Emerging insights into the use of carbon-based nanomaterials for the electrochemical detection of heavy metal ions

Hybridized sulfated-carboxymethyl cellulose/MWNT nanocomposite as highly selective electrochemical probe for trace detection of arsenic in real environmental samples

“…15,16 As we all know, differential pulse voltammetry (DPV), cyclic voltammetry (CV), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy have been employed for the sensitive determination of trace metal ions in different environment samples. 17,18 However, the electrochemical activity of glassy carbon electrodes (GCE) has poor selectivity, sensitivity, and repeatability to real samples as a result of delayed charge transfer kinetics, interference of coexisting metal ions, and low catalytic activity. To enhance the electrochemical activity, the GCE needs to be functionalized through different active substances (metal nanoparticles or carbon nanomaterials, etc.)…”

A Short Review on Miniaturized Biosensors for the Detection of Nucleic Acid Biomarkers

“…The transducer is the element that transforms the biorecognition event into a quantifiable signal, while the probe serves as the biorecognition molecule and recognizes the target DNA when it is immobilized on the transducer surface. In nucleic acid biosensors, the hybridization event has been detected using a variety of detection technologies, including label-free ones such as piezoelectric and SPR transduction and others that frequently require labels, such as electrochemical approaches [ 69 , 70 , 71 ]. Recently, a number of reviews that explain all the critical facets of the transduction phase have appeared in the literature [ 72 , 73 , 74 , 75 ].…”

Deep eutectic solvents induced changes in the phase transition behavior of smart polymers: a sustainable future approach

“…Based on the developed strategic and synergistic pathways of sustainable chemistry, applications of DESs are diversified into sustainable chemistry as innovative eco-friendly solvents. [40][41][42][43][44][45] Owing to the eco-friendly properties and sustainable features of DESs, DESs have emerged as novel green solvents in sustainable chemistry. The properties of the DESs can be easily tuned based on the HBAs, HBDs, synthesis protocols, component natures, water contents, chemical compositions, molecular sizes of species, purities, molar ratio, and temperature.…”
