In this work, Chloroquine diphosphate, and the cationic dye Safranin-O were selectively
removed from water using the agar-graphene oxide (A-GO) hydrogel, produced via simple …

Herein, structural design of nitrogen-doped metal hexacyanocobalate nanocomposite (N-
MHCC; M= Zn, Ni, Fe) have been synthesized via facile precipitation and green synthesis …

We review some new methods based on surface‐enhanced Raman scattering (SERS) for
the nondestructive/minimally invasive identification of organic colorants in objects whose …

Polypyrrole (PPy) prepared in the presence of organic dyes has been recently studied due
to its interesting morphology and electronic properties. This present work describes the …

The origin of fluorescence in carbon dots (C-dots) is still a puzzling phenomenon. The
emission is, in most of the cases, due to molecular fluorophores formed in situ during the …

This work explores the application of chemometric techniques to the analysis of lipidic paint
binders (ie, drying oils) by means of Raman and near-infrared spectroscopy. These binders …

The use of surface‐enhanced Raman scattering methods for the quantitative determination
of different molecular species is not trivial as many parameters seriously affect the outcome …

Madder lake is the most utilized anthraquinone dyestuff in artworks. Its main constituents
(alizarin and purpurin, together with other natural dyes) form an organometallic complex (the …

Mauve was the first synthetic organic dyestuff to be manufactured industrially. The main
components of the dye are mauveine A, B, B2, and C. These molecules show four nitrogen …

The optically clear single crystals of pure and safranin dye-doped (0.01 and 0.05 mol
percent) triglycine acetate were produced using the slow evaporation solution approach …
