Abstract
The negative Comment (1) on our two papers (2, 3) is puzzling and unfortunate, given that Dr. Panich, in his recent review, (4) has actually agreed with us on central aspects of NMR of detonation nanodiamond, and of nanodiamond structure. In the following, we will highlight the agreement on several important facts but also refute some of the misleading specific claims made in the Comment. To properly support our statements, we will provide spectral evidence and specific quotes (several of them from Dr. Panich himself (4)) that confirm our conclusion that the fraction of C═C carbons in pristine, properly purified detonation nanodiamond is ≤2%.
