Agri-food safety incidents not only threaten the life and health of consumers but also
seriously hinder the development of the food supply chain. It is generally accepted that the …

The concern about increasing heavy metal ions such as Pb 2+, Hg 2+, and Cd 2+ in the
environment threatens society. Metal-organic frameworks (MOFs) are found highly efficient …

Surface-enhanced Raman scattering (SERS), a powerful spectroscopic technique owing to
its abundant vibrational fingerprints, has been widely employed for the assay of analytes. It …

In this work, we propose an original approach for rapid and easy conversion of a thin Ag-Nb-
NO film into surface enhanced Raman scattering (SERS) active substrate. The initial Ag-Nb …

ZnO nanoparticles (ZnO‐NP) were prepared by a facile precipitation technique using di‐
isopropyl amine as precipitating agent. The morpho‐structure and porosity of the as …

The present study reports on the selective and sensitive detection of metals using xanthan
gum-capped chromia nanoparticles (XG-CrNPs). The nanoparticles were synthesized by the …

Toxic metals and metalloids pollution is a major ecological and human health issue, yet
classical detection methods are limited. Here we review surface-enhanced Raman …

A SERS substrate with high sensitivity and reusability was proposed. The chip consists of
multiple ZnO microcavities loaded with silver particles. Based on structural characteristics …
