The present study aims to investigate the bovine serum albumin nanoparticles (BSANP) with exosomes (Exo) for prolonged release of 5-Flurouracil (5FU) as an anticancer drug model. 5FU with Exo was loaded to BSANP (5FU.Exo@BSANP) and the system was characterized by FTIR, AFM and FESEM. Furthermore, 5FU.Exo and 5FU@BSANP were prepared and characterized to compare their release behavior with that of 5FU.Exo@BSANP. The binding properties examined via FTIR confirmed the formation of the above-mentioned systems. FESEM analysis of BSANP and 5FU.Exo@BSANP showed the spherical morphology with the average particle size 313±60 nm and 403±64 nm, respectively, while, 5FU.Exo had a cylindrical morphology with average particle size in width 200±36 nm. AFM results demonstrated the reduction of roughness in 5FU.Exo@BSANP. In addition, the release behavior indicated that sustained release of 5FU occurred when it was loaded to nanocarriers. However, the release of 5FU from 5FU.Exo@BSANP at pH 7.4 was slower than in the other systems. Furthermore, the kinetic model of all systems was followed by Korsmeyer-peppas with Fickian diffusion while 5FU.Exo@BSANP at pH 5.5 was zero order kinetic model. Moreover, MTT assay onto 4T1 cancer cell lines explored the significant cytotoxicity of 5FU.Exo@BSANP. Thus, the designed nanocarrier of Exo@BSANP is a promising system for sustained release of 5FU.  UR - https://www.nanomedicine-rj.com/article_251937.html L1 - https://www.nanomedicine-rj.com/article_251937_2a416194d59ef06e7ef4076eaff498db.pdf ER -
