Copper ferrite heterojunction coatings empower polyetheretherketone implant with multi-modal bactericidal functions and boosted osteogenicity through synergistic photo/Fenton-therapy

Recent advances in engineered polymeric materials for efficient photodynamic inactivation of bacterial pathogens

“…(b) Schematic of NIR-triggered synergistic antibacterial mechanism of CuFe 2 O 4 /GO; (c – d) Photographs of S. aureus and E. coli bacterial colonies treated by different samples with/without NIR irradiation; (e – f) The relative antibacterial percentages of S. aureus and E. coli ; (g – h) SEM morphologies of bacteria treated with different samples (the red arrows indicate the membrane shrinkages).

“…As a result, the osteogenesis and osseointegration between the implant and bone tissue have been strengthened through photo-triggered therapeutic ions delivery ( Fig. 7 b–h) [ 110 ].…”

Unveiling the interplay between homogeneous and heterogeneous catalytic mechanisms in copper–iron nanoparticles working under chemically relevant tumour conditions

“…The nanocatalyst was stored at 4 C for further use. CuFe nanocatalysts were synthetized using bovine serum albumin (BSA) as template 27,89 and ethylene glycol (EG) as a solvent to modulate particle size. 90 The abundance of nucleophile functional groups in the BSA (-COO-, -NH 2 ) can chelate the metal ions (Cu 2+ , Fe 3+ ) and serve as starting point to growth the nanostructure.…”

A hemostatic keratin/alginate hydrogel scaffold with methylene blue mediated antimicrobial photodynamic therapy

“…The protocols were based on the previous studies. 33,34,[46][47][48][49] Gram-positive Staphylococcus aureus (S. aureus) and Gramnegative Escherichia coli (E. coli) were grown for 24 hours in LB medium under aerobic conditions at 37 1C. Bacterial suspensions produced by diluting overnight cultures in LB medium to a cell density of 10 6 CFU mL À1 were seeded on LB agar with a sterile swab for the antimicrobial patch assay.…”
