PROCESS OF ATTAINMENT OF MICRON AND NANOSPHERES OF I POLISHED (AND – CAPROLACTONA) IN THE INCORPORATION OF

NOVELTY – The production of micro- and nanosphere form antimycobacteria compound comprises emulsification and spontaneous diffusion of solvent yielding poly(e-caprolactone) with incorporation of anti-tuberculosis agent isoniazide. The solution of polymer with isonaziazide is e.g. ethyl acetate is added dropwise to the aqueous solution of Tween 40 surfactant via a micro-syringe. The micro-emulsion after evaporation of the solvent is centrifuged and lyophilized to yield the microspheres. USE – In applied chemistry.

Main Application Field
