Smart bacteria-responsive drug delivery systems (DDSs) offer a promising solution for implantable biomaterial infections. These DDSs autonomously release antibacterial agents at infection sites, addressing antibiotic resistance and improving treatment efficacy.
Area of Science:
- Biomaterials Science
- Infectious Diseases
- Drug Delivery Systems
Background:
- Implantable biomaterials increase bacterial infection risks.
- Antibiotic resistance and recurrent infections limit current treatments for peri-implant infections.
Purpose of the Study:
- To review recent advances in bacteria-responsive drug delivery systems (DDSs) for combating implant-associated infections.
- To categorize these DDSs based on their distinct trigger mechanisms.
Main Methods:
- Literature review of stimuli-responsive biomaterials for antibacterial applications.
- Categorization of DDSs by trigger modes: physical stimuli, virulence factors, host immune responses, and combinations.
Main Results:
- Smart DDSs can autonomously and precisely release antibacterial agents at infection sites.
- Various trigger modes enable tailored drug release kinetics.
Conclusions:
- Bacteria-responsive DDSs represent a significant advancement in treating implant-associated infections.
- These smart systems are poised to become a leading antibacterial therapy approach.
