Fabrication of MnFe₂O₄-CuInS₂/ZnS Magnetofluorescent Nanocomposites and Their Characterization.

ABSTRACT: Magnetofluorescent nanocomposites (MFNCs) providing a single nanoscale platform with multimodal properties are gaining momentum in biological manipulation, biomedical imaging and therapy. In this work, we report the preparation of MFNCs integrating MnFe₂O₄ magnetic nanoparticles (MNPs), CuInS₂/ZnS quantum dots (QDs) and poly(ethylene glycol)-b-poly(lactide-co-glycolide) (PEG-PLGA) in a tetrahydrofuran (THF)/water solvent system. Through sonication and quick solvent displacement, multiple nanoparticles of each type are co-encapsulated within the hydrophobic core of PEG-PLGA micelles. The developed fabrication process is simple and fast. Moreover, due to the low toxicity of CuInS₂/ZnS QDs, the fabrication process is environmentally benign. The fabr
