Electrophoretic deposition (EPD) is attracting increasing attention as an effective technique for the processing of biomaterials, specifically bioactive coatings and biomedical nanostructures. The well-known advantages of EPD for the production of a wide range of microstructures and nanostructures as well as unique and complex material combinations are being exploited, starting from well-dispersed suspensions of biomaterials in particulate form (microsized and nanoscale particles, nanotubes, nanoplatelets). EPD of biological entities such as enzymes, bacteria and cells is also being investigated. The review presents a comprehensive summary and discussion of relevant recent work on EPD describing the specific application of the technique in the processing of several biomaterials, focusing on (i) conventional bioactive (inorganic) coatings, e.g. hydroxyapatite or bioactive glass coatings on orthopaedic implants, and (ii) biomedical nanostructures, including biopolymer-ceramic nanocomposites, carbon nanotube coatings, tissue engineering scaffolds, deposition of proteins and other biological entities for sensors and advanced functional coatings. It is the intention to inform the reader on how EPD has become an important tool in advanced biomaterials processing, as a convenient alternative to conventional methods, and to present the potential of the technique to manipulate and control the deposition of a range of nanomaterials of interest in the biomedical and biotechnology fields.
电泳沉积(EPD)作为一种有效的生物材料加工技术,特别是生物活性涂层和生物医学纳米结构,正受到越来越多的关注。人们正在利用 EPD 的诸多优势来生产各种微结构和纳米结构,以及独特而复杂的材料组合,其起始材料是分散良好的生物材料颗粒悬浮液(微纳米颗粒、纳米管、纳米片)。人们还在研究生物实体(如酶、细菌和细胞)的 EPD。本综述全面总结和讨论了 EPD 的相关最新研究工作,描述了该技术在几种生物材料加工中的具体应用,重点介绍了(i)传统生物活性(无机)涂层,如骨科植入物上的羟基磷灰石或生物活性玻璃涂层,和(ii)生物医学纳米结构,包括生物聚合物-陶瓷纳米复合材料、碳纳米管涂层、组织工程支架、蛋白质和其他生物实体的沉积用于传感器和先进功能涂层。本综述旨在让读者了解 EPD 如何成为先进生物材料加工的重要工具,作为传统方法的替代方法,并展示该技术在生物医学和生物技术领域中控制和操纵一系列纳米材料沉积的潜力。
