There is a growing demand for bone grafts by various clinical sectors, such as aesthetic procedures, treatment of injuries and dentistry, the use of synthetic materials is shown to be good due to the availability and the reduction of risks that their use brings, among the materials that are used in the clinic can be cited the chitosan matrix composites (CHI) with hydroxyapatite (HA) and carbon nanotubes (CNTs), which uses materials that are already used in the clinic HA and CHI with an innovative material in the sector the CNTs. The aim was to analyze and compare data from the current state of the art of CHI matrix composites with HA and CNTs applied in bone tissue engineering. This study is based on a review of the specialized literature on articles in online scientific journals, with thematic issues related to the properties of the biocomposite on board. The influence of the use on the composite properties generated by the use of CNTs together with the HA in the CHI matrix, for biomedical applications, more specifically in bone tissue engineering, was observed. It was observed that with subtle increases of CNTs in the CH composite Ha composites, the bioactivity, osteoconduction, antibacterial activity, mechanical properties of the composites, changes in the nanotexturas, and a homogeneous distribution of the materials occur, potentiality of its use in more than one application within bone tissue engineering. In the present study it was possible to observe that CHI matrix composites with HA and CNTs present a combination of properties highlighting the potential for application in bone tissue engineering.

Исследованы структурные особенности нанокомпозитов, полученных при лазерном облучении водно-белковых сред с одностенными углеродными нанотрубками (ОУНТ), электродуговым (ОУНТI) и газофазным методами (ОУНТII). С помощью спектроскопии комбинационного рассеяния нанокомпозитов определен нековалентный характер взаимодействия нанотрубок с молекулами белков. Белковая составляющая в нанокомпозитах подверглась необратимой денатурации и может выступать в качестве связующего биосовместимого материала, который является источником аминокислот для биологических тканей при имплантации нанокомпозитов в организм. Образцы, изготовленные из ОУНТI, с меньшим диаметром и длиной имели наиболее однородную структуру. При увеличении концентрации от 0.01 до 0.1 % происходило увеличение среднего размерамикропор от 45 до 85 мкм и пористости образца в общем с 46 до 58 %. При этом доля открытых пор для двух типов концентраций ОУНТI составила 2 % от общего объема композита. В нанокомпозитах на основе ОУНТI показано наличие мезопор. Увеличение концентрации нанотрубок привело к уменьшению удельных значений поверхности и объема пор образца. Исследованные нанокомпозиты могут использоваться в качестве тканеинженерных матриц для восстановления объемных дефектов биологических тканей   REFERENCES Eletskii A. V. Carbon nanotubes.

Bone Damage

Severe bone damage from diseases, including extensive trauma, fractures, and bone tumors, cannot self-heal, while traditional surgical treatment may bring side effects such as infection, inflammation, and pain. As a new biomaterial with controllable mechanical properties and biocompatibility, hydrogel is widely used in bone tissue engineering (BTE) as a scaffold for growth factor transport and cell adhesion. In order to make hydrogel more suitable for the local treatment of bone diseases, hydrogel preparation methods should be combined with synthetic materials with excellent properties and advanced technologies in different fields to better control drug release in time and orientation. It is necessary to establish a complete method to evaluate the hydrogel’s properties and biocompatibility with the human body. Moreover, establishment of standard animal models of bone defects helps in studying the therapeutic effect of hydrogels on bone repair, as well as to evaluate the safety and suitability of hydrogels. Thus, this review aims to systematically summarize current studies of hydrogels in BTE, including the mechanisms for promoting bone synthesis, design, and preparation; characterization and evaluation methods; as well as to explore future applications of hydrogels in BTE.
