Abstract
CURRENTLY, there is a growing need to develop environmentally
…. benign nanoparticle synthesis process that does not use toxic
chemicals in the synthesis protocols. Synthesis of nanomaterials by
biological approach is innovative, cheaper and environmentally
friendly. In this regard, the present study focused on the synthesis of
silver nanoparticles from the microalga Isochrysis galbana. The silver
nanoparticle produced by marine microalga Isochrysis galbana when
incubated with silver nitrate solution at the same culture condition for
24 h and was detected by UV-Vis spectrophotometer, Energy
dispersive X-ray (EDX-ray) and Transmission electron microscope.
The synthesized silver nitrate nanoparticles from the marine microalga
Isochrysis galbana showed the pronounced antibacterial activity
against the tested human pathogens Escherichia coli and Proteus
vulgaris. The above eco-friendly synthesis procedure of silver nitrate
nanoparticles could be easily scaled up in future for the industrial and
therapeutic needs.
