 This study produced Trastuzumab-targeted ecoflex nanoparticles, NPs, loaded with Dossetaxyl to target her two positive breast cancer cells. The NPs were characterized for size, zeta potential, drug loading, and release behavior. The NPs were found to be effective at delivering Dossetaxyl to her two positive cells, resulting in increased cytotoxic activity. This suggests that these NPs could potentially be used as a more effective form of chemotherapy for her, two positive breast cancer patients. This article was authored by J.
