Abstract
- [Display omitted] • BSA coated Pt nanoparticles was applied as both radiosensitizer and drug carrier. • In terms of morphology, nanoparticles appeared to be homogenous and monodispersed. • The results disclosed that designed nanoplatform due to the presence of Pt and BSA had ability to kill cancer cells effectively. Bovine serum albumin (BSA) coated platinum (Pt) nanoparticles (Pt@BSA NPs) were synthesized, followed by the conjugation of an anticancer drug (MTX) with the aim of chemoradiation therapy. The physical and chemical properties of Pt@BSA-MTX were evaluated by DLS, FESEM, STEM, UV–Vis and XRD. A release study was performed in the presence and absence of the proteinase K enzyme. In terms of morphology, nanoparticles appeared to be monodispersed and spherical. The size of nanoparticles was 7.4 ± 1.4 nm. Release behavior of Pt@BSA-MTX depended significantly on enzyme presence which accelerated and promoted the release of MTX. The improved chemoradiation was demonstrated in vitro using MTT, colony formation and apoptosis assays on mouse breast carcinoma cells (4T1). It was concluded that the combination of a nanoradiosensitizer with a chemotherapeutic agent resulted in superior anticancer activity after X-ray exposure. [ABSTRACT FROM AUTHOR]
