This study analyzed the growth, collaboration, citation trends, and emerging topics in nanoparticle-based vaccine and adjuvant research (NVAR) from 1977 to 2023, using data from the Scopus database. The field showed a steady growth rate of 7.53% per year. Leading researchers Jaafari, M.R. and Alving, C.R. contributed significantly to the field, with 24.22% of publications and 38.92% of total citations coming from the United States. International collaboration was very strong, particularly between the US, UK, Germany, China, and France. Key research topics include nanoparticles, immunotherapy, COVID-19, and vaccines with a focus on SARS-CoV-2 and malaria. Emerging topics include vaccine adjuvants, mRNA, and neutralizing antibodies. This study emphasizes the importance of ongoing collaboration and interdisciplinary efforts to advance the field of NVAR.

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.
