Near-infrared mediated polymer-coated carbon nanodots loaded cisplatin for targeted care management of lung cancer therapy

The Cisplatin and its analogues are scarce for the second leading human health problem, cancer. Therefore, we have effectively engineered the PEGlyated carbon nanodots loaded with cisplatin PEG-CDs@Cis-Pt(IV) for targeted lung cancer therapy. The PEG-CDs@Cis-Pt(IV) confirmed by the electroscopic and spectroscopic methods. The in vitro cytotoxicity of the nanoparticles evaluated two lung cancers (A549 and HEL-299), and one non-cancerous cell line (HUVECs) were used in this study by using MTT assay. The nanoparticles are effectively killing cancer cells without affecting the nano-cancerous cells. Further, dual AO-EB fluorescent staining assay established the programmed cell death through cell morphological changes. Further, flow cytometry confirmed the induction of apoptosis by S phase arrest of the cancer cell cycle by the complexes. The results of our investigations also bear witness to CDs@Cis-Pt(IV)+NIR-NPs promising scope and potency care management for precise cancer therapy beyond platinum drugs.
