Dissymmetrical Nanoparticles

2004
Half-way between molecular and materials chemistries lies the field of colloidal chemistry where the shape, the size, and the morphology of supramolecular assemblies are key parameters that determine their intrinsic properties, such as their interfacial behavior, surface chemistry, density, and so on.

Gelatin Nanoparticles

2019
Currently, gelatin nanoparticles are gaining more grounds in drug and gene delivery throughout all the available several routes of administration. Yet, the homogenous and less disperse preparation of this type of nanoparticles is still a challenging task due to the variation of the gelatin quality according to its source and due to its variable ...

Different Uptake of Metal Dioxide Nanoparticles (Ceria Nanoparticles, Zirconia Nanoparticles and Silica Nanoparticles) by Wheat

Bulletin of Environmental Contamination and Toxicology, 2019
Metal dioxide nanoparticles (NPs) are produced in ever-increasing amounts and widely used in industrial, medical and consumer products. They may pose potential risks to the environment. In this study we quantitatively evaluated the phytoavailability of CeO2NPs, ZrO2NPs and SiO2NPs to wheat (Triticum aestivum L.).

Novel nanoparticle matter: ZrN-nanoparticles

Applied Physics B, 2003
This work presents the results of the first preparation (to the best of current knowledge) and investigation of ZrN nanoparticles. The particles were produced by laser ablation/evaporation and adiabatic expansion from zirconium nitride powder targets. The particle size could be varied by applying different seeding gas flows. The size distributions were

Toxicity of Polyalkylcyanoacrylate Nanoparticles I: Free Nanoparticles

Journal of Pharmaceutical Sciences, 1982
The present report describes preliminary results concerning the acute toxicity of placebo polyalkylcyanoacrylate nanoparticles used as drug carrier. It was demonstrated that nanoparticles induced cellular damage only at relatively high concentrations in the cell culture medium.

Cell-targeted platinum nanoparticles and nanoparticle clusters

Organic & Biomolecular Chemistry, 2015
The facile preparation of cell-targeted platinum nanoparticles (PtNPs) is described, using designed peptides that as a single molecule control PtNP cluster growth, stabilise clusters in aqueous suspension and enable attachment of a versatile range of cell-targeting ligands.
