During the present study, we have evaluated magnetic chitosan as a potential drug delivery device, by specifically determining if chitosan could elute antibiotics in an active form that would be efficacious in inhibiting Staphylococcus aureus and Escherichia coli growth. We have demonstrated that the incorporation of cephalosporins of second, third and fourth generation into magnetic chitosan microspheres can possibly lead to an improved delivery of antibiotics in active forms, probably due to the inherent properties of chitosan.
