“…Carbon nanoparticles (CNPs) are a promising material for biomedical applications; they have appealing chemical, physical, and optical properties and high biocompatibility and are cheap to synthesize and easy to modify. Modern biosensors, adsorbents, bioimaging agents, and targeted drug delivery systems based on CNPs are being actively developed. , …”

“…Properties of CNPs are largely defined by the processes occurring at the interface between nanoparticles and their environment. Like that, for both nanodiamonds (NDs) and carbon dots (CDs), the structure of surface groups and peculiarities of their interactions with surrounding molecules influence the colloidal stability − of nanoparticles and their adsorption properties − and biocompatibility. − …”

“…For NDs, the depednece of PL on their surface chemistry, 15−20 on the strength of the environments' hydrogen bonds, 15,17,21 and on interactions with biomolecules 11,22−24 allowed us to distinguish the specific type of ND emission:surface photoluminescence, distinct from the well-studied PL of color centers in the diamond core. 25−28 Recently, increasingly more authors believe that the source of surface PL of nanodiamonds is the functionalized sp 2 hybridized carbon on their surfaces. 29−33 For CDs, surface photoluminescence is the main one and is the primary reason for the interest of biomedicine in CDs.…”

Surface Photoluminescence of Oxidized Nanodiamonds: Influence of Environment pH

et al. 2021

Nanoparticles’ environment, in particular pH, can strongly affect their photoluminescence (PL). This can be especially true for the surface PL of nanodiamonds (NDs) known to be dependent on the composition of surface groups. In this paper, the effect of environmental pH in the range from 2 to 12.5 on the surface photoluminescence of oxidized NDs of various syntheses and surface treatments was investigated. For the first time, the varying changes of the NDs’ PL with the pH were shown, having, however, an essential common feature: they were observed in the same pH regions from 2 to 5 and from 9 to 12.5, while in the pH region from 5 to 9, the PL intensity of all samples was almost constant. Obtained dependences of NDs’ ζ-potentials on pH and quantum mechanical modeling showed that all changes of NDs’ PL are due to the (de)protonation of surface groups: carboxyl at pH from 2 to 5 and hydroxyl on sp2-hybridized carbon at pH from 9 to 12.5. The varying response of NDs’ PL to such deprotonation shows the possibility of tuning the surface photoluminescence of NDs for use in industry and biomedicine beyond what is possible by only controlling the nanodiamonds’ surface groups.

This review contains the main research directions, which are directly aimed at converting materials based on rice husks particularly, for their role for medicine and biotechnology. Especially in developing countries, more than 95% of rice husks are produced. Although numerous studies have been conducted on the production of various materials from rice husks, the existing scientific information is still widely scattered in the literature. Therefore, this review article provides extensive information on the work of various researchers, including the Institute of Combustion Problems (Almaty, Kazakhstan), on the production of various materials from rice husks and their physico-chemical characteristics. The main applications of rice husk materials in medicine are discussed. The ways of prospective conversion of rice husks for biotechnological purposes are considered.

Properties and defence applications of carbon nanotubes are discussed in the paper. Carbon nanotubes are important emerging materials, showing diverse unique and interesting properties, such as optical, electronic, magnetic and mechanical properties, at the same time high chemical reactivity as well, due to their quantum confinement effects, more important, these properties are tunable in some extend. Lots of applications such as strength-enhanced structure materials, radar-absorbing structure, armor, body armor, wearable thermoelectric devices, smart textiles, water purification, warfare agent sensors and flat panel display, and so on, can be found using carbon nanotubes.
