By using proper plant extract one may synthesize nano-particles from the respective salt solutions. But, I think, proper microbial protein may be more useful to get organic mixture of nano-particles.

Hi,

Nano spray drying of diluted solutions. You will get loose aggregates based on nanoparticles.

Hi

Thank you Dr. Mitev ...But is nano spray drying requiers a cpecial equipment?

One of the options: http://www.buchi.com/en/products/spray-drying-and-encapsulation/nano-spray-dryer-b-90-hp

Thanks again Dr. Mitev... I saw these links but they say that the spray drier makes particles with a size about 300 nanometer while nanotechnology deals with a scale between 1 and 100 nanometer.

So how can we deal with them when we need as small as possible particles to get the biological application benefits of them?

Dr. Tarafdar..thanks alot for your answer , but I was asking about synthesizing nanoprticles from the organic solution itself, not to use it to make metal nanoparticles with the aid of the organic compounds. Thank you for your effort to answer my question.

With the help of proper enzymes or microbial protein you will be able to make it.

Dear Dr. Tarafdar ,could you send me the procedure, please?

Please look at some of my publication on the aspect available under research gate.

They are about inorganic nanoparticles not organic which I am asking about....Thank you, I think the suitable way is what Dr. Mitev mentioned ( nano spray drying). Thank you dr. Tarafdar.

Dear Fadwa, your aim is to break down the particles into nano by microbial enzymes. So it is immaterial whether the particles are organic or inorganic only thing you have to choose the correct enzyme combination that needs some research.

Dear Dr. Tarafdar, thanks alot for your help and patience in answering me. But what about if it was a plant extract which means that it contains so many components, so it will be hard to find suitable enzyme mix to make all its components in nano size?!! Because in such extract the biological activity is the yield of the activity of all its components together.

Thats why research is needed with your organic mixture to break with the suitable enzyme combination, I think if you try you will be able to find some microbial protein combination from the fungal ball to break your organic mixture into nano.
