Green synthesis of nanoparticles is inexpensive and environmentally safe, herein we report green approach for the synthesis of Ag, Fe2O3, CuO nanoparticles by using Asparagus Racemosus plant to detect carboxylate vapours. Synthesized Ag, Fe2O3, CuO nanoparticles were taken in 1:1:1 ratio and PANI (polyaniline) was added in ratio 5:1 to form Ag-Fe2O3-CuO–PANI nanocomposite. Synthesized Ag-Fe2O3-CuO-PANI were characterized by XRD, FESEM and FTIR whose size was in the range of 16–60 nm. Further, a low cost and portable optical fibre-based sensor was developed using Ag-Fe2O3-CuO-PANI nanocomposite which was coated on unclad optical fibre, in which change in refractive index after exposure to carboxylic acid vapours was measured for 25-200 ppm concentration for Apple vinegar, Vinegar and Lemon juice. Carboxylic acid vapours of Apple vinegar showed the maximum response with optimized Ag-Fe2O3-CuO-PANI nanocomposite thickness 11.39 µm on the clad, length of 10 mm with U-shaped sensing probe with 8 mm bent radius.
