Dr. Gunjan Bisht Thapa, Assistant Professor of Department of Chemical Science and Engineering, and Dr. Bhupal G. Shrestha of Department of Biotechnology along with a group of B. Tech. students of Biotechnology, Kathmandu University, gota paper entitled “Synthesis, Characterization, and Study of In Vitro Cytotoxicity of ZnO-Fe3O4 Magnetic Composite Nanoparticles in Human Breast Cancer Cell Line (MDA-MB-231) and Mouse Fibroblast (NIH 3T3)” published in Nanoscale Research Letters (springer open) peer-reviewed journal.

This paper deals with the synthesis, characterization and in vitro cytotoxicity study of magnetic composite nanoparticles synthesized by ex situ conjugation of synthesized ZnO nanoparticles and Fe₃O₄ nanoparticles. The magnetic composite nanoparticles contain key properties of both nanoparticles viz. inherent selectivity towards cancerous cell and superparamagnetic nature for targeted localization, on a single system.
