Abstract:
Thiourea based dipodal receptor (R1) was developed and characterised using 1H NMR, 13C NMR and
mass spectroscopy. Using re-precipitation method, R1
was processed into organic nanoparticles (N1), evaluated
its sensor activity in aqueous medium. The prepared N1
were characterized using Transmission Electron Microscopy (TEM) which shows 30 nm size. Dynamic Light
Scattering (DLS) was employed for calculating average
particle size. To imply N1 as sensor, its interaction with
various anions was studied and found reasonable selectively for Br¢
ions with detection limit of 3.79 nM. For
real life analysis, involving determining Br
¢
from environmental samples, proposed sensor works successfully with
accuracy more than 95%.
