“…Starting from the low wavelengths, the peaks in the range 530-600 cm -1 (Figure S3) can be attributed to the Ti-O stretching bond and they are characteristic of the BaTiO3 compound. 40 Shifting to higher wavelengths, the peak at 1450 cm -1 that can be seen in spectrum i ) of plain BTNPs can be attributed to an impurity of BaCO 3 as it has been reported elsewhere. 40 The peaks between 1000-1100 cm -1 (spectrum ii )) are attributed to the C-O-C and C-O-H stretching 41 vibration of the aliphatic chain of poly(ethylene glycol) (PEG), while the peaks in the range 1600-1670 and 1300-1460 cm -1 (spectrum iii )) can be attributed to the Amide I (C=O stretching) 42 and Amide III 40 vibrations of the attached anti-transferrin antibody.…”

The peaks at 2280-2400 and 2850-3000 cm -1 (spectra ii ) and iii )) are attributed to the C-H stretching bond of the DSPE-PEG while the peak at 3320 cm -1 (spectrum iii )) can be attributed both to the O-H stretching vibration of the DSPE-PEG/TfR antibody as well as to the Amide A (N-H stretching) 43 of the TfR antibody.…”

“…Из химически чистых (reagent) реактивов были получены наночастицы BTО в тетрагональной и кубической фазах с формой близкой к сферической методом пероксидного синтеза [10][11][12]. Стабилизация наночастиц достигалась обогащением их поверхности гидроксильными группами −OH − путем кипячения (423 K) в 30% растворе H 2 O 2 в течение 3 h. Полученные гидроксилированные наночастицы дополнительно модифицировались молекулами олеата натрия C 17 H 33 COONa (с гидрофобной (C 17 H 33 ) и гидрофильной (COONa) частями) в процессе интенсивного перемешивания при температуре 358 K в течение 4 h в 0.5% водном растворе согласно [11,12]. Гомогенность коллоидных систем ВТO, используемых при осаждении пленки Ленгмюра-Блоджетт (ЛБ), повышалась в центрифуге MiniSpin plus, Eppendorf с ускорением 14 000g.…”

“…9). При комнатной температуре обнаружены рефлексы тетрагональной (сегнетоэлектрической) (C 1 v ) фазы, а также метастабильной кубической фазы (O 1 h ), как остаточной после пероксидного синтеза [12]. Результаты рентгенофазового анализа согласуются с представленными выше данными электронографического анализа (рис.…”
