Recently, I read in RG an interesting article by Esther Thomas, Indira Rathore, and J. C. Tarafdar “Bio-Inspired Synthesis of Nitrogen Nanoparticles and Its Application on Pearl Millet (Pennisetum americanum L) cv. HHB 67”. In the conclusion of this article it is said “The present work demonstrated the biosynthesis of the Nitrogen nanoparticles after isolating and identifying an efficient soil fungi Aspergillus tubingenesis TFR 29 (NCBI GenBank accession Number KT 213693). The fungus was found to be very efficient and producing very tiny nanoparticles (1–2 nm size) from NH4NO3 salts. The doses for application to plants were also optimized as 80 ppm. The results suggest that 80 ppm concentration of nano-N application producing by our developed fungus was found to be safer limit and help in significant improvement in root area, length, perimeter, number of tips, root diameter, beneficial enzymes and microbial activities as well as total dry biomass. The nano-nitrogen produced by the fungus can be commercialized by the industry to manufacture nanofertilizer for agricultural use in future.
The bio-synthesized Nitrogen nano-particles produced with the help of fungal protein showed enormous potential. It is very eco-friendly and complete bio-source as well as cheaper technology. It helps in almost three times more nutrient use efficiency and requires much less than chemical fertilizer for equivalent yield.. The yield increase ranges from 23 and 45% of eleven different crops tested so far under both farmers and research field conditions. It helps the plants more secretion of enzymes in the rhizosphere resulted up to 30% more mobilization of native nutrients. It makes plants more active after foliage application.
If they were really successful to synthesize Nitrogen nano-particles with the help of fungal protein, Then this is a big achievement. congratulations to authors..
In general synthesis of Nitrogen nanoparticles is not so easy. But the authors have reported synthesis by Fungi. Great efforts..
Dear Dr. Tarafdar, who is the author of this idea? Who, besides you, has done similar research?
The concept was developed by me. Our group was doing the similar research. Many industry has now come forward to commercialize the technology.
Here is another citation for urea-hydroxyapatite nanoparticles.

I question the use of the term "nitrogen nanoparticles." This is a good marketing concept but I question its use as scientific nomenclature- silicon nanoparticles are obviously composed of elemental silicon. Polystyrene nanoparticles provide the reader with an reasonably unambiguous description of the material. Searching for nitrogen nanoparticles (which are NOT in any way what the description describes) leads to few hits, while urea-hydroxyapatite nanoparticle leads to literature dating back to at least 2010.
Dear Myron Todd Coolbaugh. Yes, I agree that this is a good marketing concept. On the other hand, the title "Nitrogen nanoparticles" is a trivial, similar to "soil organic matter" or "soil carbon". It is clear, that theoretically, these nanoparticles can be as many as there are nitrogen compounds or their complexes with other substances.
I disagree on the triviality of the nomenclature. The author reports what may be a novel method for preparing a previously reported system and appears to be claiming precedence or originality in both discovery and application when in fact a cursory search using previous descriptive nomenclature reveals both urea-hydroxyappetite nanoparticles and thier suggested application as fertilizer both predate the publication in question. Could someone claim to be pioneering the field of "inorganic-organic conglomerates as media for agriculture I'm sure someone would point out that is
I would use a new keyword such as "nitrogen rich nanoparticles" to refer to such materials. This terminology is chemically acceptable and includes the possibility of using various other components than hydroxyapatite and urea that could bediscovered in the future .
Application of biologically synthesized nano-nitrogen improves
plant growth and development, root parameters, enzyme
and microbial activities as well as total biomass of plants. Hence the synthesis nitrogen nanoparticles has immense potential in Agriculture
