Using nanosized drug delivery systems allows to overcome the mechanisms of multidrug resistance of cancer, in this case, chemotherapeutic agents can effectively introduce into cancer cells by endocytosis and accumulate near the nucleus and far from ATP-binding cassette transporters. Creation of boron nitridebased drug delivery nanocarriers with high chemical and oxidative stability is one of the perspective ways. Using chemical vapor deposition spherical boron nitride particles,100–150 nm in diameter (BNNPs), with peculiar petal-like surfaces or smooth surfaces were fabricated. BNNPs were loaded with doxorubicin. Drug loading efficacy of BNNPs-DOX was about 0.095 mg/mg of particles. BNNPs-DOX were relatively stable at neutral pH, whereas DOX is effectively released from the BNNPs at acidic pH (pH 4.5–5.5). Using confocal microscopy, the uptake of BNNPs-DOX by IAR-6-1, KB-3-1, К562 cells and multidrug resistant КВ-8-5 и IS-9 cells was studied. Most of BNNPs-DOX had been co-localized with LysoTracker, indicating that BNNPs-DOX are located in the endosomes/lysosomes after intracellular delivery.</p></abstract><trans-abstract xml:lang="ru"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>boron nitride nanoparticles</kwd><kwd>boron nitride nanocarriers loaded with doxorubicin</kwd><kwd>confocal microscopy</kwd><kwd>endosome/lysosome</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>наночастицы нитрида бора</kwd><kwd>наноконъюгаты частиц нитрида бора с доксорубицином</kwd><kwd>конфокальная микроскопия</kwd><kwd>эндосома/лизосома</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
