Background: Quantitative analysis of nanoparticle uptake at the cellular level is critical to nanomedicine procedures. In particular, it is required for a realistic evaluation of their effects. Unfortunately, quantitative measurements of nanoparticle uptak ...
The electrostatic driven complex formation between a weak polyampholyte chain and one pos. charged nanoparticle is investigated using Monte Carlo simulations. The influence of parameters such as the polyampholyte contour length, no. and size of blocks, nan ...
Two new water-soluble gold nanoparticles (AO-TEG-Au and AO-PEG-Au NPs) are prepared and characterized. They are stabilized by thioalkylated oligoethylene glycols and functionalized with fluorescent Acridine Orange (AO) derivatives. Despite the different co ...
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 ...
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 ...
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 ...
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 ...
The formation of complexes between nanoparticles and polyelectrolytes is a key process for the control of the reactivity of manufd. nanoparticles and rational design of core shell nanostructures. In this work, we investigate the influence of the nanopartic ...
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 ...
It is well known that the electrostatic repulsions between charges on neighboring sites decrease the effective charge at the surface of a charged nanoparticle (NP). However, the situation is more complex close to a dielec. discontinuity, since charged site ...
