Silicone Materials Having Antimicrobial Efficiency
Silicones are commonly used in the healthcare and medical sectors due to its excellent biocompatibility and versatility in properties. However, one main concern for materials developed for use in these sectors is the prevention of hospital-acquired infections (HAIs). Therefore, to circumvent the risk of HAIs, an antimicrobial silicone-based material is necessary to reduce the infections caused by pathogens to patients.
The technology on offer is a scalable, cost-effective antimicrobial silicone composite material comprising of cellulose/silver and silicon as the matrix. Silver (Ag) nanoparticles are first deposited onto cellulose fibers through a simple process to prevent the migration of the silver particles. Upon solidfication, the cellulose/silver composite is next mixed with silicon to form the final silicone composite material. By incorporating silver into the material as the antimicrobial agent, a stable and strong antimicrobial material can be obtained for healthcare and medical applications.
Technology Features, Specifications and Advantages
The technology utilizes an environmentally friendly and simple deposition method of Ag particles onto cellulose.
Some features of the modified silicone composite include:
- No intensive migration of Ag nanoparticles, hence longer antimicrobial effect
- Strong antimicrobial activity against Gram-positive and Gram-negative bacteria
- Improved mechanical properties compared to neat silicone
Potential applications of this antimicrobial silicone composite material include (but are not limited to):
- Medical devices - blood, respiratory and urinary catheters, intestinal tubes, plugs, implants
- Consumer goods - household items, children's toys, other accessories
- Reduces prevalence of HAIs in medical facilities
- Cost-effective and scalable solution
- Increased durability of silicone material
