Biological fouling has caused a lot of concern in marine industries due to the attachment of microorganisms including bacteria, algae, and diatoms on a marine surface to create a biofilm. Biofouling causes negative impacts on the marine industry such as an increase in weights of hulls, low speed, and high fuel consumption. In the recent past, nanoparticles have attracted a lot of attention in the fields of material science, chemistry, and biology owing to their rare biological properties. Silver nanoparticles (AgNPs) have been long known for its strong toxicity against a wide range of microorganisms. Herein, we synthesized the AgNPs via a green synthesis approach known for its benefits such as one-pot, inexpensive, and eco-friendly; by using Illicium verum (IV) extract as a demoting and sustaining agent. Further, characterization tests of obtained AgNPs-IV were investigated including Ultraviolet-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Atomic force microscopy (AFM). The UV-Vis result confirmed the AgNPs-IV formation with its surface Plasmon resonance peak. FTIR was tested to investigate the bio-functional groups liable for the AgNPs-IV synthesis. XRD peaks also meet with the standard of AgNPs (JCPDS: 41-1402). SEM, TEM, and AFM analysis of AgNPs-IV showed the hexagonal structure with 14.56 nm mean size. The cell growth of diatom on 5 th day with blank sample suspension was 2.308 (Cell 10 5 number/mL), while for AgNPs-IV sample suspension was 0.19 (Cell 10 5 number/mL). The green synthesized AgNPs-IV showed excellent antidiatom activity against Paeodactylum Tricornutum (P. Tricornutum) marine diatom.

The current study reports the green synthesis of silver nanoparticles (AgNPs) using Capparis spinosa leaf extract acting as a capping and reducing agent. The characterization of AgNPs was confirmed using ultraviolet-visible spectrophotometry (UV-Visible), fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM). The plant extract used reduces Ag+ into AgNPs within a few minutes as indicated by the changed color, from yellow to reddish-brown. The UV-vis spectrum of AgNPs appeared a characteristic surface plasmon resonance peak at 400-450 nm. FTIR spectroscopy confirmed the role of plant extract as a reducing and capping agent of silver ions. The spectra of FTIR revealed a broad transmission peaks from 3412 to 617 cm-1. An EDX analysis signal at 3 keV and weight 65.38% showed the peak to be in the silver region, a fact which was confirmed by the presence of elemental silver. Under TEM, the nanoparticles were seen to be spherical, with an average particle size of 13 nm. AgNPs showed antibacterial activity against S.epidermidis, S. aureus, MRSA and E. coli. The inhibition zones for S.epidermidis and S. aureus were 8 to 10 mm, while MRSA is 7 to 10 mm. The inhibition zone of E. coli was higher at 10 to 13 mm.

Green synthesis of silver nanoparticles (AgNPs) using plant extracts has emerged as a viable environment-friendly method. The aim of the study was to biosynthesize AgNPs using cauliflower (Brassica oleracea var. botrytis) waste extract and further test their potential applications in photocatalytic degradation of methylene blue (MB) dye and Hg 2+ biosensing. Optimum extract concentration, AgNO 3 concentration, pH and temperature required for biosynthesis of stable AgNPs were determined by UV-visible spectroscopy. FT-IR, XRD, SEM, TEM, SAED, XPS and BET analysis were performed for characterizing AgNPs. MB dye degradation using AgNPs was determined by analyzing the intensity of dye absorption maxima at 664 nm. Specificity and sensitivity of biosynthesized AgNPs for Hg 2+ ions were studied for assessing their biosensing abilities. Optimum conditions needed for biosynthesis of stable AgNPs were observed to be 3 ml extract, 0.5 mM AgNO 3 , pH 8.5 and microwave-assisted heating at 600 W for 5 min. FT-IR analysis showed that the extract contained necessary functional groups that facilitated biosynthesis of AgNPs. XRD, SEM, TEM, SAED, XPS results confirmed the formation of AgNPs. BET analysis showed that AgNPs had an average size of 35.08 nm and surface area of 19.22 m 2 /g. Maximum MB dye degradation percentage of 97.57% was obtained at 150 min without any significant silver leaching thereby, signifying notable photocatalytic property of AgNPs. Biosensing studies showed that AgNPs were specifically able to detect up to 0.1 mg/l Hg 2+ ions. In summary, cauliflower waste served as a useful source of reducing agents for biosynthesizing AgNPs with promising environmental applications.
