“…A comparable result was also reported for green alga Spirogyra insignis, which also produced spherical nanoparticles with a mean particle size of 30 nm [96], while macroalga Padina tetrastromatica was found to produce crystalline spherical nanoparticles ranging in size from 5 to 35 nm [97]. Ag nanoparticles synthesized by seaweeds have also been found to have antifungal [86,108], antibacterial [109][110][111][112][113], and anticancer properties [114]. On another front, Ramkumar Vijayan et al have used an aqueous solution containing an extract taken from Turbinaria conoides to biosynthesize both Ag and Au nanoparticles.…”

Today there is a growing need to develop reliable, sustainable, and ecofriendly protocols for manufacturing a wide range of metal and metal oxide nanoparticles. The biogenic synthesis of nanoparticles via nanobiotechnology based techniques has the potential to deliver clean manufacturing technologies. These new clean technologies can significantly reduce environmental contamination and decease the hazards to human health resulting from the use of toxic chemicals and solvents currently used in conventional industrial fabrication processes. The largely unexplored marine environment that covers approximately 70% of the earth's surface is home to many naturally occurring and renewable marine plants. The present review summarizes current research into the biogenic synthesis of metal and metal oxide nanoparticles via marine algae (commonly known as seaweeds) and seagrasses. Both groups of marine plants contain a wide variety of biologically active compounds and secondary metabolites that enables these plants to act as biological factories for the manufacture of metal and metal oxide nanoparticles.

“…Nanomaterials exhibit unique, superior, and essential properties and have attracted much attention for their distinct characteristics that are not displayed in conventional macroscopic materials. Their uniqueness arises specifically due to their higher surface to volume ratio [5,6]. They represent the involvement of controlling and manipulating matter at their atomic scale in the development of novel devices that can be used in various physical, biological, biomedical, and pharmaceutical applications [7].…”

Background: Marine algae used as a food source for ocean life and range in color from red to green to brown grow along rocky shorelines around the world. The synthesis of silver nanoparticles by marine alga Padina sp. and its characterization were fulfilled by using UV-visible spectrophotometer, Fourier transform infrared spectroscopy, scanning electron microscopy and field emission scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Results: UV-visible absorption spectrum revealed that the formation of Ag nanoparticles was increased by the addition of marine algae and the spectral peak observed between a wavelength of~420 nm and 445 nm. In addition, SEM and FESEM images examined the surface morphology and the size of the synthesized NPs was relatively uniform in size~25-60 nm. Energy-dispersive X-ray spectroscopy analysis confirmed the purity of Ag NPs with atomic percentage of 48.34% Ag. The synthesized Ag NPs showed highly potent antibacterial activity. The Staphylococcus aureus and Pseudomonas aeruginosa were found to be more susceptible to silver nanoparticles by forming 15.17 ± 0.58 mm and 13.33 ± 0.76 mm of diameter of the inhibition zone, respectively. Conclusions: The study suggested that marine alga Padina sp. could be an alternative source for the production of Ag nanoparticles and are efficient antimicrobial compounds against both gram-negative and gram-positive bacteria which can be a promising material against infectious bacteria.

BackgroundThe study on newer antimicrobial agent from metal based nano materials has augmented in recent years for the management of multidrug resistance microorganisms. In our present investigation, we synthesized silver nanoparticles (AgNP’s) from red algae, Gracilaria crassa as beginning material which effectively condensed the silver ions to silver nanoparticles with less price tag and no risk.MethodsSilver nanoparticles were prepared by simple reaction of 1 mM AgNO3 with G. crassa extracts at room temperature. The fabricated AgNP’s were subjected for characterization and screened against various microorganisms for antibacterial activity.ResultsUV–Vis spectroscopy (200–800 nm), XRD, FESEM and EDAX, were performed for AgNP’s. UV–Vis spectroscopy demonstrated the absorption edge at 443 nm and EDAX pattern is purely due to the particle size and face centered cubic (fcc) symmetry of nanoparticles. Average size lays at 122.7 nm and zeta potential was found to be −34.9 mV. The antibacterial outcome of synthesized AgNP’s (at the dose of 20 and 40 µg/ml) was evaluated against Escherichia coli, Proteus mirabilis, Bacillus subtilis and Pseudomonas aeruginosa. The mechanism of synthesized AgNP’s bactericidal bustle is discussed in terms of interaction with the cell membrane of bacteria. The activity was found to be sky-scraping in a dose dependent manner.ConclusionThus, environmental friendly, cost effective, non hazardous stable nanoparticles were prepared by green synthesis using red algae, G. crassa. Synthesized G. crassa AgNP’s were in acceptable size and shape. Further, it elicits better bactericidal activity against microorganism. This will assure the out put of superior antibacterial formulation for near future.Graphical Abstract
