In the present research, ZnSe nanoparticles were synthesized by aqueous method at pHs of 8, 10.2, 11.2 and 12.2 and were grown by microwave irradiation at the times of 0 and 6 minutes. In the synthesis process, Se and Zn ions sources were added to each other at the presence of thioglycolic acid as capping agent . Antibacterial properties of these nanoparticles have been carried out by using disc diffusion method (in solid Muller-Hinton-Agar culture) against the Escherichia coli and Pseudomonas aeruginosa gram-negative bacteria in the loading volume of 140 µL of nanoparticles. Generally, results showed that by increasing the radiation time from 0 to 6 min, bacterial growth inhibition zone increased for Pseudomonas aeruginosa bacteria in compare with Escherichia coli bacteria; the highest antibacterial activity is devoted to the cases of pH=10.2 and 11.2, and these samples can be introduced as new agents in the field of nano-biotechnology applications.
