Less research has been done on using bioinspired DH-CdSNP to deliver anticancer medications. The amalgamation of plant extract and the DH-CdSNP could cause a paradigm shift in the cancer therapy approach. The findings revealed that the biosynthesized DH-CdSNP limited the growth of human breast and ovarian cancer cells. This property can be further investigated against a variety of additional cell lines to determine whether this property makes the DH-CdSNP a promising treatment alternative. The results obtained from these nanoformulations exhibit faster efficacy compared to traditional medications.
