Immunoengineering External Field Responsive Biomaterials for Tissue Repair and Regeneration

Area of Science:

• Biomaterials science
• Regenerative medicine
• Immunology

Background:

• Tissue defect repair involves complex biological processes including inflammation regulation, angiogenesis, and immune homeostasis.
• Effective repair strategies require precise spatiotemporal control over these dynamic processes.
• The immune microenvironment plays a critical role in successful tissue regeneration.

Purpose of the Study:

• To outline the dynamic biological requirements of tissue repair, emphasizing the immune microenvironment's role.
• To review the advantages and mechanisms of external field-responsive biomaterials (EFRBs) in regenerative medicine.
• To summarize recent advances in immunoengineering EFRBs for enhanced tissue repair and regeneration.

Main Methods:

• Literature review focusing on external field-responsive biomaterials (EFRBs).
• Analysis of EFRB structural features and response mechanisms to various stimuli (optical, magnetic, electrical, ultrasonic, thermal).
• Examination of EFRBs' regulatory effects on immune-related repair processes.

Main Results:

• EFRBs offer on-demand activation and unique physicochemical properties for tissue repair.
• Various EFRB formats (nanoparticles, scaffolds, hydrogels, microneedles) can modulate immune responses.
• Immunoengineering EFRBs shows significant potential for enhancing tissue regeneration.

Conclusions:

• EFRBs represent a promising strategy for precise control in tissue repair and regeneration.
• Modulating the immune microenvironment with EFRBs is key to improving therapeutic outcomes.
