摘要：Abstract In this work, we report antibacterial activity of 3,6-di(pyridin-2-yl)-1,2,4,5-tetrazine (pytz) capped Pd(0) nanoparticles (TzPdNPs). The TzPdNPs were characterized by transmission electron microscopy (TEM) and powder X-ray diffraction techniques (PXRD). The antibacterial properties of TzPdNPs were studied using Gram-positive B. subtilis and Gram-negative E. coli by the plate count method. The antimicrobial activity of this TzPdNPs shows that the microbial growth has been fully inhibited only for Gram-positive B. subtilis bacteria. Morphological changes obtained by transmission electron microscope observation show that TzPdNPs can cause leakage and chaos of intracellular contents.
