ABSTRACT
In recent times, nanotechnology has gained enormous attention, particularly in the branch of pharmacological science in which particles are reduced to nanoscales and found to be more sensitive than their traditional counterparts. Firstly, synthetic concoctions and physical techniques have been used; nevertheless, the identification of adverse effects on human health has increased significantly. Nowadays, green synthesis is widely used for the synthesis of nanoparticles. This breakthrough is particularly beneficial in reducing the toxicity induced by conventional methods. Plant metabolites and natural products are used in green strategies to synthesize nanoparticles for therapeutics and other uses.
Moreover, various plant-based carotenoid and algae extracts have synthesized many metallic nanoparticles. These studies have opened the way for using plant-based carotenoid extracts in developing nanoparticles since they reduce the need for reducing and stabilizing agents. Herein, we discussed green-synthesized metallic nanoparticles from flora and algae and their uses in various fields. Pharmacological features such as their anticancer, antibacterial, and antioxidant properties, prompted the team to write this chapter to explain various metal-based nanoparticles synthesized utilizing plants and algae.
