Abstract
Aim: To develop and characterize doxorubicin-loaded sodium selenite nanoparticles (SSNP-DOX) and their surface attachment with cetuximab (mAb-SSNP-DOX).Methods: SSNP-DOX was formulated by gelation and then conjugated with cetuximab to form mAb-SSNP-DOX. Characterization included DLS, SEM, TEM, DSC, Raman spectroscopy and XRD. In vitro, the kinetics of doxorubicin release and cytotoxicity in MCF-7 breast cancer cells were investigated.Results: The zeta potential for SSNP-DOX and mAb-SSNP-DOX was -14.4 ± 10.1 mV and -27.5 ± 7.28 mV, with particle sizes of 181.3 nm and 227.5 nm, respectively. The formulation intensity was 89.7% for SSNP-DOX and 100% for mAb-SSNP-DOX, with PDI values of 0.419 and 0.251, respectively. SEM and TEM showed that mAb-SSNP-DOX was smooth and spherical. The DSC analysis revealed exothermic peaks at 102.44°C for SSNP-DOX and 144.21°C for mAb-SSNP-DOX, along with endothermic peaks at 269.19°C and 241.6°C, respectively. Raman spectroscopy showed a higher intensity for mAb-SSNP-DOX. The XRD study showed different peaks for each formulation. Both followed zero order kinetics for doxorubicin release. Cytotoxicity studies showed significant effects and high apoptosis in MCF-7 cells for both formulations.Conclusion: The mAb-SSNP-DOX showed promising properties, more effective doxorubicin release and higher cytotoxicity against breast cancer cells compared with SSNP-DOX.
