“…The marine sponge Acanthella elongate has been used for the synthesis of silver nanoparticles, which was clearly confirmed by UV-visible spectrum, TEM analysis, FT-IR and X-ray diffraction. 46 The red algae Gelidium corneum extract acted as a reducing agent in the synthesis of silver nano samples. The formed nanoparticles showed potent anti-biofilm efficacy.…”

Background: Soft corals have been endorsed as a plentiful source of bioactive compounds with promising anti-inflammatory activities; therefore, exploring their potential as source of anti-inflammatory metabolites has stimulated a growing research interest. Purpose: To investigate the anti-inflammatory potential of the soft coral, Nephthea sp., in its bulk and silver nanostructure. Metabolomics analysis of Nephthea sp., followed by molecular docking studies, was also conducted in order to explore and predict the secondary metabolites that might provide its inhibitory actions on inflammation. Materials and Methods: The petroleum ether and ethyl acetate fractions were used to synthesize silver nanoparticles. The prepared silver nanoparticles were characterized through UV-vis spectrophotometric, transmission electron microscopy (TEM) and Fourier-transform infrared spectroscopy (FTIR) analyses. Testing for the anti-inflammatory activity was performed against COX-1 and COX-2. Furthermore, liquid chromatography-mass spectrometry (LC-MS) based metabolomics analysis and molecular docking were also applied. Results: A variety of secondary metabolites were identified, among them, sesquiterpenes were found to prevail. The petroleum ether and acetone fractions of Nephthea sp. showed the highest COX-2 inhibitory activities, possibly attributable to their substantial contents of terpenoids. Additionally, the green synthesized silver nanoparticles of both the petroleum ether and ethyl acetate fractions of Nephthea sp. demonstrated higher anti-COX-2 properties. Conclusion: The obtained results showed the effectiveness of non-targeted metabolomics technique in metabolic profiling of Nephthea sp., helping the search for new bioactive metabolites in future chemical studies on this soft coral. The interesting anti-inflammatory potential of the tested extracts and their nanoparticles could also be relevant to the development of new, effective anti-inflammatory agents.

The synthesis of nanoparticles can be accomplished by physical, chemical and biological strategies. Since this has become an expanding area of research in the field of medical sciences and Technology, owing to its potential applications, the need for eco-friendly, non-toxic and economical methods of synthesis have arisen. Biosynthesis of nanoparticles have become the main field of research as it is time efficient, cost effective, less toxic and has abundant resource. This review emphasizes on the biosynthesis of gold (Au) and silver nanoparticles (AgNPs) using marine sources with special reference to algae, their characterisation and its applications. The characterisation of metal nanoparticles is an essential step and can be carried out by various instruments. The various pharmacological, electrical, pest management, parasitology and medical applications of these marine source induced synthesis of nanoparticles have also been portrayed in this review.Â

“…They are used for the treatment of psoriasis (Pietschmann et al, 2004), as anti foulant (Pereira et al, 2002;Riberio et al, 2012), in cosmetics (Swatschek et al, 2002), for marine environmental bioremediation in integrated aquaculture practices (Milanese et al, 2003), bioremediation in polluted sea water (Stabili et al, 2006), to clear large volume of water of organic and bacterial loads in polluted sites (Ledda et al, 2014) as their pumping activity might play an important role in water purification. They are used in the biosynthesis of silver nanoparticles (Inbakandan et al, 2012) as silver nanoparticles are being investigated as tools for novel cancer therapeutics (Ong et al, 2013). The sponges serve as pollution bio indicators (Caraballo 1996;Devoogd 2008;Muricy, 1989;KirubaSankar et al, 2016).…”
