The review is devoted to analysis of the use of carbon sorbents for medicinal purposes in China and description of some innovative technologies in this field in Ukraine. The review underlines the presence of common roots of sorption therapy development in these two countries determined by pioneer works of Prof. T.M.S. Chang, created to the concept of artificial cells. High level of works of Chinese scientists on sorption purification of blood and combined extracorporeal methods has been mentioned. At the same time, by author's opinion, two other methods of sorption therapy, namely enterosorption and sorption therapy of wounds and burns, has not been properly developed in China. In the review, there are also described the essential results of Ukrainian scientists in the field of blood purification from protein-bound toxins and other harmful compounds what is important for treatment of many serious human pathologies, and also the important data on the use of oral sorbents and dressings from activated carbon materials, which could be considered as a useful addition to achievements of Chinese scientists in the field of the development and use of sorbents for medicinal purposes.

Separation of high-activity Bi from Ac for targeted alpha therapy is challenging due to the instability of existing sorbents. Surface-modified carbon materials have shown promise for use in inverse Ac/Bi generators. However, previously reported materials with irregular shapes may limit their applications in column separations.

Nanoparticles could improve the bioavailability of active agents of various natures to human, animal, and plant tissues. In this work, we compared two methods on the synthesis of calcium phosphate nanoparticles (CaPs), differed by the synthesis temperature, pH, and concentration of the stabilizing agent, and explored the possibilities of incorporation of a low-molecular-weight peptide analogue enalaprilat, the enzyme superoxide dismutase 1 (SOD1), as well as DNA and dsRNA into these particles, by coprecipitation and sorption. CaPs obtained with and without cooling demonstrated the highest inclusion efficiency for enalaprilat upon coprecipitation: 250 ± 10 μg/mg of CaPs and 340 ± 30 μg/mg of CaPs, respectively.

This study presents a new innovative drug delivery system for ciprofloxacin, which is based on the formation of a zinc-doped carbon dots layer on the surface of a titanium alloy (TiAl4V6). In the study, the effectiveness of the synthesis method of a zinc-doped carbon dots layer was determined. The distribution of the layer of carbon dots on the surface of the titanium alloy was investigated using the FT-IR mapping technique, which confirmed the efficiency of the synthesis.

A serious obstacle to the wide medical use is decay losses of Bi during a conventional synthesis of radiopharmaceuticals. In this work, we aimed to develop a two-column Aс/Bi generator providing the accumulation of Bi separately from the parent Ac via continuous circular separation and decay of intermediate Fr.
