Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

Advanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

[Antimicrobial peptides].

Wiadomosci lekarskie (Warsaw, Poland : 1960), 2007
For many years, attention has been focused on adaptive immunity as the main antimicrobial defense system. The discovery of antimicrobial peptides turned this point of view. In general, these peptides act on microorganisms directly by disrupting the structure of the microbial cytoplasmatic membranes and indirectly acting on immune system.
