We report for the first time a distance-based paper device based on gold/silver core shell nanoparticles (Au@Ag NPs) for a simple, inexpensive, instrument-free, and portable determination of cyanide by the naked eye. Au@Ag NPs immobilized on a paper

Silver nanoparticles were synthesized by bioreduction of silver nitrate using the aqueous leaf extract of Combretum indicum (CI-AgNPs). The synthesized CI-AgNPs exhibited a distinct absorption peak at 414 nm in UV-vis spectroscopy. Various parameters

A paper-based method for heating preconcentration (PAD-HP) has been developed for the determination of Pb2+, Cd2+, Fe3+, and Ni2+. The design of our heating system was evaluated for dual quantification of ions using electrochemical and colorimetric m
