摘要：

The biosynthesis of silver nanoparticles has been successfully conducted using Plectonema boryanum UTEX 485, a filamentous cyanobacterium, reacted with aqueous AgNO3 solutions (similar to 560 mg/L Ag) at 25-100 degrees C for up to 28 days. The interaction of cyanobacteria with aqueous AgNO3 promoted the precipitation of spherical silver nanoparticles and octahedral (111) silver platelets (of up to 200 nm) in solutions. The mechanisms of silver nanoparticles via cyanobacteria could involve metabolic processes from the utilization of nitrate at 25 degrees C and also organics released from the dead cyanobacteria at 25-100 degrees C.
