Biosynthesis of Gold Nanoparticles
Journal of Nanoscience and Nanotechnology, 2011Synthesis of nanoparticles with interesting physico-chemical properties using efficient as well as eco-friendly technology is one of the main objectives of nanotechnology. Biological systems have been reported to synthesize inorganic materials under certain circumstances.

Alkanetelluroxide-Protected Gold Nanoparticles
Langmuir, 2008The synthesis and characterization of the first air-stable tellurium-containing ligand-protected gold nanoparticles (NPs) are reported. Although the synthesis largely followed the well-known Brust two-phase approach, the starting ligand was dioctyl ditelluride rather than alkanetellurol, which is an analogue of the widely used alkanethiol.

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 ...

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 ...

Gold nanoparticles in delivery applications☆
Advanced Drug Delivery Reviews, 2008Gold nanoparticles (AuNPs) provide non-toxic carriers for drug and gene delivery applications. With these systems, the gold core imparts stability to the assembly, while the monolayer allows tuning of surface properties such as charge and hydrophobicity.

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 ...

Gold‐Nanoparticle‐Decorated Glass Microspheres
Particle & Particle Systems Characterization, 2013Patterning of microspheres with well-dispersed metallic nanoparticles (NPs) is a challenging task owing to NPs' high agglomeration potential. Here, a simple, three-step method is presented to decorate glass beads with gold nanoparticles arranged in a quasi-hexagonal manner.

Gold Nanoparticles Enhancing Protontherapy Efficiency
Recent Patents on Nanotechnology, 2015The insertion of gold nanoparticles in biological liquids, tissues and organs permits to increase the equivalent atomic number of the medium that, if used as target to be irradiated by ionizing radiation, permits an increment of the absorbed dose. No toxic nanoparticles, such as the Au, can be injected in the cancer tissues at different concentrations ...

Biocompatible gold nanoparticles
Materials Science and Technology, 2004AbstractThiolalkylated polyethylene glycol (PEG) ligands have been designed and synthesised for use in the manufacturing of stable water soluble gold MPCs. In addition to ongoing work on the synthesis of size and shape selective aq. (aqueous) gold nanoparticles, the effect of avidin gold nanoparticle (AGNP) ratio on biotinylated peptide gold ...
