Eco-friendly synthesis of metal nanoparticles using plant extract plays a vital role in nanotechnology. This study aimed to produce silver nanoparticles (SNPs) in an eco-friendly manner using leaf extract of Ulmus wallichiana Planch. When the leaf extract was treated with AgNO 3 , the colour changed from yellowish to dark brown, indicated the formation of SNPs. The obtaining SNPs were predominantly spherical, crystalline and a mean size of 54 nm. FTIR spectrum evidenced that plant's biomolecules acted as reducing agent. The antibacterial activity of SNPs was assessed against Gram positive (Staphyllococcus aureus) and Gram negative (Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae) bacteria and highest activity was found to be exerted at 1 mg/mL SNPs against P. aeruginosa (17.63 mm). They also showed profound antioxidant activity against DPPH. Ulmus mediated synthesis of SNPs is eco-friendly, non-toxic and cost effective with good antibacterial and antioxidant effect and can be used in biomedical applications. Rezumat Sinteza ecologică a nanoparticulelor metalice folosind extracte de plante joacă un rol vital în industria nanotehnologiilor. Acest studiu a urmărit biosinteza nanoparticulelor de argint (SNP) într-un mod ecologic, folosind extractul foliar de Ulmus wallichiana Planch. După tratarea extractului cu AgNO 3 , culoarea s-a modificat de la galben la maro închis, indicând formarea nanoparticulelor. SNP-urile obținute au fost predominant sferice, cristaline și au prezentat dimensiunea medie de 54 nm. Spectrul FTIR a evidențiat faptul că biomoleculele din extract au acționat ca agent reducător. Activitatea antibacteriană a nanoparticulelor a fost evaluată asupra bacteriilor Gram pozitive (Staphyllococcus aureus) și Gram negative (Escherichia coli, Pseudomonas aeruginosa și Klebsiella pneumoniae), iar cea mai mare activitate s-a înregistrat pentru doza de 1 mg/mL SNP asupra P. aeruginosa (17,63 mm). De asemenea, au prezentat o activitate antioxidantă pronunțată în testul DPPH. Sinteza mediată de Ulmus a nanoparticulelor de argint este ecologică, non-toxică și rentabilă, cu efect antibacterian și antioxidant, având potențiale aplicații biomedicale.

Ginger spent is the byproduct of spice industries that remove the essential oils of ginger (Zingiber officinale) for food industry and medicinal purposes. Ginger is a well known spice used often for seasoning in Indian cuisine. The de-oiled ginger has no specific use mostly goes to waste. Hence, we utilized this industrial waste product in the efficient synthesis of silver nanoparticles with the aid of UV irradiation from a solution of 1mM silver nitrate and spent extract in the ratio 9:1. Immediate colour change from pale yellow to dark brown was noted indicating the rapid synthesis of silver nanoparticles. These nanoparticles were centrifuged, dried and well characterized. UV Vis Spectroscopy, XRD analysis, Zeta potential and SEM analysis was carried out. It was commendable that the size of the nanoparticles fell well within the upper limit of 100nm. Agar well diffusion method was used to screen the antimicrobial activity of the well characterized silver nanoparticles. They were tested against seven pathogenic strains of three gram negative bacteria (Escherichia coli, Klebsiella pneumonia and Pseudomonas aeruginosa) three gram positive bacteria(Bacillus subtilis, Staphylococcus aureus and Streptococcus faecalis) and a fungus (Candida albicans). It was seen that the zone of inhibition(ZOI) in well plate method increased on increasing the concentration of silver nanoparticles. Further studies could lead to the application of these silver nanoparticles in medicine.
