I wish to study dye degradation using these nanoparticles but I am unable to find adequate research papers on biosynthesis of iron-selenide nanoparticles.
Adarsh Shetty My view is that the synthesis of FeSex nanoparticles would be analogous to that of FeSx. My first thought would be to pass H2Se gas into a dilute Fe2+ containing solution (e.g. the sulfate or chloride). However, H2Se is exceedingly toxic and I wonder if you have the appropriate laboratory to handle such a material. In nature iron sulfate is reduced by appropriate bacteria to FeS and ultimately sulfur. This is the nearest I can think of a biosynthetic method. See attached for ideas.
You could also look at: 'In vitro biosynthesis of iron selenide nanoparticles for imageable drug delivery platform' Ruth Stephanie, Bo Bae Kim, Ping Xu, Yoojin Choi, Chan Yeong Park, Tae Jung Park https://doi.org/10.1016/j.inoche.2022.109973
Adarsh, I would add to Alan's comments that Se is at ow concentrations in most plants grown in typical environments, Paul
Paul Milham We note, though, that Se isn’t in the elemental form in plants. “Selenium primarily accumulates in plants in the form of seleno amino acids and selenoproteins and also as various Se-containing compounds” (copy and paste). Take a look at the attached.
