“…The binding stoichiometries of NHPyTSC toward Hg 2+ and Zn 2+ ions were assessed using Job′s plot method. 32 In an ACN/water (8:2, v/v) medium, equal concentrations (1:1, 1 × 10 −5 M) of the sensor NHPyTSC and Hg 2+ /Zn 2+ were collected. The concentration of NHPyTSC ranged from 0.1 × 10 −5 to 1 × 10 −5 M. A 1:1 stoichiometry of NHPyTSC-Hg 2+ and NHPyTSC-Zn 2+ complexes was confirmed by Job′s plot, which stated that the peak absorption intensity was seen at 0.5 mole fractions (Figure S10A).…”

Here, we described a cheap and effective chemosensor (NHPyTSC) that can distinguish Hg2+ and Zn2+ ions from other metal ions and evaluated this phenomenon using several spectroscopy techniques. With the addition of mercury and zinc ions, the proposed chemosensor in particular showed noticeable changes in color and absorption spectra. Additionally, by including EDTA in the NHPyTSC-Hg2+ and NHPyTSC-Zn2+ solutions, colorimetry readings can be reversed. We developed a molecular-scale sequential information processing circuit and presented the “writing–reading–erasing–reading” and “multiwrite” behaviors in the form of binary logic based on the great reversibility of this process. Moreover, by sequentially adding Hg2+, Zn2+, and EDTA, NHPyTSC imitates a molecular keypad lock and molecular logic gates. Density functional theory (DFT) investigations provided more evidence of the Hg2+ and Zn2+ ions′ ability to attach to NHPyTSC. The most interesting part of this work is that a study on the latent fingerprint detection of the powder compound revealed that NHPyTSC exhibits good adherence and finger ridge features without background stains. When compared to black and white fingerprint powders, it is discovered that the NHPyTSC powder produces results that are remarkably clear on the majority of surfaces. This demonstrated their potential for real-world use, particularly in the area of criminal investigations.

Cellulose is a significant widespread sustainable resource on earth. With the development of nanotechnology, the interest of cellulose scientists has moved to the separation of nanocellulose from many plants and their application in technical applications. The promising properties of nanocellulose and related products are driving rapid progress in nanocellulose chemistry and engineering. In fact, nanocelluloses integrate cellulose's essential features with the exceptional properties of nanoscale materials. This paper summarizes modern knowledge in nanocellulose research and development. The methods for synthesizing nanocellulose and its functionalization procedures will be discussed after an introduction to the chemical structure and microfibrillar organization of nanocellulose in cellulose bundles with other components. Finally, the usage of nanocellulose for pollutant detection will be discussed.

“…Importantly, luminescence-based sensors can be further designed to attain a wide range of signaling "antenna" when the analyte covalently binds to the luminescent probe providing opportunities to monitor the concentrations of the target within a short time. This antenna can be observed through changes in the signal's intensities, wavelength, lifetime, and chirality [28][29][30][31][32].…”

“…When the target analyte binds to the receptor, an immediate change to the emission occur where emission intensity may be enhanced or quenched making 'off-on' or 'on-off' sensors as illustrated in Scheme 1. Variations to the emission spectra may occurs through various mechanisms including PET, Ligand-tometal charge transfer (LMCT), or metal-to-ligand charge transfer (MLCT) [30][31][32][33][34]. Several studies reported that the LMCT involves electronic transitions from the localized orbitals in the conjugated linker to a metalcentered orbital and is highly sensitive to the ionic size and the coordination geometry of the linker [30][31][32][33][34][35][36][37].…”

The substrate N1, N3, N5 -tris(2-hydroxyphenyl)benzene-1,3,5-tricarboxamide (Sensor A) was prepared in the reaction of 1,3,5-benzenetricarboxylic acid (trimesic acid) and o-aminophenol in ethanol. The prepared organic sensor fulfills the chemiluminescent requirements including luminophore, spacer, and suitable binding receptor that distress the probe's luminescent features, providing selective and sensitive detection of mercury and iron ions in aqueous solutions. The sensor selectively detects mercury and iron ions in a water matrix containing various metal ions including sodium, calcium, magnesium, zinc, and nickel. Strong and immediate binding was observed between mercury ions and the substrate at pH 7.0 with a binding affinity toward Hg (II) enhanced by nine folds higher than that observed for iron sensor binding affinity, which makes the substrate a distinctive luminescence sensor for mercury detection at ambient conditions. The sensor shows a linear response toward Hg (II) in the concentration range from 4.2 x 10-5 to 2.0 x 10-8 M with a limit of detection of 1.0 x 10-8 M. Further, Sensor A provides linear detection for iron ions in the range from 1.5 x 10-3 to 1.5 x 10-8 M. The measured adsorption capacity of Sensor A toward mercury ions ranged from 1.25 to 1.97 mg/g and the removal efficiency from water samples reached 98.8% at pH 7.0. The data demonstrate that Sensor A is an excellent probe for detecting and removing mercury ions from water bodies.
