Fecha de publicación: 20/05/2016 Fuente: WIPO "jalea real" The present disclosure is related to the use of metal nanoparticles, organometallic and metallic dendrites obtained through Royal Jelly, as bactericides. Said nanoparticles, organometallic and dendrites are based on any of the metals from the group that comprises: Silver, platinum, palladium, gold, rhodium, copper or zinc. Royal jelly is used as a reaction medium, acting as a reducing agent and stabilizer, in order to avoid the use of chemical solutions for the synthesis of the same. The bactericidal activity of these nanoparticles, organometallic and metal dendrites was tested against gram-positive and gram-negative bacteria, presenting the lowest Minimum Inhibitory Concentration (MIC) ever reported in the literature.
