ABSTRACT
This study developed folic acid (FA) conjugated chitosan (CS) encapsulated rutin (R) synthesized palladium nanoclusters (Pd NCs) for NIR triggered and folate receptor (FR) targeted triple-negative breast cancer (MDA-MB 231 cells) treatment. R-Pd NCs exhibited flower-shaped particles with an average size of <100 nm. FA-CS encapsulation concealed the flower shape of R-Pd NCs with a positive charge. The XRD spectrum confirmed the cubic crystalline structure of Pd. The FA conjugation on CS improved the cellular uptake of R-Pd NCs in MDA-MB 231 cells was confirmed by TEM. FA-CS-R-Pd NCs (+NIR) treatment was considerably inhibited the MDA-MB 231 cells proliferation evidenced by cell viability, fluorescent staining, and flow cytometry analysis. Further, in vitro hemolysis assay and in Ovo model confirmed the non-toxic nature of FA-CS-R-Pd-NCs with or without NIR radiation. Hence, this study concluded that FA-CS-R-Pd NCs can be applied for the treatment of drug-resistant breast cancer.
