Background: The use of nanoparticles has markedly increased in biomedical sciences. The silver nanoparticles
(AgNPs) have been investigated for their applicability to deliver chemotherapeutic agents in cancer treatment. However, the
existing chemical and physical methods of synthesizing AgNPs are considered inefficient and expensive, and are fraught
Objective: Natural products have emerged as viable candidates for nanoparticle production, including the use of Terfezia
boudieri (T. boudieri), a member of the edible truffle family. Accordingly, our goal was to synthesize AgNPs using the
aqueous extract of T. boudieri (green synthesized AgNPs). Since certain infectious agents are linked to cancer, we further
investigated their potential as anti-cancer and antibacterial agents.
Methods: The physico-chemical properties of green synthesized AgNPs were analyzed by UV-Vis, FT-IR, XRD, SEM and
TEM. In addition, their potential to inhibit cancer cell (MCF-7 and AGS) proliferation as well as the growth of infectious
bacteria were investigated. Synthesis of AgNPs was confirmed by the presence of an absorption peak at 450nm by spectroscopy.
Results: The size of nanoparticles ranged between 20-30nm and exerted significant cytotoxicity and bactericidal effects in a
concentration and time dependent manner compared to T. boudieri extract alone. Interestingly, synthesis of smaller AgNPs
correlated with longer synthesis time and enhanced cytotoxic and bactericidal properties.
Conclusion: This study shows that synthesis of smaller AgNPs correlated with longer synthesis time and enhanced cytotoxic
and anti-bacterial effects.
