Water scarcity is a world issue, and a solution to address it is the use of treated wastewater.
Indeed, in these wastewaters, pollutants such as pharmaceuticals, pesticides, herbicides …

We present metal-dielectric metasurfaces fabricated from metal periodical nanograting
deposited on a dielectric substrate. The metasurface consists of a modulated dielectric …

In this paper, we are relating a significant improvement of the SERS effect achieved with
assembled Au/ZnO nano-urchins. This improvement is realized thanks to an excellent …

Detection of illicit drug residues from wastewater provides a new route toward community-
level assessment of drug abuse that is critical to public health. However, traditional …

Herein, we investigate the chemical sensing by surface-enhanced Raman scattering
regarding two templates of gold nanocolumns (vertical and tilted) manufactured by glancing …

In this work, we present a study on the sensing of chemical molecules with Au nanoparticles
coated ZnO film by employing the photo-induced enhanced Raman scattering (PIERS) …

Surface enhanced Raman spectroscopy (SERS) is a powerful non-invasive technique to
detect and identify molecule traces. The accurate identification of molecules is based on the …

Many diverse technological applications, such as soft robotics and flexible electronics,
demand the development of intelligent sensors that can simultaneously detect different …

Nanoplasmonics is a research topic that takes advantage of the light coupling to electrons in
metals, and can break the diffraction limit for light confinement into subwavelength zones …

Generic, analytical equations are suggested for the localized plasmon excited in a narrow
gap formed between a metal/dielectric cylinder and a metal surface. The local distribution of …
