Gold Nanorod Substrate Request
A Biochemistry professor requested a quote for the following:
I am interested to have SiO₂ sputtered on glass coverslips. Diameter is 18 mm but other shapes or sizes would also work. SiO₂ thickness is 30–50 nm, single-side deposition. The coverslips will have gold or silica nanoparticles deposited on them (e.g., 25×45 nm gold nanorods or 60 nm silica spheres). Density of particles about 0.1/µm². Qty: 10–100 pieces.
Reference #215397 for specs and pricing.

What are Gold Nanorod Applications?
Gold nanorods are elongated nanoparticles with unique optical, electronic, and chemical properties, making them useful in various applications. Here are some key applications:
-
Biomedical Imaging
Surface Plasmon Resonance (SPR): Gold nanorods exhibit strong SPR, which can be tuned by adjusting their aspect ratio. This property is useful in imaging techniques like optical coherence tomography (OCT) and photoacoustic imaging, enhancing contrast in biological tissues.
-
Photothermal Therapy
Cancer Treatment: Gold nanorods can absorb near-infrared (NIR) light and convert it into heat, selectively destroying cancer cells without damaging surrounding healthy tissue. This makes them valuable in targeted photothermal therapy.
-
Drug Delivery
Targeted Delivery: Gold nanorods can be functionalized with ligands, enabling them to bind to specific cells or tissues. This targeted approach improves the efficacy of drug delivery systems, reducing side effects.
-
Biosensing
Detection of Biomolecules: Gold nanorods are used in biosensors to detect specific biomolecules, such as DNA, proteins, or glucose. Their surface can be modified to capture target molecules, and the resulting changes in optical properties can be measured for detection.
-
Surface-Enhanced Raman Scattering (SERS)
Molecular Detection: Gold nanorods can enhance the Raman scattering signals of molecules adsorbed on their surface, enabling highly sensitive detection of chemical and biological species.
-
Catalysis
Chemical Reactions: Gold nanorods can act as catalysts in various chemical reactions, including oxidation and reduction processes, due to their large surface area and active sites.
-
Optoelectronics
Solar Cells and Sensors: The unique optical properties of gold nanorods make them useful in enhancing the performance of optoelectronic devices, such as solar cells and light sensors.
-
Diagnostics
Colorimetric Assays: Gold nanorods change color when aggregated, a property that can be exploited in diagnostic assays for detecting the presence of specific analytes.
These applications leverage the tunable optical properties, biocompatibility, and surface chemistry of gold nanorods, making them highly versatile in both medical and technological fields.
