Phospholipid−Gold Nanorod Composites
ACS Nano, 2009Phospholipids comprise an enormous range of chemical structures that provide much of the functionality associated with cellular membranes. We have developed a simple method for incorporating phospholipids onto the surfaces of anisotropic gold nanorods as a stepping-stone for creating responsive and multifunctional nanocomposites.

Surfactant (Bi)Layers on Gold Nanorods
Langmuir, 2011Gold nanorods in aqueous solution are generally surrounded by surfactants or capping agents. This is crucial for anisotropic growth during synthesis and for their final stability in solution. When CTAB is used, a bilayer has been evidenced from analytical methods even though no direct morphological characterization of the precise thickness and ...

Biofunctionalization of gold nanorods
Pure and Applied Chemistry, 2010Gold nanorods (NRs) are promising nanomaterials for biotechnology innovations that include photoassisted drug delivery, gene therapy, noninvasive cancer detection, and ultrasensitive biodetection. Owing to their unique geometry, Au NRs exhibit surface plasmon (SP) modes in the near-infrared (IR) wavelength range—ideal for carrying out optical ...

Development of gold nanorods for cancer treatment
Journal of Inorganic Biochemistry, 2021There 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.

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, 2020Polyoxometalates (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, 2017Gentamicin 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.
