Stimuli-responsive nanoplatforms for antibacterial applications

Area of Science:

• Nanomedicine for Infectious Disease
• Emerging Technologies

Background:

• Increasing bacterial resistance poses a global public health threat, necessitating novel antibacterial strategies.
• Conventional nanodrug delivery systems face challenges like slow release, poor accumulation, and limited biofilm penetration.

Purpose of the Study:

• To review recent advancements in endogenous and exogenous stimuli-responsive nanoplatforms for antibacterial applications.
• To discuss strategies for enhancing therapeutic efficacy and minimizing side effects in combating bacterial infections.

Main Methods:

• Review of endogenous stimuli-responsive nanoplatforms utilizing infection microenvironments (pH, enzyme, redox, toxin).
• Review of exogenous stimuli-responsive nanoplatforms, focusing on light-responsive nanoparticles and photothermal-triggered systems.

Main Results:

• Stimuli-responsive nanoplatforms effectively address limitations of conventional nanoparticles in treating bacterial infections.
• Endogenous systems leverage specific microenvironments for targeted drug release, while exogenous systems offer controlled delivery, notably light-triggered approaches.

Conclusions:

• Stimuli-responsive nanoplatforms represent a promising frontier in nanomedicine for tackling bacterial infections, including biofilms.
• Further development in designing these advanced systems can significantly improve treatment outcomes and reduce adverse effects.
