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

Alkynylisocyanide Gold Mesogens as Precursors of Gold Nanoparticles
Inorganic Chemistry, 2011Gold nanoparticles (Au NPs) have been synthesized using simple thermolysis, whether from the mesophase or from toluene solutions, of mesogenic alkynyl-isocyanide gold complexes [Au(C≡C-C(6)H(4)-C(m)H(2m+1))(C≡N-C(6)H(4)-O-C(n)H(2n+1))]. The thermal decomposition from the mesophase is much slower than from solution and produces a more heterogeneous size

Antimicrobial Activity of Gold Nanoparticles and Ionic Gold
Journal of Environmental Science and Health, Part C, 2015Gold, in both nanoparticle (AuNPs) and ionic forms, has been studied for antibiotic activities. Some of the organic complexes of Au (I & III) ions are antibacterial. AuNPs are antifungal, but with conflicting results on their antibacterial activity. We summarized these publications and found that AuNPs are generally not bactericidal, or only weakly at ...
