biosynthesis of silver nanopartilces by living source is the topical research. it is not the matter of fungi or algae or bacteria, it is all depends on the capping or reducing agent which triggers the reduction of silver precursors to nanosilver. literature says that the unique physio-chemical properties also varies according to the capping or reducing agent.
i m using marine sponges as living source and synthesizing silver nanoparticles for marine biofouling control or antifouling applications.
Ideal for capital veturists!
Thank u so much for the info.

Hope the given link and the article will give an idea about the intracellular or extracellular biosynthesis of nanoparticles..

In my previous research i found that one marine fungi didnt produce extra cellular fungi but when the filtrate was subjected to sonication, it gave promising results.
whereas few soil- derived fungi produced Ag nano particles extracellularly.
I feel that the exact mechanism and process remains skeptical
