Using cyclodextrins for wound healing applications has been explored extensively, with numerous promising prototypes developed — though none have reached commercial markets until now.

A breakthrough innovation by Jun Li at the National University of Singapore demonstrates a “smart multifunctional ROS-responsive supramolecular hydrogel.” This polymer is dynamically crosslinked through inclusion complexes formed between β-cyclodextrin and ferrocene.

Key Features

• Facilitates on-demand release of interleukin-4 (IL-4)
• Exhibits intrinsic antibacterial properties
• Reprograms macrophages from M1 (proinflammatory) to M2 (anti-inflammatory) phenotypes
• Addresses immune dysregulation characteristic of diabetic wounds

Clinical Outcomes

The composition significantly enhanced wound closure, collagen density, and angiogenesis. It reduced proinflammatory cytokines (IL-6 and TNF-α) while increasing anti-inflammatory cytokine IL-10 levels.
