Development of gold nanorods for cancer treatment

Journal of Inorganic Biochemistry, 2021
There has been growing interest in the application of gold nanorods (GNRs) to tumor therapy due to the unique properties they possess. In the past, GNRs were not used in clinical treatments as they lacked stability in vivo and were characterized by potential toxicity.

Gold Nanorod Bioconjugates

Chemistry of Materials, 2005
Gold nanorods have been stabilized, conjugated to antibodies, and characterized for biological applications. The stabilizing surfactant bilayer which surrounds gold nanorods was replaced by thiol terminated methoxypoly(ethylene glycol) so that the nanorods are stable in buffer solutions free of surfactant. Nanorod bioconjugation was accomplished with a

Patterning of polyoxometalate rings on gold nanorods

Chemical Communications, 2020
Polyoxometalates (POMs) were self-assembled on cetyltriethylammonium bromide-covered gold nanorods and formed periodic POM rings, which could be used as templates for the synthesis of Ag nano-rings.

Spherical gold nanoparticles and gold nanorods for the determination of gentamicin

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2017
Gentamicin is an antibiotic indicated to treat mastitis in dairy cattle and for the treatment of bacterial resistance in the context of hospital infections. The effect caused by gentamicin on the optical properties of gold nanoparticles aqueous dispersions were used to develop quantitative methods to determine this antibiotic.

Watching Single Gold Nanorods Grow

Small, 2012
The consecutive evolution process of single gold nanorods is monitored using atomic force microscopy (AFM). The single-crystal gold nanorods investigated are grown directly on surfaces to which gold seed particles are covalently linked. The growth kinetics for single nanorods is derived from the 3D information recorded by AFM. A better understanding of

pH-Triggered Assembly of Gold Nanorods

Langmuir, 2005
The self-assembly of surfactant-protected gold nanorods (aspect ratio 3.3 +/- 0.3, 20.6 +/- 5.5 nm width, and 67.5 +/- 9.0 nm length) into ordered structures using adipic acid is presented. As made, the gold nanorods are coated with cationic surfactant, which gives them a net positive charge in aqueous solution. The pH-dependent assembly is directed by

Multiplex Biosensor Using Gold Nanorods

Analytical Chemistry, 2006
Gold nanorods (GNRs) with different aspect ratios were fabricated through seed-mediated growth and surface activation by alkanethiols for the attachment of antibodies to yield gold nanorod molecular probes (GNrMPs). Multiplex sensing was demonstrated by the distinct response of the plasmon spectra of the GNrMPs to binding events of three targets (goat ...

Stability of Crystal Facets in Gold Nanorods

Nano Letters, 2015
Metal nanocrystals can be grown in a variety of shapes through the modification of surface facet energies via surfactants. However, the surface facets are only a few atoms wide, making it extremely challenging to measure their geometries and energies.

Electrochemical Charging of Single Gold Nanorods

Journal of the American Chemical Society, 2009
Metal nanocrystals are commonly used to mediate important chemical reactions such as water splitting and CO oxidation. To investigate such redox reactions in detail, it would be useful to be able to carry out electrochemistry on single metal nanocrystals.

Study on selective oxidations of gold nanorod and mesoporous silica-coated gold nanorod

Journal of Materials Science, 2019
The structural control-based manipulation of the anisotropic surface plasmon resonance (SPR) property of gold nanorod (AuNR) is significant and has wide application value in many fields. In this work, the quantitative studies of the ends-selective oxidations of AuNR and silica-coated AuNR using chloroauric acid as a oxidant were carried out.
