“…In previous articles, we have reported the preparation and stabilization in water of gold nanoparticles in the presence of dendritic core-shell architectures based on hyperbranched poly(ethylenimine) (PEI) [21,22] or hyperbranched poly(amidoamine) chemically analogous to PAMAM dendrimers called HYPAM [23,24]. Here, we present the synthesis and characterization of platinum nanoparticles stabilized by HYPAM and demonstrate that these easily accessible composite materials are suitable for use as a reusable homogeneous hydrogenation catalyst.…”

“…Furthermore, we were able to show that the penetration of the hydrophilic dye rhodamine B and the hydrophobic dye Nile red (NR) into skin could be enhanced compared to solid lipid nanoparticles and normal cream formulations [20,25]. Besides these biomedical applications CMS nanocarriers have been successfully used for the stabilization of metal nanoparticles, in catalytic reactions involving stabilized metal nanoparticles, and for the fabrication of nanogold-nickel coatings by electrodeposition [26][27][28][29][30].…”

We have synthesized core-multishell (CMS) nanocarriers with different outer shells and the self-aggregation behavior and the transport capacity of these nanocarriers were studied with the hydrophobic guest molecules Nile red (NR) and methotrexate (MTX). The outer shell either consisted of methoxypoly(ethylene glycol) (mPEG) or polyglycerol (PG) dendrons of generation one or two. NR was solubilized by all CMS nanocarriers. The solubilization of MTX could only be achieved with mPEG-terminated CMS nanocarriers. Depending on the encapsulated guest, the CMS nanocarriers showed self-aggregation. The NR loaded CMS nanocarriers all formed bigger aggregates with a radius between 110 and 170 nm. In the case of the MTX loaded CMS nanocarriers, the MTX prevented the formation of CMS aggregates and therefore its efficient transport

“…The application of core shell systems with a core of gold nanoparticles and polymer shells around is a completely new concept for the deposition of nano composite films [1]. The advantage of such layers is the possibility to form composite material far away from thermodynamic equilibrium conditions.…”

New possibilities in the design of gold-containing electrochemical coating systems for electronic applications are given by the incorporation of gold-nanoparticles in metal-matrix-systems. The major problem for the application of nanoparticles is the strong agglomeration of the particles in the electrolyte solutions, preventing the incorporation of nanoscaled dispersants.A complete new concept for the deposition of nano dispersion layers, overcoming this agglomeration challenge, is the application of core shell systems. Using these systems, it becomes possible for the first time to incorporate metal nanoparticles into electrodeposited metal layers to form metal nanoparticle metal matrix systems (MNP-MMS). The advantage of such layers is to form nanocomposite materials far away from the thermodynamic equilibrium. Especially for the combination of gold nanoparticles with a nickel matrix, a way is shown for the manufacturing of temperature-stable nanocomposite structures, because at least in the temperature range of electronic applications no loss of the dispersive character by diffusion processes is expected. By incorporating the precious metal material into the nickel matrix as the main electrodeposit, and reducing the top gold layer thickness, a possible way of reducing the gold consumption and an economic use of gold resources is shown.
