Integrating magnetic nanoparticle technology with phytoconstituents enhances the potential for targeted drug delivery with minimal systemic toxicity and facilitates therapeutic outcomes. Methods: A Box-Behnken design was employed to optimize the CUR-PIP-F68-Fe3O4 NPs prepared by the co-precipitation method. Optimized formulation was evaluated for morphological characteristics, elemental composition, and magnetic properties. An in vitro cytotoxicity assay was conducted to observe the % viability of cells and to further calculate the IC50. Cellular uptake studies were investigated using confocal microscopy. Results: Results showed that the optimised nanoparticles possessed a particle size of 158.7 ± 0.057 nm, zeta potential of –30.3 ± 0.1 mV, and encapsulation efficiency of 98.85 ± 0.066%. Analysis by vibrational sample magnetometer revealed that magnetic saturation was 75.6 emu/g and 50.7 emu/g for bare Fe3O4 nanoparticles and drug-loaded magnetic nanoparticles, respectively. Scanning electron microscopy (SEM) depicted the morphological characteristics; elemental composition of synthesized magnetic nanoparticles was confirmed by energy dispersive X-ray (EDX) analysis by illustrating the presence of C (13.50 ± 0.30%), Fe (78.81 ± 1.23%), and O (7.69 ± 0.29%). The MTT assay and cellular uptake studies unveiled that CUR-PIP-loaded magnetic nanoparticles possess a synergistic cytotoxic effect and the highest drug uptake against the HCT-116 colon cell line. Conclusions: The combination approach of curcumin-piperine magnetic nanoparticles to HCT-116 cells enhanced the anticancer efficacy of the curcumin and further demonstrated the potential of this approach to conduct in vivo studies.
