Gelatin-based sprayable foam as a skin substitute.

Area of Science:

• Biomaterials science
• Wound healing technologies
• Antimicrobial materials

Background:

• Effective wound management requires dressings that provide protection and promote healing.
• Current wound dressings may have limitations in conforming to irregular surfaces or providing antimicrobial properties.

Purpose of the Study:

• To evaluate the physical and antimicrobial properties of a novel gelatin-based spray-on foam bandage.
• To assess its suitability for application on various skin wound types.

Main Methods:

• Aqueous foam formulation developed for aerosolized spray application.
• Characterization of physical properties including adherence, matrix formation, and evaporative water loss reduction.
• Antimicrobial testing against Gram-positive bacteria, Gram-negative bacteria, and fungi.

Main Results:

• The spray-on foam effectively conforms to and covers uneven wound surfaces.
• It dries into a stable, adherent three-dimensional matrix, significantly reducing evaporative water loss.
• Demonstrated significant antimicrobial activity against Gram-positive, Gram-negative, and fungal microorganisms.

Conclusions:

• The developed gelatin-based spray-on foam bandage exhibits promising physical and antimicrobial characteristics.
• It represents a potentially advanced option for wound care, offering improved coverage and infection control.
