capping of nanoparticles provide stability and prevents aggregation. Therefore, socio-economically a product must meet the criteria of stability. I hope the information will help you.

thank you

Ya thanks for the response Nabojit Das , but my question is specific towards agriculture, I just want to know whether Researchers working in Agriculture Biotechnology, are capping NPs for application in crops or they are using without capping. All the papers I have gone through, yet none capped NPs for application in Crops, thats why the question came to my mind, whether it is necessary or not.

necessity depends on what you want to explore through your work. If you want to use the nanoparticle as an analog molecule then I don't think capping is necessary but if you want your nanoparticle to be used as commercial product then it must be stable which is provided through capping. Also, most of the nanoparticles without capping precipitates within weeks. So, if you want to do a long term study using nanoparticle from the same lot then it would be difficult to do the experiment.

Hope, I met your query this time.

Thank you

ya, Thank you, I got some info from your ans. But my query is something different; specific towards agricultural appplication. I just want to know whether Researchers working in agriculture are capping NPs or not, whether it is ok without cappping or capping is strictly required, I want to know the practical view, not the theoretical basic concept of capping.

By the way thanks for your response, Can I ask, whether the capped one don't precipitate even in long term use?

Capped nanoparticles can be stable for months. And yes regarding application in agriculture, you should firstly confirm the physiological environment inside the plant or where you nanoparticles are intended to target. Because, nanoparticles without capping tend to aggregate at various ionic strength, pH and physiological environment. This is why capping is also necessary.
