At a Glance
Researchers at Colorado State University have developed a novel silver metallogel having antimicrobial properties capable of improving silvers’ antimicrobial lifetime. The novel material is water soluble and does not contain any hazardous solvents. Moreover, the metallogel system is extremely versatile with potential application in wound dressings and solid scaffold systems.
Background
New antimicrobial materials are highly desirable due to the rise in antibiotic-resistant pathogens. Silver hydrogels represent a relatively novel biomedical application for antimicrobial wound dressing due to the intrinsic antimicrobial behavior of silver. Although these types of materials demonstrate an adequate level of antimicrobial activity, the silver nanoparticles suspended within the silver hydrogels exhibit toxicity, especially at relatively high concentrations.Â
Therefore, there is a need for better, more versatile materials having considerable antimicrobial properties and negligible toxicity.
Benefits
- Metallogel system is versatile material with extensive application
- Greater antimicrobial properties as compared to similar materials
- Unique amorphous and hygroscopic properties
- Does not contain hazardous solvents and is water-soluble
- Reversible gelation process
- Ability to apply material as a solid, liquid, or gel
- Increased lifetime of antimicrobial activity
Applications
- Silver based antimicrobial agents (topical application, bandages, solid scaffold systems)
- Wound dressings, wound care applications
- Biotechnological applications (e.g., antimicrobial)
- Ag-based antibacterial materials
