Magnetism in gold nanoparticles
Nanoscale, 2012Gold nanoparticles currently elicit an intense and very broad research activity because of their peculiar properties. Be it in catalysis, optics, electronics, sensing or theranostics, new applications are found daily for these materials. Approximately a decade ago a report was published with magnetometry data showing that gold nanoparticles, most ...

Gold nanoparticle superlattices
Chemical Society Reviews, 2008Ordered metal nanoparticle assemblies--superlattices--have captivated and stirred the imagination of scientists and engineers alike and promise great prospect for future technologies. This potential though will greatly be determined by the understanding and control that can be exerted on the assembling processes.

ChemPhysChem, 2009
AbstractNanoparticle chirality has attracted much attention recently, and the application of chiral nanoparticles to chiral technologies (see figure) is also of interest. This Minireview deals with advances in the preparation and characterization of chiral gold nanoparticles.

Thermosensitive Gold Nanoparticles
Journal of the American Chemical Society, 2004Thermosensitive gold nanoparticles were fabricated by conjugating Au with a thiol-terminated poly(N-isopropylacrylamide) or PPA; this polymer stabilizer exhibits a temperature transition while undergoing a hydrophilic to hydrophobic transformation. The introduction of PPA onto gold nanoparticles has sensitized Au nanoparticles with unique temperature ...

Radiosensitization by gold nanoparticles
Clinical and Translational Oncology, 2013Recent years brought increasing use of gold nano particles (GNP) as a model platform for interaction of irradiation and GNPs aiming radiosensitization. Endocytosis seems to be one of the major pathways for cellular uptake of GNPs. Internalization mechanism of GNPs is likely receptor-mediated endocytosis, influenced by GNP size, shape, its coating and ...

Gold nanospirals on colloidal gold nanoparticles
Journal of Colloid and Interface Science, 2019Synthesis of asymmetric nanostructures has always been a great challenge. In particular, there are only limited approaches for growing spiral nanowires in solution, and almost all of them require templates. Here, as a step in advancing the synthetic capability at the nanoscale, we report a wet chemistry template-free approach for growing hybrids spiral

Docking of Ubiquitin to Gold Nanoparticles
ACS Nano, 2012Protein-nanoparticle associations have important applications in nanoscience and nanotechnology such as targeted drug delivery and theranostics. However, the mechanisms by which proteins recognize nanoparticles and the determinants of specificity are still poorly understood at the microscopic level.

Phagocytosis of Biocompatible Gold Nanoparticles
Langmuir, 2010We report the evidence for the cellular uptake of gold nanoparticles via the phagocytosis mechanism in murine macrophage cells strongly supported by TEM and optical microscopy. Nanoparticles were prepared using several biocompatible molecules of choice (5-aminovaleric acid, l-DOPA, melatonin, and serotonin hydrochloride) as stabilizers for gold ...

Cytotoxicity of Gold Nanoparticles
2012Nanomaterials are now routinely used in technical as well as medical applications. The very physicochemical properties that favor nanomaterial application are the prime cause that these materials cannot be considered "generally safe." We are still far from predicting the toxicological profile of new nanoparticles, despite continuous attempts to ...

Chemistry – A European Journal, 2007
AbstractGold nanoparticles (≤1 nm) have been encapsulated inside cucurbit[7]uril (CB[7]) by vapor deposition or chemical reduction in aqueous solutions. CB[7] has unique host properties compared with CB[5] and CB[6]. The particle size distribution obtained with CB[5] and CB[6] is similar to that obtained in the absence of CBs and the particles obtained
