Addressing burdens of electronic waste (E-waste) leachate while achieving sustainable and selective recovery of noble metals, such as gold, is highly demanded due to its limited supply and escalating prices. Here we demonstrate an environmentally-benign and practical approach for gold recovery from E...
Scientists from Rice’s Laboratory for Nanophotonics (LANP) found a new method that solar-panel designers could use to incorporate light-capturing nanomaterials into future designs. Light-capturing nanomaterials such as metallic nanoparticles convert light into plasmons, or waves of electrons that flow l...
Using a Hg(II) sensor based on the aggregation of gold nanoparticles as a model system, we evaluated the performance of two portable low-cost devices that monitor the wavelength-ratiometric resonance Rayleigh scattering signal of the chemical sensor upon white-LED illumination. The first device uses...
One Step Synthesis of Single Walled Carbon Nanotubes/Gold Nanoparticles (SWCNTs/AuNps) Nanocomposite for Enhancing Electrochemical Response of Neurotransmitters Gold nanoparticles size and nanocomposite morphology have been studied by Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) observat...
We report on the straightforward preparation of gold nanoparticles (AuNPs) through a direct metal-to-substrate electric discharge at ambient conditions at 1.2 kV between the source metal (gold) and low-cost graphite screen-printed electrodes (SPEs). Considering that sparked nanoparticles are genera...

Green synthesis of nanoparticles using plants and microorganisms is biologically safe, cost effective, and environmentally friendly technology. Gold nanop...
First, a silicon nanowire array (SiNWA) is tailored by metal-assisted chemical etching (MaCE) method as a scaffold of the desired SERS substrate. Next, with an oblique angle deposition (OAD) method, optimized gold nanoparticles (AuNPs) are successfully decorated on the surface of the SiNWA. ...
Metal nanoparticles have found wide applications in medicine, information storage, optical devices, electronic, magnetic, photonics and catalytic reduction of environmental pollutants [13–15]. Owing to unique properties and applications, gold nanoparticles have become important in nanotechnology, and ...
