Popis: This study presents the development of a sustainable production process of environmentally benign silver nanoparticles (AgNPs) from aqueous root extract of Rhodiola imbricata (RI) and Withania somnifera (WS) for mitigating environmental pollution and investigating their potential applications in agriculture and biomedical industry. RIWS-AgNPs were characterized using several analytical techniques (UV-Vis, DLS, HR-TEM, SAED, EDX and FTIR). The antioxidant and anticancer activity of RIWS-AgNPs were estimated by DPPH and MTT assay, respectively. UV-Vis and DLS analysis indicated that equal ratio of RIWS-extract and silver nitrate (1:1) is optimum for green synthesis of well-dispersed AgNPs (λ
