The protein extract of alga and HAuCl4 in a 1 1 ratio in the presence of NaOH was incubated at room temperature for 48 h.
This present investigation deals with a simple, eco-friendly synthesis of gold nanoparticles by the reduction of aqueous AuCl4 into nanoparticles using the extract of marine algae T. conoides.
Alcoholic extract of the algae was prepared as described earlier and the presence of biologically active components including alkaloids, flavonoids, sterols, terpenoids, proteins, saponins, phenols, coumarins, tannins and glycosides was documented using spectrophotometric analysis [ 17].
Recently, we demonstrated that extract of brown algae including Saccharina japonica[ 19, 20], M. myagroides[ 21, 22], Ecklonia stolonifera[ 15], and Sargassum fulvellum[ 39] inhibited the activation of NF-κB signaling pathway through the blockade of proteolytic degradation of IκB-α.
Iron oxide nanoparticles were synthesized from FeCl3 with an aqueous extract of brown alga Sargassum muticum at 25 °C.
Phlorotannins-enriched extract of brown alga of H. grandifolius exhibited cytotoxicity against tumor cell line including Hep-2 and promoting cell death trough apoptosis mechanisms [34].
The extract of the brown algae Fucus vesiculosus (bladderwrack algae) has the greatest number of notifiers (123).
A similar mutagenic evaluation was done on aqueous extract of the green alga Spirogyra neglecta by Thumvijit et al. [ 32] using S. typhimurium strains TA98 and TA100.
In this investigation, we studied the green synthesis of gold nanoparticles using the algae extract of Turbinaria conoides.
In conclusion, the gold nanoparticle was synthesized using the algae extract of T. conoides as this seaweed is an easily available marine source.
