanostructures as an effective antibacterial materials were synthesized via three various hydrothermal, sono-chemical and microwave methods using water as a green solvent. Then Chitosan-Ag polymer based nanocomposites were made by a fast chemical procedure. The influence of power, temperature and time on the morphology and particle size of the products was investigated. Scanning electron...

The purpose of the present study was to formulate and evaluate donepezil loaded bio-nanoparticles for effective treatment of Alzheimer’s disease. For the preparation of bio-nanoparticles biomaterial was isolated from fruits of Carica papaya by an economic method. The biomaterial recovered from the concentrate was subjected for various physicochemical properties like color, solubility, ...

Single particle cryo-electron microscopy (cryo-EM) and 3-D reconstruction have emerged in recent years as a powerful tool for solving high-resolution 3-D structures of viruses and macromolecular complexes. However, sample preparation for single-particle cryo-EM typically relies on a dedicated purification step before EM sample grid preparation, for example, using column chromatography or gradie...
