Abstract

Poly (lactide-co-glycolide) (PLGA) coupled with methoxy poly (ethylene glycol) (mPEG) or chlorin e6 (Ce6) was synthesized using the Steglich esterification method. PLGA-linked mPEG (PLGA-mPEG), PLGA-linked Ce6 (PLGA-Ce6), and Fe₃O₄ were utilized to constitute multifunctional PLGA nanoparticles (∼160 nm) via the multi-emulsion W₁/O/W ₂ (water-in-oil-in-water) method. The photo-sensitizing properties of Ce6 molecules anchored to PLGA nanoparticles enabled in vivo luminescence imaging and photodynamic therapy for the tumor site. The encapsulation of Fe₃O₄ allowed high contrast magnetic resonance (MR) imaging of the tumor in vivo. Overall, PLGA nanoparticles resulted in a significant tumor volume regression for the light-illuminated KB tumor in vivo and enhanced the contrast at the tumor region, compared to that of Feridex® (commercial contrast agent).
