Novelty Au Nanoparticles with Different Nano Sizes as an Acidity Sensor

The amazing wide range, applications of gold nanoparticles corresponding to excellent optical and electronic properties enhance utilization Au NP as PH sensor. Gold were synthesized in simple rapid Turkevich method accomplish sensing technologies covalent or non-covalent, bonds formation causes, aggregation the target substance. characterization was studied using XRD, UV-spectroscopy SEM. XRD indicate polycrystalline. Nanoparticles with two different sizes according reducing agent amount obtain 20 30 nm. Optical energy gap calculated for both particle size find it (2.13) eV 30nm (2.33) 20nm.Scanning Electron Microscope showed spherical shape particles. test performed investigate efficiency Np’s sensor that is found be results more nm due its rough surface. Which a fantastic tool measurement device pH soil, food, other puncture-worthy applications.
