Fig. 3From: Multifunctional TPP-PEG-biotin self-assembled nanoparticle drug delivery-based combination therapeutic approach for co-targeting of GRP78 and lysosomeCytotoxicity test. The cell viability of the Ru-1, TPP-PEG-biotin, and Ru-1@TPP-PEG-biotin SAN show negligible cytotoxicity. The cell viability of Ru-1@TPP-PEG-biotin SAN in a MCF-7 cells and b HepG2 cells under the light condition. c The cell viability of Ru-1 in HepG2 cells under dark condition, d The cell viability of TPP-PEG-biotin in HepG2 cells under light condition. Light dose: 660 nm, 30 mW/cm2, 20 min. The data were expressed as Mean ± SD, n = 3 independent experimentsBack to article page
