The application of engineered nanoparticles (ENP) increased almost exponentially during the last decade. Next to carbon based ENP, metal based ENP are the next most commonly employed. Utilization of such particles for medical applications, remediation of t ...
This study describes methods developed for reliable quantification of size- and element-specific release of engineered nanoparticles (ENP) from consumer spray products. A modified glove box setup was designed to allow controlled spray experiments in a part ...
Topographic nanostructuring of surfaces is a promising concept, in particular to improve the bio-integration of titanium orthopedic implants. In this context, a new method for the nanostructuring of anodised titanium surfaces was developed. Ordered topogra ...
Gold nanoparticles coated with homogeneous (MUS) or "striped" (MUS-OT) ligand shells can be conjugated with double or single stranded DNA, and particles with either ligand configuration effectively carry DNA into melanoma tumor cells. When endocytosis is i ...
We describe a simple and effective method to obtain colloidal surface-functionalized Au nanoparticles. The method is primarily based on irradiation of a gold solution with high-flux X-rays from a synchrotron source in the presence of 11-mercaptoundecanoic ...
Nanomaterials have been widely used to assist laser desorption ionization of biomolecules for mass spectrometry analysis. Compared with classical matrix-assisted laser desorption ionization, strategies based on nanomaterial-assisted ionization generate a c ...
Capacitance measurements of a polarised liquid|liquid interface show that the capacitance of the interface increases in the presence of an adsorbed monolayer of citrate-coated gold nanoparticles. This unusual observation can be explained by an increase of ...
We here report improved synthesis and in vitro interactions of amphiphilic hydrogel nanoparticles with the macrophage cell line J774A.1. Nanoparticles comprising dispersed hydrophobic nanodomains of poly(propylene glycol) within a continuous phase of hydro ...
Poly(maleic anhydride-alt-1-octadecene), a cheap and com. available polymer, was used to water-solubilize colloidal nanocrystals with various compns., morphologies, and sizes. Highly pure nanoparticles with homogeneous distributions of sizes and surface ch ...
Si3N4 nanopores functionalized with 4–4’ bipyridyl, 3.2–6.5 nm in diameter and 30–50 nm in length, are shown to interact with single, negatively charged, coated gold nanoparticles from 2.4 to 8.9 nm diameter. It is possible to detect the interactions throu ...
