This review focuses on SeNPs' antimicrobial action as well as the factors that influence their green production, such as pH, temperature, and precursor concentration, all of which affect their morphology, size, and stability. SeNPs' antimicrobial activity against a diverse range of bacteria, fungi, and viruses is extensively tested, with a focus on their capacity to battle drug-resistant infections and biofilms. The mechanisms of SeNPs' antimicrobial effect are investigated, including membrane disruption, reactive oxygen species (ROS) production, and interactions with cellular components. Furthermore, their antiviral characteristics and ability to alter immune responses highlight their medicinal applications.

The CHZnO-NPs formulation was then characterized to determine the morphology, size, crystallinity, elemental composition and vibrational properties. Upon characterization, CHZnO-NPs were studied for their cytotoxic effect against the breast cancer cell line (MDA-MB-231). The successful biosynthesis of CHZnO-NPs was initially confirmed visually by the changes in the mixture color, from light-yellow to white cloudy. The best CHZnO-NPs formulation selected was F3, which possessed 10 mg/mL of colchicine. Formulation (F3) had the smallest mean particle diameter of 43.77 nm and the lowest zeta potential of −19.60 mV. It also had 92.21 ± 0.012 % encapsulation efficiency and 20.86 ± 0.005 % drug loading.
