Sprayable, antimicrobial and immunoregulation hydrogel loading exosomes based on oxidized sodium alginate for efficient wound healing at skin graft donor sites and health detection.

Skin grafting techniques are widely used for large burns, trauma, and various acute and chronic wounds, contributing greatly to the repair of traumatic tissue. However, donor site repair and regeneration are often neglected, resulting in infection and delayed healing. Therefore, it is crucial to reduce the rate of donor site infection and improve the speed and quality of healing.

Flexural vibrations and resonance of piezoelectric cantilevers with a nonpiezoelectric extension.

A piezoelectric cantilever (PEC) is a flexural transducer consisting of a piezoelectric layer [e.g., lead zirconate titanate (PZT)] bonded to a nonpiezoelectric layer (e.
