Schiff base derived bis-organosilanes: Immobilization on silica nanosphere and Cu2+ and Fe3+ dual ion sensing

Immediate detection of Co2+ by a phthalazine‐based colorimetric chemosensor

“…Sigma-Aldrich provided the other chemicals. 1 H and 13 C NMR spectra were recorded on a Varian spectrometer. A Perkin Elmer UV-vis spectrophotometer was employed to acquire the UV-vis data.…”

“…The design of simple and convenient chemosensors that can detect metal ions has attracted considerable attention owing to the pivotal roles of these ions in the natural environment. [1][2][3][4][5][6][7] Of the metal ions, cobalt performs a vital task in vitamin B12 and plays a principal role in various metabolisms and the synthesis of metalloproteins. [8][9][10][11] However, excess accumulation of cobalt in the human body can have toxicological effects, such as reduced cardiac output, asthma and thyroid enlargement.…”

Tetrazole conjoined organosilane and organosilatrane via the ‘click approach’: a potent Mycobacterium tuberculosis enoyl ACP reductase inhibitor and a dual sensor for Fe(iii) and Cu(ii) ions

“…The Cu(II) ion is scrupulously involved in dopamine production, bone development, brain functioning, gene transcription, electron transfer catalysis, free radical scavenging, mitochondrial respiration, iron absorption, and elastin cross-linking. [25][26][27] Excess copper ions cause damage in the liver and kidney and may cause serious diseases such as Menkes and Wilson disease, Alzheimer's disease, prion diseases, and Indian childhood cirrhosis. [25][26][27][28][29][30] Meanwhile, iron is an essential component of heme and non-heme enzymes and is involved in oxygen metabolism, gene expression, cell metabolism, nerve conduction, electron transfer, regulation of osmotic pressure in cells and DNA synthesis.…”

[31][32][33] Disturbed iron content in the human body can lead to several diseases such as Huntington's, diabetes mellitus, anaemia, hypoimmunity, low blood pressure, organ dysfunction, tumorigenesis and heart attack.…”

Synthesis and Characterization of Antioxidant Biphenyl Appended 1,2,3‐Triazoles as Potential Chemo‐Sensor for Sn2+ Ions: Excellent Selectivity and Low Detection Limit

“…The invention and implication of sensors to monitor various analytes in the environment and biological systems is the new area of intrigue among researchers over other analytical methods due to operational simplicity, precise selectivity, rapid response, relatively low expense and easy operation. [23][24][25][26][27][28][29][30] Here, in the present work, we have synthesized and characterized biphenyl appended 1,2,3-Triazoles using click route. One derivative 4 a among triazoles has been explored for chemosensing properties by Ultraviolet and fluorescence spectroscopy.…”
