A novel thiazole-based Schiffbase chemosensor SB1 with N-and O-donor atoms was
synthesized and characterized by different techniques (UV–vis, 13 C NMR, 1 H NMR, and …

Quantum dots (QDs) or semiconductor nanocrystals have been receiving great interest in
the last few years. In this paper, L-cysteine-coated CdSe/CdS core-shell QDs (λem= 585 nm) …

The primary aim of this review is to survey the literature on the ion sensing ability of quantum
dots. Sensing of both cations and anions is important, since both play significant roles in …

Di-2-pyridyl ketone isonicotinoyl hydrazone (H PKIH) and a range of its analogues comprise
a series of monobasic acids that are capable of binding iron (Fe) as tridentate (N, N, O) …

Dispersive liquid–liquid microextraction (DLLME) is applied for the determination of copper
in cereals and vegetable food samples using flame atomic absorption spectrometry (FAAS) …

Studies have shown that modification of critical cysteine residues in proteins leads to the
regulation of protein function. These modifications include disulfide bond formation …

A simple and sensitive spectrophotometric method for determination of trace copper in water
samples is proposed. In the presence of pH 4.6 HAc–NaAc buffer solution and surfactant …

A very sensitive flow injection method with spectrophotometric detection has been
developed for the on-line determination of copper in natural waters. The method exhibits a …

A simple and sensitive colorimetric method for the determination of trace copper (II) ions in
aqueous solution has been developed using diphenylcarbazide (DPC) immobilized sol–gel …

Highlights•Pencil graphite electrode (PGE) was modified with porous d-penicillamine (DPA)
functionalized nanocellulose (NC) for the first time.•Characterization of DPA/NC was done …
