Fluorescence probe based carboxymethyl cellulose/Tb(III) nanocomposites for detection of Mn2+ with simpleness, rapidness and high sensitivity

Glutathione-capped Syzygium cumini carbon dot-amalgamated agarose hydrogel film for naked-eye detection of heavy metal ions

“…For Fe 3+ ion, various fluorometric methods were based on GQDs, sulphur-doped carbon dots (C-dots) and carbon quantum dots (CQDs), cranberry CDs, citric acid and (NH 4 ) 2 HPO 4 CDs, and alginic acid (AA) and ethane diamine (EDA) CDs (Zhang et al 2019;Xu et al 2015;Wu et al 2018;Zulfajri et al 2019;Chandra et al 2016;Liu et al 2015). Various colorimetric methods based on 4-mercaptobenzoic acid (4-MBA) and melamine (MA)modified Ag NPs, L-tyrosine Ag NPs and β-cyclodextrin Ag NPs, NH 2 -MIL-125(Ti)/carbon paste electrode (CPE) photoirradiation cathodic stripping voltammetry (CSV) method, and carboxymethyl cellulose (CMC)/Tb(III) nanocomposite fluorometric method were compared with GSH CD-agarose hydrogel film for Mn 2+ ion (Annadhasan et al 2014;Xu et al 2014;Ye et al 2018;Hu et al 2014). Furthermore, GSH CD-hydrogel film as a detection probe was used for standard samples of 1 mM of Pb 2+ , Fe 3+ , and Mn 2+ and treated the same as described for the prepared solutions (Pb 2+ , Fe 3+ , and Mn 2+ , 1 mM), and as shown in Supporting Information of Table S2, the obtained data of standard samples were well matched with the prepared metal ion solutions.…”

A New Cellulose-Based Fluorescent Probe for Specific and Sensitive Detection of Cu2+ and Its Applications in the Analysis of Environmental Water

“…Carboxymethyl cellulose (CMC), as a kind of water-soluble natural polymer, is usually found in the form of sodium salts with the advantages of excellent biocompatibility, nontoxicity, good biodegradability and easy modification [ 20 ]. Due to the presence of many active oxygen-containing groups (carboxyl and hydroxyl), CMC is also an ideal carrier in the field of multifunctional modifications and constructing diverse fluorescent materials [ 21 , 22 , 23 , 24 ], For example, Fan prepared fluorescent hydrogels and aerogel hybrid materials by covalent coordination of lanthanide ions (Eu 3+ or Tb 3+ ) with carboxyl groups of CMC, which can be used to the detection of Fe 3+ [ 23 ]. Ye synthesized a fluorescent probe CMC/Tb(III) for detecting Mn 2+ in aqueous solution [ 24 ].…”

Thus, it can be seen that CMC-based fluorescent probes have great application prospects due to their high sensitivity and selectivity, good processability, and operability.…”

A Facile Strategy for the Preparation of Carboxymethylcellulose‐Derived Polymer Dots and Their Application to Detect Tetracyclines

“…To date, several fluorescent CMC-based sensors have been developed, mainly focusing on modification, mixing, combustion, or hydrothermal methods; however, several drawbacks still exist: complex synthetic routes, time-consuming and rigorous reaction conditions, or unfriendly organic solvents used during sample preparation. [31][32][33][34][35] Hence, it is highly necessary to design water-soluble autofluorescent CMC polymer sensors with facile preparation methods and mild reaction conditions.…”
