“…And when the concentration of Ag‐PDA NPs was at 2–64 μg/mL, there was no significant effects on cell viability in MH−S cell line by CCK‐8 assay, demonstrating the desirable biocompatibility. Previous studies reported that silver nanoparticles were nontoxic at low concentrations [15] . And our results were consistent with the previous research, indicating polydopamine decorated silver nanoparticles are promising candidates for drug carriers due to their biocompatible properties.…”

Tuberculosis (TB) is among the top ten causes of death worldwide. The emergence of multidrug-resistant (MDR) TB has been challenging to cure TB patients and control the airborne transmission. To ensure the effectiveness of rifampin (RF) in the treatment of MDR TB infection, new and safe silver nanoparticles were used in combination. In this study, polydopamine decorated silver nanoparticles (Ag-PDA NPs) were synthesized under mild conditions in which antituberculosis drug RF was loaded. Subsequently, the antibacterial activity of different ratios of Ag-PDA NPs/RF against MDR strains of Mycobacterium tuberculosis (M. tuberculosis) was evaluated by minimum inhibitory concentration (MIC) tests. MIC results showed a synergistic interaction between Ag-PDA NPs and RF, and the optimal antibacterial effect against MDR strain of M. tuberculosis was at the mass ratio of 2 Ag-PDA NPs : 8RF. In addition, RF loaded Ag-PDA NPs (RF@Ag-PDA NPs) were constructed and characterized. The results indicated that RF@Ag-PDA NPs might be considered as promising nano drugs to inhibit the growth of MDR strain of M. tuberculosis and keep the potency of RF in clinical practice.

Thermoplastic polyurethanes (TPUs) bear tunable chemistry offering the possibility to develop a rich palette of physio‐mechanical properties, making the materials suitable for various fields of application. The great variety in TPUs properties comes from the choices of the monomers and the reaction conditions. Herein, the mechanical properties of the developed TPUs are tailored, while fine‐tuning the hard and soft segment molar ratio, as well as the reaction conditions. TPUs are synthesized from 4,4′‐methylenebis(phenyl isocyanate), poly(tetrahydrofuran), and 1,4‐butanediol, and their thermal and mechanical properties are fully characterized. The sample with the most appropriate mechanical properties that are suitable for catheter fabrication, is selected for the biomedical application. Quaternary ammonium salt is synthesized, and 0.5 mol% is incorporated in the TPU to confer antibacterial properties to the material while preserving its mechanical strength. The microbiological tests reveal the antibacterial effect of the developed materials against Staphylococcus aureus and Pseudomonas aeruginosa, as well as 80% SiHa cell viability, after 72 h of exposure, as part of the performed cytotoxicity studies. Finally, TPUs catheter prototypes fabrication is also proposed, applying an extrusion or injection molding approach for the production of biomedical devices with desirable mechanical properties.
