“…The nanoparticles resulted in a minimum detection of 2.7 µM and 60 µM when observed by UV-Vis spectrophotometry and the naked eye, respectively. Within five minutes of incubation, the colour of the chlorophyll nanoparticles gradually changed from brown to light brown or colourless with the increases in mercury concentrations [117]. Compared to other Hg 2+ pigment sensors, this method has a higher LOD, which is less favoured for the detection of the smallest amounts of metals.…”

“…The Hg 2+ ions initially bind to the methyl groups on the surface of nanoparticles and form a methylmercury ([CH 3 Hg] + ) which is highly oxidative [116]. The oxidation of metallic silver to silver ion occurs with the reaction of Hg 2+ in the methylmercury, thus the colour of the nanoparticles changes from brown to colourless [117]. The nanoparticles resulted in a minimum detection of 2.7 µM and 60 µM when observed by UV-Vis spectrophotometry and the naked eye, respectively.…”

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.

“…The LOD of chlorophyll-AgNPs was determined to be 2.7 M and 60 M with UV-visible spectrophotometer and the naked eye, respectively, and a linear response extending from 0.1 M to 200 μM was observed. [194] Using AgNPs, a highly specific and sensitive colorimetric technique for detecting Hg 2+ ion from aqueous samples has been developed AgNPs. AgNPs were created via a chemical reduction technique with polyvinyl alcohol (PVA) serving as a stabilizing agent.…”

This review briefly emphasizes the different detection approaches (electrochemical sensors, chemiluminescence, surface‐enhanced Raman scattering), functional nanostructure materials (quantum dots, metal nanoparticles, metal nanoclusters, magnetic nanomaterials, metal oxide nanoparticles, polymer‐based nanomaterials, and carbonaceous nanomaterials) and detection mechanisms. Furthermore, the emphasis of this review is on the integration of functional nanomaterials with optical spectroscopic techniques for the identification of various biomarkers (nucleic acids, glucose, uric acid, oxytocin, dopamine, ascorbic acid, bilirubin, spermine, serotonin, thiocyanate, Pb2+, Cu2+, Hg2+, F−, peptides), and cancer biomarkers (mucin 1, prostate specific antigen, carcinoembryonic antigen, CA15‐3, human epidermal growth factor receptor 2, C‐reactive protein, and interleukin‐6). Analytical characteristics of nanomaterials‐based optical sensors are summarized in the tables, providing the insights of nanomaterials‐based optical sensors for biomarkers detection. Finally, the opportunities and challenges of nanomaterials‐based optical analytical approaches for the detection of various biomarkers (inorganic, organic, biomolecules, peptides and proteins) are discussed.

Silver nanoparticles (AgNPs) are well known for their exceptional properties and versatility in various applications. This study used andrographolide as a biochemical stabilizer to synthesize AgNPs (andro-AgNPs). The andro-AgNPs were characterized by using UV−vis spectroscopy, revealing a surface plasmon resonance peak at 440 nm. Fourier transform infrared spectroscopy was also used to confirm the presence of AgNPs. Transmission electron microscopy was used to investigate the morphology of andro-AgNPs, which showed a spherical shape with an average diameter of 18.30 ± 5.57 nm (n = 205). Andro-AgNPs were utilized as a colorimetric sensor to detect mercury ions (Hg 2+ ) in water, and the optimized detection conditions were evaluated using UV−vis spectroscopy with a linear range of 15− 120 μM. The limit of detection and the limit of quantification for Hg 2+ detection were found to be 11.15 and 37.15 μM, respectively. Furthermore, andro-AgNPs exhibited antibacterial properties against both Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria. The results imply that andro-AgNPs hold promising potential for future biomedical applications.
