End-to-end linked nanorod dimer nanogap antennas exhibit superior plasmonic enhancement compared to monomers due to the coupling of localized surface plasmon resonances (LSPR) of individual nanorods. However, controlling the assembly to stop at the dimer stage is challenging. Here, we report a pH-controlled synthesis of Au nanorod dimer nanogap antennas in an aqueous solution using 1,4-dithiothreitol (DTT) as a linker.

- NdO nanoparticle grafted graphene nanocomposite (NOGG) was created using sonochemical treatment, resulting in a material with a high specific surface area and unique pore structure.
- The NOGG/GP composite paste electrode demonstrated improved electrochemical properties and superior electrocatalytic activity for detecting Adrenaline (AD) and Tyrosine (TY) compared to other electrode types.
- The electrode showed high sensitivity with detection limits of 50 nM for AD and 40 nM for TY, making it effective for analyzing these compounds in biological and pharmaceutical samples.
Article Synopsis
- Titanium dioxide nanoparticles were synthesized using a sol-gel method with hexafluorotitanic acid and poly(ethylene glycol) as a capping agent.
- These nanoparticles were used to enhance a graphite paste electrode for the simultaneous detection of uric acid and guanine, with optimal electrochemical performance noted at specific calcination temperatures.
- The method demonstrated strong, well-separated oxidation peaks for both compounds and showed linear detection ranges, achieving low detection limits in spiked urine and serum samples.
