Fig. 3From: Anti-cancer effect of nano-encapsulated boswellic acids, curcumin and naringenin against HepG-2 cell lineScanning electron microscopy, a micrograph of the drug-loaded nanoparticles of precipitation method. The figure shows a micrograph of the drug-loaded NP (F2). NP were of spherical shape with a size distribution in approximate agreement with light scattering data. The smooth NP surface was free from void and poresBack to article page
