Abstract:
This study aimed to create new composite materials based on diatomite—a non-organic
porous compound—through its surface modification with bioactive organic compounds, both synthetic and natural. Chloramphenicol, tetrahydroxymethylglycoluril and betulin were used as modifying substances. Composite materials were obtained by covering the diatomite surface with bioactive
substance compounds as a solution and material dispersion in it. The materials were characterized by
IR spectroscopy, SEM and X-ray photoelectron spectroscopy. For the biocomposites, the hemolytic effect, plasma proteins’ adsorption on the surface and the antibacterial activity of the obtained materials
were studied. Results show that the obtained materials are promising for medicine and agriculture.
