A Highly Fluorescent Pyrene-Based Sensor for Selective Detection Of Fe3+ Ion in Aqueous Medium: Computational Investigations

Host-guest interactions of coumarin-based 1,2-pyrazole using analytical and computational methods: Paper strip-based detection, live cell imaging, logic gates and keypad lock applications

“…Generally, information about molecules' three-dimensional charge distributions is provided by the molecular electrostatic potential surface analysis. MEP exhibits major characteristics such as changes in dipole moment, size, electronegativity, electron density, partial charges, and chemical reactivity sites found in the molecule [ 43 ]. The regions on a molecule that are open to an electrophilic assault can therefore be effectively detected by MEP analysis since it displays the regions which are electron-rich and deficient in the molecules.…”

A benzimidazole-based ‘turn-on’ fluorescent probe for highly sensitive detection of Fe3+/2+: synthesis, performance, DFT calculations and applications

“…9 Therefore, fluorescent probes have attracted widespread attention as highly selective and low-cost metal ion detection tools. [10][11][12] Fluorescent probes that are currently used for detecting iron are based on the principle of fluorescence quenching luminescence, [13][14][15][16] as shown in Table 1. There are few studies on fluorescence-enhanced probes but all are for the detection of either Fe 3+ or Fe 2+ .…”

Pilot Study on the Visualization of Latent Fingerprints and Naked Eye Detection of Hg2+ and Zn2+ Ions in Aqueous Media Using Ninhydrin-Based Thiosemicarbazone

“…Calculations of the Detection Limit and the Binding Constant. The equation 3σ/K, where σ is the standard deviation of the blank measurement and K represents the slope obtained from the plot of absorbance vs metal ion concentration, 24 was used to compute the detection limit. At 425 nm, the range between 2 × 10 −6 and 9.33 × 10 −6 M showed a better linear characteristic between the absorbance and Hg 2+ ion concentration (R 2 = 0.9873).…”
