Abstract
AbstractThiourea 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 %.
