An electrochemical aptasensor for the sensitive detection of Pb2+ based on a chitosan/reduced graphene oxide/titanium dioxide

Proposing a Selective Electrochemical Sensor for Pb2+ Prepared from Fish‐Waste‐Derived Hydroxyapatite/Gelatin nanocomposite

“…[8] Moreover, modified electrodes offer the researcher the advantage of using a wide range of electrode materials, depending on their specificities and availabilities. [9][10][11] Graphite-modified electrodes have been extensively developed due to their low cost, high selectivity, sensitivity, specific surface area, electrical conductivity, mechanical flexibility and extreme resistance to oxidation. [12] Furthermore, these properties can be improved by adding modifiers in their composition.…”

Label free electrochemical sensors for Pb(II) detection based on hemicellulose extracted from Opuntia Ficus Indica cactus

“…Various biomolecules are designed to target metal ions. For example, we can cite whole cells [10,11], DNA-zymes and DNA aptamers [12][13][14], and recent reviews have been published in this field [15,16]. Aptamer-based sensors have been considered an innovative tool in metal monitoring due to their stable interaction, weak detection limit, and high selectivity [3,17].…”

Homogeneous voltammetric sensing strategy for lead ions based on aptamer gated methylthionine chloride@UiO-66-NH2 framework as smart target-stimulated responsive nanomaterial

“…inductively coupled plasma mass spectrometry, electrochemiluminescence, atomic absorption spectroscopy, colorimetry and fluorescence sensing, have been developed for Pb 2+ analysis. [11][12][13][14][15] These methods are generally reliable and accurate, but most of them do require professional technicians, time-consuming or complex operation programs. Alternatively, the electrochemical sensor, featuring fast response, high sensitivity, and good portability, has received tremendous attention.…”
