“…Electrochemical techniques offer an undeniable advantage over other techniques for synthesizing metallic HSS, such as a short processing time, and in many cases, biomimetic materials are obtained (Ren et al, 2006;Jiang et al, 2017;Liu et al, 2017;Galvão et al, 2019;Martínez-Cartagena et al, 2021). There are many examples of hard templates for the electrodeposition of threedimensionally ordered metals.…”

The current challenges in developing novel nanotechnological processes have led us to explore new methods for synthesizing nanomaterials whose functionalities rely on their structural complexity. In this respect, nature has always been a source of inspiration for proposing innovative technologies to improve the quality of life. Hierarchical superstructures (HSS) are of great interest because the self-assembly of low-dimensional nanostructures (up to the macroscale) allows the control and optimization of performance by coupling the properties of the individual blocks. Self-assembled surfactant structures are convenient for HSS synthesis because they provide a confined reaction medium which confers excellent control over the size of the building blocks. Furthermore, bicontinuous microemulsions offer a soft three-dimensional template due to their interconnected nature. Similarly, electrodeposition routes offer fast, robust, clean, and reproducible ways to synthesize metallic and multimetallic HSS. The combination of soft-templating and electrodeposition is a powerful tool for controlling the morphology and composition of the material. This work reviews polymeric, ceramic, and metallic hierarchical superstructures synthesized using bicontinuous microemulsions and electrodeposition techniques and compares them with matching natural patterns. The aim is to show how these synthetic routes can be exploited to obtain efficient biomimetic nanomaterials that improve their properties.

“…A. Pawlik et al also obtained a Ch-HAp coating on a Ti substrate using the electrophoretic deposition method and found that the deposition time and voltage affect the morphology of the coating [19]. Tubular structures based on Ti and Ch obtained by the electrochemical single-step process indicated their high potential in application as dental implants [20]. HAp/Ch-based coatings on Ti substrates have also been shown to be suitable for the immobilization of antibiotics and their local release into the biological environment [21].…”

The aim of this work is in situ anodization/anaphoretic deposition of a nano amorphous calcium phosphate (ACP)/chitosan oligosaccharide lactate (ChOL) multifunctional hybrid coating decorated with selenium (Se) on a titanium substrate and in vivo investigation of its immunomodulatory and anti-inflammatory effect. Investigating phenomena at the implant–tissue interface of interest for controlled inflammation and immunomodulation was also the aim of the research. In our earlier research, we designed coatings based on ACP and ChOL on titanium with anticorrosive, antibacterial and biocompatible properties, while in the presented results we show that selenium addition makes this coating an immunomodulator. The immunomodulatory effect of the novel hybrid coating is characterized by the examination of the functional aspects in the tissue around the implant (in vivo): proinflammatory cytokines’ gene expression, M1 (iNOS) and M2 (Arg1) macrophages, fibrous capsule formation (TGF-β) and vascularization (VEGF). The EDS, FTIR and XRD analyses prove the formation of a ACP/ChOL/Se multifunctional hybrid coating on Ti and the presence of Se. A higher M2/M1 macrophage ratio in the ACP/ChOL/Se-coated implants compared to pure titanium implants (a higher level of Arg1 expression) is noted at all time points examined (after 7, 14 and 28 days). Lower inflammation measured by gene expression of proinflammatory cytokines IL-1β and TNF, lower expression of TGF-β in the surrounding tissue and higher IL-6 expression (solely at day 7 post-implantation) is noted in presence of the ACP/ChOL/Se-coated implants.
