Кафедра "Бiотехнологiя, біофізика та аналiтична хiмiя" була створена у 1998 році на базі кафедри "Аналітична хімія", яка у 1940 році була виділена з кафедри хімії в самостійну кафедру. Ініціатива створення кафедри належить доктору технічних наук, професору Миколі Федосовичу Клещеву.

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут". Кафедра провадить освітню, методичну та наукову діяльність у галузі знань "Хімічна та біоінженерія". Крім теоретичних основ біотехнології, велику увагу було приділяється контролю якості і сертифікації біотехнологічної продукції.

У складі науково-педагогічного колективу кафедри працюють: 2 доктора наук: 1 – технічних, 1 – фармацевтичних; 8 кандидатів наук: 3 – біологічних, 5 – технічних; 2 співробітника мають звання професора, 6 – доцента.

    "Quality by design" in liposomal drugs creation
    (Національна академія наук України, 2020) Krasnopolsky, Yu. M.; Pylypenko, D. M.
    Nanobiotechnological preparations creation is one of the promising areas of modern pharmacy, since it allows creating products of a qualitatively new level. The procedure development, based on an understanding of the product characteristics and the technological process, confirmed by reliable scientific data. The article is devoted to the pharmaceutical development of liposomal drugs. On the basis of our own experience in the development of liposomal medicinal forms, as well as on the basis of literature data, the main components in their composition were detected and these components impact on the quality indicators of liposomes were studied. Individual lipids function in nanoparticle membrane and their interaction, which determines the stability both in the technological process and upon storage of the product, were considered. The advantages and disadvantages of cholesterol incorporation into liposomes with hydrophilic and hydrophobic active pharmaceutical ingredients were described. Cryoprotectors and buffer systems role in ensuring nanopreparation stability is discussed.

    The study of liophilization parameters in the liposomal irinotecan development
    (Національний фармацевтичний університет, 2017) Stadnichenko, O. V.; Krasnopolsky, Yu. M.; Yarnykh, T. G.
    The creation of the liposomal irinotecan is one of the main ways to reduce toxicity and increase the effectiveness of chemotherapy. Lyophilization makes it possible to obtain a product with a guaranteed stability of the size and encapsulation efficiency. Aim. To optimize the content of the cryoprotector in the liposomal irinotecan, and develop lyophilization parameters to produce liposomes with the maximum encapsulation of irinotecan in them, alongside while maintaining the nanosize. Materials and methods. Egg phosphatidylcholine from Lipoid (Germany) was used for preparation of liposomes. Lyophilization was carried out in a Quarco device (PR China). The encapsulation degree was determined on a Shimadzu LC-20 instrument (Japan) by HPLC method developed earlier. Results and discussion. The optimal content of the cryoprotector – trehalose dihydrate has been studied. It has been found that the optimal content of trehalose dihydrate is 8 % (w/w). The modes of the product lyophilization have been studied. The secondary drying temperature in the range of 10-20 °C has been determined. At the secondary drying temperature of 10 °C the residual moisture content was 5-8 %, which was beyond the target range. At 20 °C the water content in the lyophilizate was 0.5-0.8 %, the loss of encapsulation was up to 20 %. The mode of drying at 15 °C was optimal, while the residual water content in the lyophilizate was 1.5-2.8 %, the loss of encapsulation was 13 %, the size of the liposomes after lyophilization and rehydration did not change significantly compared to the initial one. Сonclusions. As a result of the studies, liposomes with irinotecan have been obtained. The content of trehalose dihydrate as a cryoprotector in the range of 4-10 % has been studied. It has been shown that the optimum content of trehalose dihydrate is 8 % (w/w); moreover, the encapsulation decrease in lyophilization is 13 %. The modes of the liposomal irinotecan lyophilization have been studied at the final drying temperature of 10, 15 and 20 °C. It has been found that the optimum final drying temperature is 15 °C.
