Isonicotinic acid hydrazide or isoniazid (INH) is one of the most commonly utilized drugs in the treatment of TB. Patients need to take 300 mg daily of INH for 6 months in combination with another anti-TB drug and tolerate several side effects of INH. On the other hand, the emergence of resistant strains of anti-TB antibiotics is one of the major problems in the treatment of this disease. So, antimicrobial drug delivery by nanofluids could improve the efficacy, and reduce the adverse effects of antimicrobial drugs. The purpose of this study was to perform a novel method to synthesize INH-conjugated multi-wall carbon nanotubes (MWCNTs) for more effective drug delivery, as well as, TB treatment.Methods: INH-conjugated functionalized MWCNTs were prepared, using a reflux system. The characterization of the obtained nano-drug was performed by the elemental analyses of total nitrogen, hydrogen, carbon and sulfur (CHNS), Raman spectroscopy, Fourier transform infrared (FTIR), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) methods. The nanofluid of nano-drug was prepared by the ultrasonic method, and the related antibacterial effect studies were carried out on the two strains of M.tb.Results: The antimicrobial effect of INH-conjugated MWCNTs was found to be much better at low concentr
