Gold nanoparticles (AuNPs) can be prepared in a number of chemical techniques, which are not environmentally friendly. Biosynthesis of nanoparticles by plant extracts is currently under exploitation. In this work, we describe an eco-friendly technique for green synthesis of AuNPs from AuCl4 solution using the Houttuynia cordata leaf extract as reducing agent. The AuNPs were characterized using UV-Visible spectroscopy, SEM, TEM, FTIR and AFM. The UV-Visible spectra indicate a strong plasma resonance that is located at 535 nm. The antibacterial activity of AuNPs was performed on various gram positive and gram negative bacteria. The AuNPs showed more inhibitory activity on gram negative than gram positive bacteria.
