AI Article Synopsis
- - Imine-linked pyridine-coupled (ILPC) receptors were created and analyzed for their absorption and fluorescence characteristics using both experimental and theoretical methods.
- - These receptors were turned into organic nanoparticles (ONPs) and combined with gold nanoparticles (AuNPs) to selectively identify iodide ions, showing a very low detection limit of 1.4 nM without interference in water.
- - This study marks the first successful use of ONPs-AuNPs for detecting iodide in a nanomolar range in water, demonstrating its application in measuring iodide levels in urine samples.
Article Abstract
Imine-linked pyridine-coupled (ILPC) receptors have been synthesised and characterised. The absorption and fluorescence properties of these receptors have been explored through a combination of experimental and theoretical studies. The ILPC receptors are processed into organic nanoparticles (ONPs) and then decorated with gold nanoparticles (AuNPs) for the selective recognition of iodide. The selective recognition behaviour is authenticated with the changes in fluorescence spectra, low detection limit (1.4 nM) and no interference in aqueous systems. The present investigation represents the first example of nanomolar detection of iodide in aqueous medium using organic-inorganic hybrid nanoparticles (ONPs-AuNPs). The probe has been utilised successfully for the detection of iodide content in urine samples.
