The present application discloses a method of synthesizing metal-based cationic surfactants and further their usage as anti-tumor and anti-bacterial agents. For the synthesis, selenius acid is mixed with sulfonamide to form sulfonammonium hydrogen selenites. Cobalt and Platinum hydrogen selenite dehydrate were then synthesized, and refluxed with sulfonammonium hydrogen selenites to form the disclosed Cobalt/Platinum ammonium hydrogen selenite complexes. Both complexes were mixed with cyclodextrin oligosaccharide to form nanoparticles, which were tested for anti-tumor/cancer and anti-bacterial effects.
