“…Only for MND-H, a dip in the absorbance is visible at 1330 cm –1 . This particularity is the focus of recent studies, attributing this phenomenon to a surface conductivity of MND-H in water. ,– Note that for both MND-H and MND-Ox samples, bands located at ca . 3300 and 1620 cm –1 associated, respectively, with the O–H stretching and bending modes may be partially or totally related to the presence of water molecules since infrared measurements were performed under air at ambient temperature.…”

Among the different nanodiamonds, milled nanodiamonds (MNDs) from high-pressure high-temperature synthesis exhibit a crystalline quality close to that of the bulk diamond, making it a serious candidate for quantum or energy-related fields. In this study, MND aqueous suspensions with oxidized (MND-Ox) and hydrogenated (MND-H) surface chemistries were irradiated with gamma-rays. Using optimized nanoparticle-compatible methods, we revealed that MNDs in suspension enhance the production of solvated electrons under irradiation, with a higher yield for MND-H. Also, for the first time, a surface-chemistry-dependent scavenging effect of hydroxyl radicals was highlighted for this type of nanodiamonds.

“…Later, high temperature and pressure techniques were developed for synthesizing NDs . The static-pressure catalyst method can be used for synthesizing NDs at a constant ultrahigh pressure and high temperature with a catalyst . If a catalyst is not used, higher pressures and temperatures are required.…”

“…176 The static-pressure catalyst method can be used for synthesizing NDs at a constant ultrahigh pressure and high temperature with a catalyst. 177 If a catalyst is not used, higher pressures and temperatures are required. Although high-energy ball-milling somewhat compensates for the safety of the high temperature and pressure method, the equipment parts and ball-milling media are easily damaged, and the impurity content of the dispersed particles is too high owing to the high hardness and wear resistance of the diamond material.…”

Advances in nanotechnology and nanomaterials have attracted considerable interest and play key roles in scientific innovations in diverse fields. In particular, increased attention has been focused on carbon-based nanomaterials exhibiting diverse extended structures and unique properties. Among these materials, zero-dimensional structures, including fullerenes, carbon nano-onions, carbon nanodiamonds, and carbon dots, possess excellent bioaffinities and superior fluorescence properties that make these structures suitable for application to environmental and biological sensing, imaging, and therapeutics. This review provides a systematic overview of the classification and structural properties, design principles and preparation methods, and optical properties and sensing applications of zero-dimensional carbon nanomaterials. Recent interesting breakthroughs in the sensitive and selective sensing and imaging of heavy metal pollutants, hazardous substances, and bioactive molecules as well as applications in information encryption, super-resolution and photoacoustic imaging, and phototherapy and nanomedicine delivery are the main focus of this review. Finally, future challenges and prospects of these materials are highlighted and envisaged. This review presents a comprehensive basis and directions for designing, developing, and applying fascinating fluorescent sensors fabricated based on zero-dimensional carbon nanomaterials for specific requirements in numerous research fields.
