This contribution presents a review of Ultrasonic Spray Pyrolysis (USP) as a technique for the synthesis of gold nanoparticle (AuNPs). The synthesis mechanism involved the preparation of the precursor solution with insoluble gold salts and the study of the process parameters i.e. chemical (initial concentration, solubility and purity of the precursor) physical (ultrasonic frequency, droplet size, evaporation and sintering temperature) and kinetic (flow rate of carrier and reducing gases). In the second step the USP parameters` effects on AuNPs` morphology (size and shape), final concentration of AuNPs, purity and crystal structure, functional characteristics (stability, degree of agglomeration and absorption spectra of AuNPs) have been studied extensively. We would like to introduce AuNPs` future applications, which could be in printed electronics with conducted patterns.
