Title: Colorimetric acetone sensor based on ionic liquid functionalized drug mediated silver nanostructures

Abstract:

The current work reports the drug-mediated synthesis of silver nanoparticles (AgNPs) and its functionalization with ionic liquid(IL) for acetonedetermination. The rationale behind the selection of Augmentin drugs was the aromaticity in its structure and the functional groups attached. Theseproperties are not only supposed to work in the synthesis of the nanoparticles but also enhance their electron density.The nanoparticles were further coated with 1-H-3-methylimidazolium acetate IL, having conductivity and aromaticity in its structure.The synthesized nanoparticleshave been characterizedby different techniques such as FTIR, XRD, SEM,and EDX, etc.Colorimetric determination of acetone was done by using IL capped AgNPswith the assistance of NaCl solution and results were analyzed by UVVis spectrophotometry. Low cost, stable eosin dye work as a substrate and is consumed resulting in a color change from brown to transparent. Different parameters such as (concentrations, loading ofnanoparticles, time and pH, etc.) were optimized to get the best results of the proposed sensor.The sensor shows awide linear range of (1×10-8-1.6×10-6M), low limit of detection 1.87×10-7Mand limit of quantification 6.22×10-7Mwith an R2value of 0.999.The proposed sensor has been successfully appliedtodiabetic patient’s urine samples for acetone detection with a visible colorimetric change. It showed good sensitivity and selectivity towards acetone detection.
