Journal ArticleDOI

Nanoparticles--an efficient carrier for drug delivery into the hair follicles.

TL;DR: It was found that the nanoparticles penetrate much deeper into the hair follicles than the dye in the non-particle form, if a massage had been applied and without massage, similar results were obtained for both formulations.
Journal ArticleDOI

The human epidermis models EpiSkin, SkinEthic and EpiDerm: an evaluation of morphology and their suitability for testing phototoxicity, irritancy, corrosivity, and substance transport.

TL;DR: First results indicate their suitability for transport experiments of drugs and other xenobiotics across skin, but the barrier function of these reconstructed human epidermis models appears to be much less developed compared to native skin.
Journal ArticleDOI

Nanoparticles and their interactions with the dermal barrier

TL;DR: The interaction of nanoparticles with skin and especially skin models is an intriguing field, however, the data obtained do not show a clear image on the effect of nano-carriers and the penetration of such particles is an open and controversially discussed topic.
Journal ArticleDOI

Chitosan-coated PLGA nanoparticles for DNA/RNA delivery: effect of the formulation parameters on complexation and transfection of antisense oligonucleotides

TL;DR: The study proved the efficacy of chitosan-coated PLGA nanoparticles as a flexible and efficient delivery system for antisense oligonucleotides to lung cancer cells.
Journal ArticleDOI

Nanoparticles made from novel starch derivatives for transdermal drug delivery

TL;DR: Encapsulation and release properties of these nanoparticles were studied, showing high encapsulation efficiency for three tested drugs and a close to linear release profile was observed for hydrophobic drugs with a null initial burst effect.
