Improved microbial growth inhibition activity of bio-surfactant induced Ag-TiO2 core shell nanoparticles

- TiO2 nanoparticles were synthesized by hydrolysis process and Ag nanoparticles were prepared by using hydrazine reduction method.
- Ag-TiO2 core shell nanoparticles were synthesized by reverse micelle method.
- Coatings of TiO2 shell leads to decrease the usage of silver particles and also it reduces the release of silver ions from the matrix.
- Optimum ratio of TiO2 particles: Ag atoms are needed for better antibacterial activity.
- Sodium alginate (Bio-copolymer) induced core shell nanoparticles results 100% cell growth inhibition toward Staphylococcus aureus.
