Biological activities of synthesized silver nanoparticles from
Cardiospermum halicacabum L.B SUNDARARAJAN G MAHENDRAN R THAMARAISELVI B D RANJITHA KUMARI
The present study focuses on the green synthesis of silver nanoparticles using aqueous extract of
Cardiospermum halicacabum . AgNPs were confirmed by UV–Visible spectrophotometer analysis showed SPR at424 nm. FT-IR analysis revealed biomolecules capping of the AgNPs. XRD pattern of synthesized AgNPs was found in face-centered-cubic crystal structure and average crystal size was 23 nm. SEM analyses of the synthesized AgNPsdetermine the spherical shape and EDX spectra confirmed the presence of silver ions. DLS studies revealed that the synthesized AgNPs showed the average size as 74 nm and Zeta potential value of AgNPs was −34 mv. TheC. halicacabum leaf extract synthesized AgNPs efficiency were tested against different bacterial pathogens MTCC-426 Proteus vulgaris, MTCC-2453Pseudomonas aeruginosa , MTCC-96Staphylococcus aureus , MTCC-441Bacillus subtilis andMTCC-735Salmonella paratyphi , and fungal pathogensAlternaria solani andFusarium-oxysporum . The antioxidant ability of the AgNPs was tested and the results showed significant DPPH, hydroxyl and superoxide, radical scavenging activities.
