Display omitted Chitosan (Cs) is a biocompatible, biodegradable cationic polymer having the ability of targeted drug delivery. Vitamin E and C are not synthesized in our body thus, when encapsulated within a carrier system these vitamins in combination with/alone can be utilized for their anti-cancer potentials. The present investigation was conducted to develop a stable nanoparticle based formulation encapsulating antioxidants (Vitamin E, catechol) and silver nanoparticles synthesized from Hibiscus rosa-sinensis (HRS) petal extracts within a chitosan matrix. The prepared nanoformulations were characterized using Field emission scanning electron microscopy (Fe-SEM), X-ray diffraction (XRD) and Attenuated Total Reflection Fourier Transform Infrared spectroscopy (ATR-FTIR). They were further tested for their antioxidant potentials using DPPH assay, hydrogen peroxide scavenging assay, nitric oxide scavenging assay and ferrous antioxidant reducing potential assay. The nanoformulations were found to be highly hemocompatible and showed high encapsulation efficiency up to 76%. They also showed higher antioxidant activity than their base materials. Further, their anti-cancer efficacy was observed against MCF-7 breast cancer cells having IC50 values of 53.36±0.36μg/mL (chitosan–ascorbic acid–glucose), 55.28±0.85μg/mL (chitosan–Vitamin E), 63.72±0.27μg/mL (Chitosan–catechol) and 58.53±0.55μg/mL (chitosan–silver nanoparticles). Thus, the prepared formulations can be therapeutically applied for effective and targeted delivery in breast cancer treatment.
