• Infectious Diseases

Background:

• Bacterial infections remain a leading global cause of mortality.
• Emergence of antibiotic resistance necessitates novel therapeutic strategies.
• Traditional antibiotics face challenges due to widespread drug resistance.

Purpose of the Study:

• To review responsive antibacterial materials as alternatives to conventional antibiotics.
• To categorize responsive materials based on intrinsic and extrinsic stimuli.
• To discuss the biomedical applications of these materials in therapeutics and devices.

Main Methods:

• Review of scientific literature on responsive antibacterial materials.
• Categorization of materials based on stimulus-response mechanisms (pH, enzyme, ROS, light, temperature, magnetic fields).
• Discussion of applications in medical treatments and devices.

Main Results:

• Responsive materials demonstrate significant potential in combating resistant bacteria.
• Materials can be activated by various intrinsic (e.g., pH, ROS) and extrinsic (e.g., light, magnetic fields) stimuli.
• These materials offer a promising approach to mitigate side effects associated with traditional antibiotics.

Conclusions:

• Responsive antibacterial materials represent a viable alternative to overcome antibiotic resistance.
• Further research and development are crucial for clinical translation and optimization.
• Future perspectives highlight challenges and opportunities in designing advanced antibacterial systems.
