What is the difference between nanomaterials and functional nanomaterials?
A functional nanomaterial is a compound that at least presents one dimension (length, height, width) in the nanometer scale and has been post-processed either chemically or physically to provide specific properties, like solubility, wetability, fluroescence, strength, ductility, which the raw material did not exhibit.
A very good and necessary question. At present it is difficult to give a proper definition instantly, but presently and urgently a rough skeletal definition is postulated requiring improvement for final optimization and acceptance.
"A functional nanomaterial is a organized molecular entity with capacity for doing a specified function under a specific set of working environment ".
I think the best and most commonly applicable example of functional nanomaterials are proteins and nucleic acids. They are nano tools per excellance.
There is plenty of scope for rectifying the proposed definition. A very good question for activating our thoughts and defining capacity.
For different application, stability of NPs is essential which is accrued by functionalization of NPs.

To me funtional nanomaterials are those whose surface is modified by other materials, these include core shell particles and patchy particles to be used in specific applications.
Fictionalization of nano-particle means modification in surface characteristic by attaching surface by any other chemical entities so that its delivery or target would be altered to meet the deemand or enhance performance of productss.
"Functional nanomaterials" are nanomaterials that is given a special task (or could be said as functionalized by chemical/physical processes - as quoted by Jan Englert) for a specific application. For example: semiconductor quantum dots are very useful as bioconjugates for cell imaging, labering and sensing. However, they are not bio-compatible. Therefore, they are functionalized through different chemical processes and made biocompatible.
