Prospects for the Application of Nanostructured Biocarbon Sorbents in Clonal Micropropagation of Plants

Biocarbon materials are attracting increasing interest from researchers due to their excellent sorption properties and environmental friendliness of their production. Having a developed internal surface, nanostructured biocarbon materials demonstrate record sorption characteristics. One of the promising areas of application of such sorbents is plant biotechnology. Thus, an important problem of clonal micropropagation in vitro is the need to remove metabolites toxic to seedlings, primarily phenolic compounds. Biocarbon sorbents, including nanobiochars, have demonstrated high efficiency in the adsorption of such contaminants, including when introduced into nutrient media for plant-tissue culture. Changing the conditions for the synthesis of biocarbon nanomaterials directly affects their sorption characteristics, which opens up opportunities for the targeted production of optimal sorbents for intensifying and reducing the cost of the clonal micropropagation of plants. At the same time, uncertainty remains regarding the sorption and other properties of such promising materials as biographene and its derivatives when introduced as a component into media for plant-tissue culture. The mechanisms of the adsorption of phenolic compounds by carbon nanomaterials are not fully understood. There are concerns about the risks associated with the exposure of plants to nanoparticles and nanomaterials. All these questions require further research.
