Effect of nanotization on therapeutic activities of biomolecules: synthesis and characterization

The bioactive organic nanoparticles were synthesized by precipitation-dialysis method from their corresponding bulk forms. The morphology and average particle size of the synthesized nanoparticles were characterized by scanning electron microscope (SEM) and dynamic light scattering (DLS) techniques. The nanotization decreases the particles size by 2-20 times with a narrow range of distribution and also considerable change in the shape. Further, the nanoparticles (1-10) and their bulk forms (1B-10B) were evaluated for in vitro antioxidant, anti-inflammatory and antimicrobial activities. The biological assay data revealed that new organic nanoparticles showed enhanced biological activity compared to their corresponding bulk forms. This may be due to increase in the surface area and decrease in the particles size after nanotization.
