Aqueous black carpenter ant extract (ABCAE) was used to synthesize silver nanoparticles (AgNPs). The ABCAE was rich in water-soluble compounds such as hydrophilic polypeptides that behaved as both reducing and stabilizing agents for generating AgNPs from Ag ion precursors. The diameter of the observed AgNPs was mostly in the range of 20-60 nm. The AgNPs were tested as an antibacterial agent for the growth inhibition of two pathogenic bacteria (Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 27661) and one common bacteria (Escherichia coli K12 ATCC 10798). Disk diffusion test showed that the AgNPs selectively inhibited the growth of P. aeruginosa but not for the other two species, suggesting the potential application of the green-chemically synthesized AgNPs as a selective antibacterial agent without harming other beneficial bacteria.
水黑 Carpenter 蚁提取物 (ABCAE) 被用于合成银纳米粒子 (AgNPs)。ABCAE 富含水溶性化合物，如亲水性多肽，它们既作为还原剂又作为稳定剂，从 Ag 离子前体生成 AgNPs。观察到的 AgNPs 的直径大多在 20-60nm 范围内。AgNPs 被测试为一种抗菌剂，用于抑制两种致病菌（铜绿假单胞菌 ATCC 27853、金黄色葡萄球菌 ATCC 27661）和一种常见细菌（大肠杆菌 K12 ATCC 10798）的生长。圆盘扩散试验表明，AgNPs 选择性地抑制铜绿假单胞菌的生长，但对其他两种细菌没有抑制作用，这表明这种绿色化学合成的 AgNPs 作为一种选择性抗菌剂具有潜在的应用价值，而不会对其他有益细菌造成伤害。
