Claim 7:
8. A process of making a chitosan (CS)-doped Strontium oxide (SrO) nanocomposite, consisting of;
mixing water and a strontium chloride hexahydrate and stirring the mixer for 2 hours to make a solution of the strontium chloride hexahydrate;
forming a precipitate of a strontium chloride hexahydrate nanoparticle in solution by adjusting a pH of the solution of strontium chloride hexahydrate to a specific pH by adding sodium hydroxide solution for 2 hours and stirring;
collecting a pellet strontium chloride hexahydrate nanoparticle by centrifuging a strontium chloride hexahydrate nanoparticle in solution;
making a powder of strontium chloride hexahydrate nanoparticles by heating the pellet of the strontium chloride hexahydrate nanoparticle at 120° C. for 24 hours;
preparing a strontium chloride hexahydrate nanoparticle solution using the powder of strontium chloride hexahydrate nanoparticles in distilled water with various concentrations of a chitosan the specific pH using a specific basic solution to create a CS-doped SrO nanocomposite; and
inhibiting a bacterial growth by adding the CS-doped SrO nanocomposite in a bacteria in an infected cell.
