Sumario:[Image: see text] We propose a novel multifunctional nanocarrier system for targeted drug delivery for lung cancer theranostics. Oxygenated particles (OPs) synthesized with an oxygen-encapsulating carboxymethyl cellulose shell were used as a platform to deliver oxygen to the hypoxic tumor microenvironment. The OPs synthesized could also be conjugated with ligands (e.g., antibodies) to target cancer cells expressing the corresponding antigens to deliver a drug, doxorubicin. In vitro testing of functionalized OPs showed increased efficacy of doxorubicin against the proliferation of lung cancer cells. Both confocal fluorescence imaging and darkfield microscopy hyperspectral imaging validated the OP complex and its efficient targeting of specific cells to deliver the therapeutic. The nanocarrier platform developed can also serve as a diagnostic imaging reagent as demonstrated by darkfield microscopy. Results show that the theranostic OPs developed with multifunctional modalities enabled targeted drug delivery with improved efficacy and tracking of drug delivery vehicles by imaging.
