Nanomolar detection of iodide in aqueous medium using organic-inorganic hybrid nanoparticles: application in urine analysis
journal contribution
posted on 2015-04-01, 00:00 authored by C A Huerta Aguilar, Hemant Sharma, P Thangarasu, N SinghImine-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.
