In this work, ZnO–Ag nanoparticles with a silver content of 0.1–50 at % have been fabricated by the exploding wire method. ZnO–Ag nanoparticles absorb visible light and destroy the model dye Rhodamine B. The introduction of silver into nanoparticles has made it possible to shift the main absorption edge to 1.59–2.74 eV. The determined optimal content of silver in nanoparticles of 12 at % has ensured the degree of Rhodamine B decoloration by 85% within 60 min of exposure to visible light and has completely stopped the growth of E. coli bacteria at a concentration of 15.6 µg/mL. In addition, nanoparticles containing 12 at % silver have sterilized a sample of natural water contaminated with microorganisms. The results obtained offer an efficient method for the synthesis of antibacterial nanocomposites with heterojunctions employing a high-performance technique for producing nanoparticles, namely, the exploding wire method.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324533088">Разработка новых материалов с антибактериальными свойствами является перспективным направлением в области исследования нанодисперсных систем. В настоящей работе наночастицы ZnO–Ag с содержанием серебра 0.1–50 ат. % получены электрическим взрывом проводников. Наночастицы ZnO–Ag поглощают видимый свет и разлагают модельный краситель родамин Б. Введение серебра позволило сместить край основного поглощения до 1.59–2.74 эВ. Определено оптимальное содержание серебра в наночастицах (12 ат. %), позволяющее обеспечить степень обесцвечивания родамина Б 85% в течение 60 мин облучения видимым светом и полностью остановить рост бактерий <italic>Escherichia coli</italic> в концентрации 15.6 мкг/мл. Кроме того, наночастицы, содержащие 12 ат. % серебра, стерилизовали пробу природной воды, загрязненной микроорганизмами.
