Rajkumar, Andras Sapi, Gitishree Das, Trishna Debnath, AbuZar Ansari, Jayanta Kumar PatraAbstractSilver nanoparticles (AgNPs) possesses a number of exceptional pharmaceutical properties and applications as compared with other types of metallic nanoparticles. Currently, AgNPs was biosynthesized using aqueous extract of Zea mays L. (corn flour) powder. Further, the effect of concentration of reagents, extract, temperature and time of synthesis was also studied along with the cytotoxicity and radical scavenging potential. UV–vis spectra of AgNPs gave a surface plasmon resonance at ~420 nm. The absorption peak became sharp with the increase in time. AgNPs with monodi...
