“…In living tissue, HYH is usually combined with proteins to control various functions of the tissue. Anodic EPD has been developed for fabrication of HYH films and composites from sodium hyaluronate (HYNa) solutions in water or in a mixed ethanol -water solvent (Grandfield et al 2009;Ma et al 2010a,b). The deposition mechanism of this polysaccharide has been discussed in recent investigations Ma et al 2010a).…”

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.

“…Anodic EPD has been developed for the fabrication of composite films containing HA nanoparticles and CNTs in HYH matrices (Grandfield et al 2009;). It was found that HY 2 species adsorbed on HA and CNTs provided efficient electrosteric stabilization and charging of the HA nanoparticles and CNTs.…”

“…The CNTs suspension was prepared by adding to an aqueous solution of multi-walled carbon nanotubes of commercial origin, Triton X-100 as an ionic surfactant and iodine 99.999% (Aldrich Chemical Company Inc) as a charger [14][15]. The resulting suspension was sonicated for 30 minutes to help CNT uniformly dispersed in the solution.…”

Abstract.A uniform CNTs coating on highly porous nanofibrous and biodegradable PLLA scaffolds, intended for tissue engineering, by the electrophoretic deposition (EPD) technique. The morphologies before and after EPD of CNT coating were investigated by SEM. The mechanical properties were also measured and the EPD mechanism was discussed. The negatively charged CNTs enforced by the electric field moved towards the anode through the gaps of PLLA nanofibers of the scaffolds, where they interwined with PLLA nanofibers and form CNT coating. The nanocomposite scaffolds after CNT coating still remain interconnectivity as high as the control PLLA scaffolds. We finally got a scaffold that aimed to simulate different scale levels for tissue engineering purpose. The different scales from macro-scale (10µm-425µm), subcellular scale structures (0.1-10 µm) to nanostructures (20-100 nm) are favor to control cellular environment and cell-matrix interactions. The CNT coating can greatly improve the compressive modulus of the 3D PLLA scaffolds.

“…[88][89][90] The combination of CNTs with hydroxyapatite and bioactive glass particles to form novel nanostructured inorganic bioactive coatings by using EPD is discussed in the following sections. EPD methods developed recently 91,92 for the synthesis of functionalized single-walled CNTs/polymer composites, which enable also the co-deposition of HA particles, will not be discussed in this review, as they fall in the group of polymer composite films, which are beyond the scope of the present paper.…”
