As the title indicates, the book ‘Nanoparticles’ by R. Jelinek deals with objects at the nanometric scale. As nanoscience and nanotechnology devoted to nanoparticles represent an ‘enormous scope’, carboneous nanomaterials and preparation processes like lithography are excluded from the content. The aim of this book is to give an overview of nanoparticles to a reader who is not necessarily activ...

in this article, zno and zno:mn nanoparticles prepared by reverse micelle method. the various crystalline properties of these nanoparticles such as size, d-spacing, strain, stress, dislocation density and texture coefficient have been calculated with the help of xrd spectrum. the xrd results indicated that the synthesized zno and zno:mn nanoparticles have a pure wurtzite (hexagonal phase) struc...

tio2 thin films and ag/tio2 nanoparticles were prepared by cvd and plasma bombardment method. xrd results showed the presence of ag nanoparticles in tio2 matrix. sem image confirmed formation of ag nanoparticles. xps analysis was utilized to study the chemical state of the ag/tio2 nanostructure. statistical surface analysis revealed that since there is a linear relation between logarithmic diag...

abstractin the last step of desolvation method for preparation of albumin nanoparticles, glutaraldehyde (ga) is added to stabilize the newly formed nanoparticles. due to undesirable effects of ga, the objective of this study was to evaluate alternative methods of crosslinking including ultraviolet (uv) irradiation, adding of glucose and combination of both methods. the nanoparticles were prepar...

In order to develop a systemically administered safe and effective nonviral gene delivery system, cellular interactions and plasmid DNA transfection with poly(ethylene glycol)-modified (PEGylated) gelatin nanoparticles were examined. The DNA-containing nanoparticles were prepared by a controlled water-ethanol solvent displacement method. The nanoparticles were characterized for particle size, s...

The surface of lanthanide(III)-doped LaPO4 nanoparticles was modified by reaction with an alcohol, leading to a covalent bond between the ligand and the particle surface. The surface of lanthanide(III)-doped LaF3 nanoparticles was modified to alter the solubility of the nanoparticles and study the influence of surface effects on the luminescence of lanthanide ions doped in the nanoparticles. Th...

Recently, increasing attention has been paid to lecithin/chitosan nanoparticles as colloidal drug delivery system showing the great potential to improve the permeation of encapsulated drug across various biological barriers [1, 2]. However, the overall poor stability of colloidal nanoparticles in an aqueous medium is a significant drawback in their development perspective. Therefore, the aim of...

Poly(butylcyanoacrylate) nanoparticles were prepared by dispersion polymerization (DP) and emulsion polymerization (EP) of n-butyl cyanoacrylate monomer. The particles were characterized by infrared spectroscopy, differential scanning calorimetry, X-ray diffractometry and transmission electron microscopy. Particle properties such as size and zeta potential were determined for nanoparticles prep...

Nanoparticles have attracted increasing attention for local drug delivery to the inner ear recently. Bovine serum albumin (BSA) nanoparticles were prepared by desolvation method followed by glutaraldehyde fixation or heat denaturation. The nanoparticles were spherical in shape with an average diameter of 492 nm. The heat-denatured nanoparticles had good cytocompatibility. The nanoparticles coul...
