The custard apple peel nanoparticles may be manufactured by extracting custard apple peels in a solvent, spraying the custard apple peel extracts into boiling water under ultrasonic conditions to produce a first mixture, sonicating the mixture, stirring the mixture, and drying the mixture to obtain custard apple peel nanoparticles. In an embodiment, the custard apple peel may be peel of. In an embodiment, the custard apple peel nanoparticles may have improved antibacterial or antioxidant properties.

A method of preparing metal nanoparticles using an extract of desert truffles (Terfeziaceae) includes providing an aqueous solution including a metal salt; and combining an extract of Terfeziaceae with the aqueous metal salt solution to produce the metal nanoparticles. The metal salt can be silver nitrate (AgNO) and the metal nanoparticles can be silver nanoparticles. The metal nanoparticles can have a mean diameter in the range of from about 5 nm to about 100 nm. The silver nanoparticles can be used as an antimicrobial agent and/or an anti-parasitic agent.
