... To understand surface chemical composition of modified bacterial cellulose, XPS is widely used [53][54][55][56][57][58][59][60][61][62]. We analyzed and compiled literature data related to the C 1s, O 1s and Ag 3d5/2 spectra of BCF, Ag NPs/BCF, SBCB and Ag NPs/SBCB and Ag NPs (Tables 1 and 2). ...

... It was shown [46,47] that during cellulose cultivation, thin primary layers are first formed and then new thicker secondary layers are formed on top, the density of which is not uniform due to a decrease in the concentration of the carbon source over time [48]. It was found that primary layers with a diameter of about 1.3 μm are present in the structures of the obtained BCF, which are at a distance of 4-5 μm from each other, forming areas with a low density of fibrils. ...

... It was found that primary layers with a diameter of about 1.3 μm are present in the structures of the obtained BCF, which are at a distance of 4-5 μm from each other, forming areas with a low density of fibrils. The distance between the primary layers is about 4.5 μm, which is in good agreement with the previously established data [49,50]. Analysis of BCF micrographs showed that there are secondary layers with a thickness of about 13 μm and a distance between them of 12.5 μm. ...

... Fig. 2 (d1) and Fig. 2 (d2) shown the C1s spectra of the CS and CS/GEL/PA-Na respectively. There were four bands at 287.0 eV, 285.9 eV, 284.9 eV and 284.1 eV, corresponding to C-H, C-C, C-N and C-O for CS, respectively (He et al., 2021;Li et al., 2021;Li et al., 2021Li et al., , 2021Novikov et al., 2021). Those bands; however, were shifted and found at 285.2 eV, 284.8 eV, 284.5 eV, 284.1 eV in CS/GEL/PA-Na. ...

... The scanning electron micrographs presented in figure 6 reveal the internal structure on the micron scale: Here, the layers of micro-sized tubes or 'microtunnels' described and rationalized by Gromovykh et al and exhibiting a similar periodicity, were clearly visible, figure 6(b) [20]. We found that these exhibit curvatures, depending on the location within the sample, figure 6(a). ...

... Эффективность используемых методов очистки натуральных мембран БЦ с использованием только NaOH находится на этапе критического осмысления и поиска эффективных подходов для улучшения очистки БЦ. Так, рассматриваются альтернативные решения одновременной очисткой и стерилизации путем обработки мембран БЦ сверхкритическим диоксидом углерода, а также с помощью холодной плазмы [17,18]. В своей работе мы показали, что нативные мембраны БЦ в срок 7 суток после имплантации вызывают местную воспалительную реакцию экссудативного типа, которая проявляется преобладанием в составе периимплантного инфильтрата полинуклеарных лейкоцитов с участием макрофагов, что наблюдалось при всех вариантах подготовки БЦ. ...

... Kurokawa et al. [5] reported that Monascus pigments possess great anticancer activity against murine 4T1 mammary carcinoma cell, and the cell viability reduced from approximately 50% to 5% when MP concentration increased from 300 to 400 µg/mL. Compared with free silibinin, an extraction from Silybum marianum seeds, the liposomal silibinin exhibited stronger cytotoxic activity against cancer cells [40]. The same trends are observed in propolis liposomes, which powerfully enhanced the cytotoxic effect on Hep-2 cells compared with the unencapsulated ones [26]. ...

... Nowadays, large amounts of silibinin powders can be easily prepared. However, recent reports have demonstrated that silibinin can also adopt conformations that are more complex such as liposomal forms [23] and emulsomes [24]. Furthermore, it can be confined in oil nanocapsules [25], adsorbed on magnetic nanoparticles [26], and form silibinin-metal ion complexes with interesting properties [27]. ...
