Abstract

Background: Chitosan nanoparticles have gained growing interest for nanomedicine, biomedical engineering and development of new therapeutic with improved bioavailability, increased sensitivity and specificity, and reduced toxicity. Objective: The aim of the present study is to synthesis of the chitosan nanoparticles for antimycobacterial applications. Methods: Chitosan were isolated from the shrimp shell. Tripolyphosphate (TPP) will be used to prepare chitosan nanoparticles by ionotropic gelation method. The size and morphology of the chitosan nanoparticle was analyzed by scanning electron microscope (SEM). The broth microdilution method is used to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of nanoparticle chitosan on strain M. tuberculosis H37Rv. Results: The SEM micrographs of the nano-magnetic chitosan showed that they were approximately uniform spheres and the rough surface morphology, have a solid dense cubical or rectangular structure. Using the broth microdilution susceptibility method, chitosan nanoparticle was found to have the antimycobacterial effects with a MIC value of 1200 μg/mL whilst MBCs value of 2400 μg/mL for M. tuberculosis H37Rv. Conclusion: The conclusion from the study was chitosan nanoparticle have potential as a source of lead compounds that may be developed further into antimycobacterial drugs.
