Production Of Hand Sanitizer Using Aloe Vera And Silver Nanoparticles As An Active Agent

Ali Khumaeni, Ana Qona'ah, Syifa Avicenna, Iis Nurhasanah


The synthesis of colloidal silver nanoparticles was performed using a pulsed laser ablation technique. Laser ablation, unlike chemical techniques, can produce high-purity silver nanoparticles without any chemical deformation making them suitable for use as a hand sanitizer. In an experiment, a high-purity silver metal was immersed in a polyvinylpyrrolidone (PVP) liquid. The silver plate in the liquid was then bombarded using a 1064 nm Nd: YAG laser. Silver nanoparticles were successfully produced in PVP solution with a color change from transparent to yellow or brownish yellow. Silver nanoparticles have a spherical shape with a nanoparticle size of around 13 nm. Silver nanoparticles have an LSPR resonance peak at 402 nm, which is a great potential as hand sanitizers because of the size of the article on the nanoscale, so they can easily kill annoying microbes. The hand sanitizer product using the active ingredient aloe vera and silver nanoparticles has been tested on Escherichia coli bacteria for 60 seconds, resulting in the percentage of simplo bacteria killing of 98.091% and Duplo of 98.778%.
