INTRODUCTION Nanoparticles are rapidly developing as drug carriers because of their size-dependent properties. Lipid nanoparticles (LNPs) are widely employed in drug delivery because of the biocompatibility of the lipid matrix. AREAS COVERED Many different types of LNPs have been engineered in the last 20 years, the most important being solid lipid nanoparticles (SLNs), nanostrucured lipid ca...

Experiments are described which show that vernix caseosa has a mechanical barrier effect if it is deposited in an unbroken layer. Specific antibacterial properties were not detected in vernix. It is suggested that vernix is best left on a newborn infant because of its mechanical obstruction to bacterial passage.

Improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. In this work, Titanium dioxide (TiO2 )/Low density Poly Ethylene (LDPE) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. The Oxygen permeability of the nanocomposite with 4% of TiO2 decreased for about 16% comp...

background: environmental problems of the plastic materials used in food packaging and the demand for food quality improvements lead to the development of packaging in natural materials. edible films such as calcium alginate extend the shelf life by acting as a selective barrier against moisture and oxygen. the main objective of this study was to explore a calcium alginate based edible film to ...

background and objective: edible, biodegradable films, by acting as barriers to control the transfer of moisture, oxygen, lipids, and flavours, can prevent quality deterioration and increase the shelf life of food products. on the other hand, regarding edible film capacity in transferring food additives, extending shelf-life of food products could be considered. so by adding antimicrobial-antio...
