Abstract
Research in the fields of physics, chemistry, and engineering is all facing
more important challenges as a result of the rapid development of nanotechnology. The
green synthesis of metallic nanoparticles opened the door for improvements and
protections to be made to the environment by lowering the amount of harmful
chemicals used and avoiding the biological dangers that were present in biomedical
applications. Simple, fast, and environmentally friendly, plant-mediated production of
metal nanoparticles is rising in popularity. We show an easy and environmentally
friendly way to make silver nanoparticles using biomolecules found in an aqueous
extract of the leaves of the plant Kalanchoe gastonis-bonnieri. No other chemicalreducing or stabilizing agent is needed in this way. The reaction is carried out in an
aqueous solution in a process that is benign to the environment. This chapter examines
the anti-oxidant, diabetic, inflammatory, cancer, and cytotoxic properties of silver
nanoparticles that were generated utilizing the aqueous extract of the leaves of the plant
Kalanchoe gastonis-bonnieri. The results of the investigation are presented and
discussed in this chapter.
