Silver triethanolamine-loaded PVB/CO films for a potential liquid bandage application

Area of Science:

• Biomaterials Science
• Wound Healing Research
• Nanotechnology

Background:

• Silver exhibits potent antibacterial properties but is prone to oxidation, reducing efficacy.
• Developing stable, effective silver-based wound dressings remains a challenge.

Purpose of the Study:

• To develop and evaluate a novel silver triethanolamine (ST) loaded PVB/CO solution as a liquid bandage.
• To assess the stability, physical properties, and in vivo efficacy of the ST-loaded liquid bandage.

Main Methods:

• Preparation of silver triethanolamine (ST) loaded PVB/CO solution.
• Evaluation of film transparency, stability under light exposure, tensile strength, elongation, and water vapor transmission rate (WVTR).
• Assessment of antibacterial properties and in vivo wound healing in a nude mouse model.

Main Results:

• The PVB/CO/ST formulation maintained high transparency after 12 months of light exposure.
• The liquid bandage demonstrated excellent mechanical properties, waterproofness, and prevented bacterial invasion.
• Wound healing was accelerated, and inflammation was reduced in ST-treated wounds in vivo.

Conclusions:

• The PVB/CO/ST solution is a stable, transparent, and effective liquid bandage.
• It offers significant advantages in wound care, including antibacterial protection and enhanced healing.
• This formulation shows potential as a promising therapeutic agent for treating minor trauma.
