Microorganism-mediated drug delivery

Natural carrier systems existing in mammals have driven current researches to focus in designing new drug carriers with the aid of bionanotechnology. These natural carriers function by mimicking the various physiological entities to safely deliver drug to the intended sites. In this chapter, we have discussed about the development of microorganism and protein/peptide inspired and mimicking drug delivery system. These micro/nanocarriers are capable of targeting specific cells for efficient drug delivery. We have categorized the microorganisms as virus, bacteria, and fungus which have been extensively used for designing drug carriers. The functions and effectiveness of the individual microorganism are explained depending on their way camouflaging the therapeutic molecules. In addition, we have discussed about different protein macromolecules and peptide sequence coated drug nanoparticles that have been used for effective delivery system.
