Recently, the eco-friendly production of silver nanoparticles (AgNPs) has become a focal point for researchers. In India, the quest for cost-effective, non-hazardous compounds suitable for reducing and stabilizing AgNPs has been limited. This study explores the synthesis of AgNPs using Elettaria cardamomom seed extract. We evaluated the efficiency of silver ion (Ag+) reduction and AgNP formation from an aqueous AgNO3 solution combined with the cardamom seed extract. Characterization of the AgNPs was carried out through UV-vis spectroscopy, XRD, SEM, EDAX, and FTIR. This research presents a practical and efficient strategy for AgNP production. A formulation using readily available 1 mm aqueous AgNO3, known for its accessibility and therapeutic properties, was created with cardamom seed extract serving as both a capping and reducing agent. Within 30 minutes, the silver ions were reduced to AgNPs, resulting in a change from golden to dark brown-reddish tint. Various analytical techniques, including UV-vis spectroscopy and Fourier-transform infrared spectroscopy, were employed for characterization. This study introduces an affordable, robust, and renewable method using E. cardamomum seeds for AgNP synthesis, which is entirely eco-friendly and devoid of toxic chemicals. AgNPs hold promise for applications in cancer treatment and diagnosis, setting them apart from other noble metals. [ABSTRACT FROM AUTHOR]
