Easy and rapid chemosensing method for the identification of accumulated tin in algae: a strategy to protect a marine eco-system

Abstract

A simple and potent chemosensor AFL has been successfully developed to recognize Sn2+ selectively in marine algae or more specifically seaweed as they are in huge risk due to marine...

Recent advances in tin ion detection using fluorometric and colorimetric chemosensors

“…In 2022, Sahoo and co-workers designed and synthesized an anthracene-based chemosensor for sensing of Sn 2+ ions in a H 2 O : CH 3 CN (1 : 1, v/v, pH 7.2, 10 mM Tris–Cl buffer) solution. 110 When Sn 2+ was added to the probe solution, the absorbance intensities at 312 nm and 404 nm decreased considerably. Furthermore, upon addition of Sn 2+ , the increase in the emission intensity (31-fold) was noted due to the Sn 2+ induced inhibition of the PET process and the activation of the CHEF effect.…”

Detection of exposed phosgene in household bleach: development of a selective and cost-effective sensing tool

“…The easily detectable alteration of their physical or chemical properties upon interaction with selective analytes makes them a smart device for widespread application due to their easy operation, uncomplicated instrumentation, high selectivity and sensitivity, on-the-spot rapid detection, and so on. [31][32][33][34][35][36][37][38][39][40] Most uorescent chemosensors consist of an oxime as a recognition site that shows 'turn-on' uorescence as it turns into a nitrile upon interaction with phosgene. 41 Hence, it is signicant to use this oxime functional group attached to the uorophore to construct a 'turn-off' chemodosimeter with unique dimer formation in the presence of phosgene.…”

Fabrication of a luminescent chemosensor for selective detection of Al3+ used as an adjuvant in pharmaceutical drugs

“…High selectivity and sensitivity, cost-effectiveness, rapid response, portability, and on-spot detection ability make the fluorescence technique highly advantageous over other methods. [30][31][32][33][34][35][36][37] In this work we have developed a simple and proficient probe (NAN) for selective recognition and estimation of Al(III) ions in different kinds of over-the-counter drugs and supplements as they are some of the major sources of Al accumulation in the body, which plays a role in the development of Alzheimer's disease (AD) along with different neurological disorders.…”
