The kinetics of vancomycin adsorption on nanodiamonds is described by a pseudo-second-order equation with close parameters for both types of nanodiamonds. The kinetics of vancomycin-nanodiamond complex formation is described by a pseudo-first order equation. Methods of radioactive indicators and IR spectroscopy are used to find that a part of vancomycin is firmly bound to the surface of nanodiamonds and is not removed by washing. The amount of firmly bound matter is found to be three times greater for the complexes with negative nanodiamonds. However, the retention strength of vancomycin on positive nanodiamonds was higher and its content practically did not change during desorption for 10 days. Both types of complexes have the same antimicrobial properties against Staphylococcus aureus. The totality of the obtained data confirms the assumption that the formation of hydrogen bonds with water molecules plays a key role in the adsorption and retention of vancomycin on the surface of nanodiamonds.</p></abstract><trans-abstract xml:lang="ru"><p>Получены адсорбционные комплексы ванкомицина с детонационными наноалмазами, имеющими положительный и отрицательный заряд поверхности. Кинетика адсорбции ванкомицина на наноалмазах описывается уравнением псевдо-второго порядка с близкими параметрами для обоих типов наноалмазов. Кинетика образования комплекса ванкомицин-наноалмаз описывается уравнением псевдо-первого порядка. Методами радиоактивных индикаторов и ИК-спектроскопии было найдено, что часть ванкомицина прочно связывается с поверхностью наноалмазов, и не удаляется при промывке. Количество прочно связанного вещества оказалось в три раза больше для комплексов с отрицательными наноалмазами. Однако прочность удерживания ванкомицина на положительных наноалмазах была выше и его содержание практически не менялось при десорбции в течение 10 сут. Оба типа комплексов обладают одинаковыми антимикробными свойствами по отношению к золотистому стафилококку. Совокупность полученных данных подтверждает предположение о том, что образование водородных связей с молекулами воды играет ключевую роль в адсорбции и удержании ванкомицина на поверхности наноалмазов.</p></trans-abstract><funding-group xml:lang="ru"><funding-statement>Министерство науки и высшего образования Российской Федерации (075-00277-24-00).
