Issledovano vzaimodeistvie nanochastits poroshka ferrita kobal'ta, poluchennogo metodom mekhanokhimicheskogo sinteza, i molekul DNK. Pokazano, chto nanochastitsy CoFe₂O₄ effektivno svyazyvayut DNK v vodnoi srede (Tris-HCl), chto privodit k formirovaniyu bionanokompozita. Ustanovleno, chto adsorbtsionnaya emkost' nanochastits СoFe₂O₄ otnositel'no DNK sostavila 5.25 × 10^–3 mol'/m². Proveden analiz desorbtsii DNK s poverkhnosti chastits pri izmenenii rN, ionnoi sily i khimicheskogo sostava sredy. Bionanokompozit DNK–SoFe₂O₄ issledovan metodom IK-Fur'e-spektrometrii. Na osnovanii sovokupnosti poluchennykh dannykh rassmotren mekhanizm vzaimodeistviya polinukleotida s nanochastitsami CoFe₂O₄. Vydvinuto predpolozhenie, chto svyazyvanie osushchestvlyaetsya za schet koordinatsionnykh vzaimodeistvii fosfatnykh grupp sakharofosfatnogo ostova i osnovanii DNK (kislorodnykh atomov timina i guanina) s ionami metalla na poverkhnosti chastits. Analiz IK-spektra pokazal, chto svyazyvanie mozhet privodit' k chastichnoi destabilizatsii struktury DNK, no polinukleotid sokhranyaet V-konformatsiyu.
