Abstract:
Tissue engineering is an interdisciplinary field of science that has been developing very intensively over the last dozen or so years. New ways of treating damaged tissues and organs are constantly being sought. A variety of porous structures are currently being investigated to support cell adhesion, differentiation, and proliferation. The selection of an appropriate biomaterial on which a patient\'s new tissue will develop is one of the key issues when designing a modern tissue scaffold and the associated treatment process. Among the numerous groups of biomaterials used to produce three-dimensional structures, hydroxyapatite (HA) deserves special attention. The aim of this paper was to discuss changes in the double electrical layer in hydroxyapatite with an incorporated boron and strontium/electrolyte solution interface. The adsorbents were prepared via dry and wet precipitation and low-temperature nitrogen adsorption and desorption methods. The specific surface area was characterized, and the surface charge density and zeta potential were discussed.
摘要:
组织工程是一个跨学科的科学领域,在过去的十几年里一直在激烈地发展。治疗受损组织和器官的新方法不断被寻求。目前正在研究各种多孔结构来支持细胞粘附,分化,和扩散。在设计现代组织支架和相关治疗过程时,选择合适的生物材料是患者新组织将在其上发展的关键问题之一。在用于生产三维结构的众多生物材料中,羟基磷灰石(HA)值得特别关注。本文的目的是讨论具有硼和锶/电解质溶液界面的羟基磷灰石中双电层的变化。采用干湿沉淀法和低温氮气吸附解吸法制备吸附剂。表征了比表面积,并讨论了表面电荷密度和ζ电位。
