More than 95% of the total protein (BSA) can be encapsulated and released from folic acid nanoparticles having size between 200 and 300 nm.
Release of BSA and carrier folic acid can be controlled by changing the concentration of crosslinking salt.
Similar release patterns of protein and carrier folic acid suggest that particle is formed by FA-protein association.
Release behavior of both folic acid and protein is dependent on salt concentration in the release medium.
Release behavior of drug from folic acid nanoparticles is same irrespective of molecular weight of drug.
