In this work, chitosan/polycaprolactam (PCL-CS) nano-complex was synthesized and their micelles were formed as self-assembled amphiphilic nano-compartments. These micelles were utilize for drug delivery after loading quercetin (QU) as chemotherapeutic agent and delivery potency of this nano-complex was investigated. This nano-complex was also functionalized with folic acid (FA) in order to targeting delivery of nano-carrier to cancer cell lines. This foure dimensional nano-complex was successfully characterized based on UV-vis, FT-IR, DLS, and TGA analytical devices to confirm the synthesis. Drug loading was estimated 21.5% in final nano-carrier. In vitro drug release study was applied to investigation of QU release in PBS that was exhibited high potency of nano-complex in controlled drug release. Cell viability of assay was implemented to determination of biocompatibility, bioavailability and therapeutic potency of nano-complexes on different cancer and normal cell lines. Micelles demonstrated safety levels for 24 and 48 h post-treatment incubation and FA receptor mediated uptake of chitosan/polycaprolactam/folic acid/quercetin (PCL-CS-FA-QU) was exhibited excellent efficiency on inhibition of cancer cells.
