Background: The selective delivery of drugs to their targets prevents their possible side effects; hence, the development of selective transport systems is considered extremely promising.In the present study, we aimed to develop a drug delivery system for targeting bacteria.Methods: Functionalization of apoferritin with WGA, as a bacteriarecognizing lectin, was conducted.Afterwards, the complex was loaded with ampicillin.The affinity of the conjugate to Gram-positive bacteria, B. subtilis, was evaluated by anisotropic AgNPs conjugated with this complex, and its interaction with the bacteria was also assessed.Results: The drug-delivery capabilities of the composite were evaluated.Results from the disk diffusion assay revealed that its bactericidal activity is 10-fold greater compared to free antibiotics.The effectiveness of the bactericidal effects of ampicillin-loaded ferritin was also confirmed in whole blood.Conclusion.Lectin-conjugated and ampicillin-loaded apoferritin can be considered as effective drug delivery systems for targeting bacteria.
