A Vehicle‐Free Antimicrobial Polymer Hybrid Gold Nanoparticle as Synergistically Therapeutic Platforms for Staphylococcus aureus Infected Wound Healing

Advanced Science, Journal Year: 2022, Volume and Issue: 9(14)

Published: March 10, 2022

Abstract Pathogenic bacteria infection is a serious threat to human public health due the high morbidity and mortality rates. Nano delivery system for delivering antibiotics provides an alternative option improve efficiency compared conventional therapeutic agents. In addition drug loading capacity of nanocarriers, which typically around 10%, further lowers dose that pathological are exposed to. Moreover, nanocarriers not eliminated from body may cause side effects. These limitations have motivated development self‐delivery systems formed by self‐assembly different this study, vehicle‐free antimicrobial polymer polyhexamethylene biguanide (PHMB, with bactericidal anti‐biofilm functions) hybrid gold nanoparticle (Au NPs, photothermal therapy (PTT)) platform (PHMB@Au NPs) developed. This exhibits excellent synergistic effect enhance Staphylococcus aureus under near‐infrared irradiation. Furthermore, results showed PHMB@Au NPs inhibit formation biofilms, quickly remove promote wound healing through PTT in model vivo, even mediate transition macrophages M1 M2 type, accelerate tissue angiogenesis. will promising value as highly effective agents patient management.

Published: Jan. 1, 2022

The repair of infected bone defects with irregular shapes is still a challenge in clinical work. Infected are faced several major concerns: the complex defects, intractable bacterial infection and insufficient osseointegration. To solve these problems, we developed personalized MXene composite hydrogel scaffold GelMA/β-TCP/sodium alginate (Sr2+)/MXene (Ti3C2) (GTAM) photothermal antibacterial osteogenic abilities by 3D printing. In vitro, GTAM scaffolds could kill both Gram-positive Gram-negative bacteria NIR irradiation due to excellent effects MXene. Furthermore, rat marrow mesenchymal stem cells were mixed into bioinks for bioprinting. cell-laden printed showed biocompatibility formation ability depending on MXene, crosslinked Sr2+, β-TCP. vivo, implanted S. aureus-infected mandible rats irradiation. accelerate healing regeneration, play synergistic roles effects.
