“…A high‐resolution XPS spectrum in the Ag 3d region was acquired from the bio‐AgNP sample (Figure (b)) in order to identify the valence state of the sample. Peaks were observed at binding energies of 373.5 ± 0.1 eV and 367.5 ± 0.1 eV, and were attributed to Ag 3d 3/2 and Ag 3d 5/2 , respectively; the nearly ±6 eV splitting of the 3d doublet of Ag indicated the presence of the Ag 0 state in the bio‐AgNPs . From the XPS analysis, however, it was not possible to determine whether metal oxide particles as well as metallic Ag particles were present or metallic particles were covered with a thin layer of oxide or both situations co‐existed.…”

In the current work, we followed a green chemistry route to prepare and characterize the silver nanoparticles (AgNPs) using Syzygium aromaticum (clove) extract at room temperature. Suitably, the clove extract acted as a reducing agent as well as a capping agent, and these reactions occurred rapidly. The formation of the AgNPs was confirmed by the observation of the distinct absorption peak at a wavelength of 418 nm using ultraviolet–visible (UV–Vis) spectroscopy, and a morphological study confirmed the uniform distribution of the optimally spherical nanoparticles. Fourier transform infrared spectroscopy (FTIR) results indicated the methoxy and allyl functional groups of eugenol of the clove extract to be responsible for the bioreduction of silver ions and for the stabilization of the resulting nanoparticles (flavonoids). We also found the AgNPs to be effective catalysts of the degradation of three pollutant organic dyes viz., 4‐nitrophenol, methylene blue and rhodamine B, in the presence of excess NaBH4. The antibacterial and antifungal activities of the bio‐synthesized AgNPs were also explored. Overall, the results suggested the potential use of clove extract as a resource for the synthesis of AgNPs having a broad range of possible commercial and biomedical applications.

“…38 It has been reported that Lys and TA formed a compound in both solution and LBL films onto the substrate. 39,40 In our case, the growth of multilayer was primarily ascribed to the interaction between Lys and TA, where the TA attached onto GO and GO was integrated into the coating with TA. This hypothesis can be further proved by the designed control experiments.…”

Dental implants have great potential in the global market, around $3.7 billion in 2015, which will increase to $7 billion in 2023 with an annual increase rate of 8.2%. Incorporating antibacterial and osteogenic agents into implants is helpful to make the dental implants successful, which can be endowed by coatings. In recent years, graphene oxide (GO) and its composite materials have shown advances in the biomedical field. Lysozyme (Lys) and tannic acid (TA) are naturally derived, with promising antibacterial and osteogenic properties as well. In the present study, the strong antibacterial and enhanced osteogenic multilayer coating is fabricated using the facile and controllable layer by layer (LBL) technique to integrate GO, Lys, and TA. The thickness of coating exhibited a continuous growth with the deposited process as proved from UV−vis and ellipsometry data, and the physical properties of the coating, such as wettability, roughness, and stiffness are well characterized. The coatings exhibited the synergic effect on the killing bacteria, both Gram-negative bacteria and Grampositive bacteria represented by E. coli and S. aureus, respectively, and enhancing osteogenesis of dental pulp stem cells (hDPSCs), showing the potential application on coatings of dental implants. Thus, the strategy applied here will inspire the design and development of dual functional surfaces for the success of implanted dental surface in future.

“…There are several published studies on Ag-embedded multilayer systems. 71–78 These studies presented results of an antibacterial effect, but only for a maximum of 48 h. In contrast, by dint of long-term tests carried out under flow conditions, antimicrobial activity could be demonstrated for at least eight days in the case of two Ag-multilayers. This is of significance when considering incorporation into indwelling medical devices, which are susceptible to colonization by different bacterial strains, 79–81 and post-surgical implant-infections.…”

Tailored antimicrobial activity and long-term cytocompatibility of plasma polymer silver nanocomposites

The deposition of coatings enabling antibacterial properties in combination with cytocompatibility remains a challenge for biomaterial applications, such as in medical devices. Silver is one of the most utilized antibacterial surface components, due to its efficacy and extensive applicability. In this work, silver-containing plasma polymer nanocomposites (single layer and multilayers) were developed and tested, with a focus on cytotoxicity and bactericidal function, on the NIH3T3 mammalian cell line as well as Gram-negative ( Pseudomonas aeruginosa) and Gram-positive ( Staphylococcus aureus) bacterial strains. The data demonstrate that a tuneable Ag release is required, allowing sufficient antimicrobial activity while retaining appropriate cytocompatibility over the entire testing period of up to eight days.
