“…Curcumin contains a 1,3-diketone group including a stable ketoenol tautomeric state that allows it to form a strong complexation through a chelating mechanism with Pb 2+ ions. Positive results were observed for the presence of Pb 2+ using AgNPs-CUR, marked by a colour change from yellow to orange at a pH of 6, followed by floccular precipitates within 20 min [90]. Curcumin cellulose-nanofibers also changed colour from yellow to orange red at a pH of 5 [30,91].…”

“…For the detection of lead ions, three sensors were developed with different results: curcumin silver-nanoparticles (AgNPs-CUR) for solution-based sensors, and cellulose nanofibers and starch cryogel for fabricated sensors (Table 2). The curcumins used in the studies were extracted from fresh turmeric (Curcuma longa L.) [90] and powdered turmeric [30,91,92]. Curcumin contains a 1,3-diketone group including a stable ketoenol tautomeric state that allows it to form a strong complexation through a chelating mechanism with Pb 2+ ions.…”

An Update on the Use of Natural Pigments and Pigment Nanoparticle Adducts for Metal Detection Based on Colour Response

Natural pigments occur in plants as secondary metabolites and have been used as safe colourants in food. Studies have reported that their unstable colour intensity might be related to metal ion interaction, which leads to the formation of metal–pigment complexes. This underlines the need for further investigations on the use of natural pigments in metal detection using colorimetric methods, since metals are important elements and can be hazardous when present in large amounts. This review aimed to discuss the use of natural pigments (mainly betalains, anthocyanins, curcuminoids, carotenoids, and chlorophyll) as reagents for portable metal detection based on their limits of detection, to determine which pigment is best for certain metals. Colorimetric-related articles over the last decade were gathered, including those involving methodological modifications, sensor developments, and a general overview. When considering sensitivity and portability, the results revealed that betalains are best applied for copper, using a smartphone-assisted sensor; curcuminoids are best applied for lead, using a curcumin nanofiber; and anthocyanin is best applied for mercury, using anthocyanin hydrogel. This provides a new perspective on the use of colour instability for the detection of metals with modern sensor developments. In addition, a coloured sheet representing metal concentrations may be useful as a standard to support on-site detection with trials on masking agents to improve selectivity.

“…To date, several medicinally important phyto-polyphenols including curcumin, quercetin, and chitosan have been employed as metal-reducing, stabilizing, and surface functionalization agents. 11,13,20 Among several fascinating properties, magnetism in iron oxide NPs is the one which makes them a unique candidate within metallic NPs in different biomedical, clinical, and environmental settings. 4,21,22 The ionic state of iron is trivalent (Fe 3+ ) in four oxides, α-Fe 2 O 3 (hematite), γ-Fe 2 O 3 (maghemite), β-Fe 2 O 3 , and ε-Fe 2 O 3 ; Fe 3 O 4 (magnetite) and FeO (wustite) polymorphs possess tetravalent (Fe 4+ ) and bivalent (Fe 2+ ) ions, respectively.…”

A simple, facile, moist-heating ( e.g. , autoclave), one-step procedure for EGCG-mediated biosynthesis of narrow-size magnetic iron oxide (α-Fe 2 O 3 ) nanoparticles (EGCG-MINPs) was developed. The influence of pH of the reaction mixture over the size distribution of as-synthesized EGCG-MINPs was investigated systematically by employing UV–visible (UV–vis) spectroscopy and dynamic light scattering (DLS)-based hydrodynamic size, surface charge (zeta-potential), and polydispersity index (PDI). The FE-SEM, TEM, and XRD characterizations revealed that the EGCG-MINPs synthesized at pH 5.0 were in the size range of 6.20–16.7 nm and possess well-crystalline hexagonal shaped nanostructures of hematite (α-Fe 2 O 3 ) crystal phase. The role of EGCG in Fe 3+ ion reduction and EGCG-MINP formation was confirmed by FTIR analysis. The VSM analysis has revealed that EGCG-MINPs were highly magnetic nanostructures with the hysteretic feature of saturation magnetization (Ms), remanent magnetization (Mr), and coercivity (Hc) as 33.64 emu/g, 12.18 emu/g, and 0.33 Oe, respectively. Besides, significant ( p < 0.001) dose-dependent (250–1000 μg/mL) antibacterial and antibiofilm activities against the NDM-1-producing Gram-negative Escherichia coli (AK-33), Klebsiella pneumoniae (AK-65), Pseudomonas aeruginosa (AK-66), and Shigella boydii (AK-67) bacterial isolates warranted the as-synthesized EGCG-MINPs as a promising alternative for clinical management of chronic bacterial infections in biomedical settings. In addition, molecular docking experiments revealed that compared to free Fe 3+ and EGCG alone, the EGCG-MINPs or Fe-EGCG complex possess significantly high binding affinity toward HSA and hence can be considered as promising biocompatible nanodrug carriers in in vivo drug delivery systems.

“…Silver nanoparticles (AgNPs) synthesis and applications have taken an enviable position amongst various nanomaterials available. This may be due to the ability of AgNPs to be used as an antibacterial agent (depending on the material deployed for its synthesis) 30 – 32 , and its localized surface plasmon resonance property (LSPR), which can be tuned for the sensing/detection of various analytes 33 – 35 . The ability of AgNPs to serve the aforementioned roles is highly dependent on the precursor materials used for its fabrication, the synthesis conditions, storage conditions etc.…”

Herein, the synthesis of a biocompatible silver nanoparticles (AgNPs), for colorimetric detection of toxic mercury (II) ion (Hg2+), is reported. Phenolic-rich fraction of Asystasia gangetica leaf was extracted and used as a reductant of silver salt, all within the hydrophilic konjac glucomannan (KgM) solution as stabilizer, at room temperature (RT). The bioactive components of Asystasia gangetica phenolic extract (AGPE), as elucidated with a (UHPLC-MS-QTOF-MS), revealed plethora of phenolic compounds, which can facilitate the reduction of silver salt at ambient conditions. Sparkling yellow colloidal solution of KgM-AgNPs was realized within 1 h, at RT, having a UV–vis maximum at 420 nm. KgM-AgNPs was characterized using UV–vis, Raman and (FTIR), TEM, SEM, EDS, XRD, TGA/DTG. TEM and FESEM images showed that KgM-AgNPs were spherical, with particle size distribution around 10–15 nm from TEM. The KgM-AgNPs biocompatibility was investigated on mouse L929 fibrobroblast and rat erythrocytes, without any harmful damages on the tested cells. In aqueous environment, KgM-AgNPs demonstrated good detection capacity toward Hg2+, in a Hg2+ concentration dependent fashion, within 3 min. Absorbance ratios (A360/A408) was linear with Hg2+ concentrations from 0.010–10.0 to 10.0–60.0 µM, with an estimated (LOD) of 3.25 nM. The probe was applied in lake water sample, with satisfactory accuracy.
