Additive printing of gold nanoparticles on paper substrate through office ink-jet printer

Abstract

The article reports the synthesis of the concentrated Gold Nanoparticles (AuNPs) ink and its printing on the paper substrate through Office Ink Jet printer. Initially, AuNPs were synthesized from the precursor Gold (III) Acetate through Ultrasonic Spray Pyrolysis. Ellipsoidal shaped AuNPs with a size distribution of below 50 nm were confirmed through TEM and DLS measurement. Maximum absorbance wavelength of AuNPs measured through UV-vis spectroscopy was 532 nm. Further, the AuNPs ink was prepared through the rotavapour and filtered upto the Au concentration of 600 ppm determined through ICP-OES. The AuNPs printed patterns on the photo paper substrate were successfully printed and further analyzed with SEM.
