“…For this purpose, Badeau et al [ 138 ] employed a logic-based peptide hydrogel as a miniature computer system taking inputs from the surrounding microenvironment to decide when to release therapeutic agents for drug delivery. Research devoted to smart biomaterials in biomedical engineering is widely published, and its development is comprehensively summarized in recent works [ 139 , 140 , 141 ].…”

The goal of this review is to map the current state of biodegradable materials that are used in tissue engineering for a variety of applications. At the beginning, the paper briefly identifies typical clinical indications in orthopedics for the use of biodegradable implants. Subsequently, the most frequent groups of biodegradable materials are identified, classified, and analyzed. To this end, a bibliometric analysis was applied to evaluate the evolution of the scientific literature in selected topics of the subject. The special focus of this study is on polymeric biodegradable materials that have been widely used for tissue engineering and regenerative medicine. Moreover, to outline current research trends and future research directions in this area, selected smart biodegradable materials are characterized, categorized, and discussed. Finally, pertinent conclusions regarding the applicability of biodegradable materials are drawn and recommendations for future research are suggested to drive this line of research forward.

“…In order to improve corrosion resistance and biocompatibility, the surface of NiTi shape memory alloys is modified by applying protective multifunctional ceramics, polymers or composites layers [ 1 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. However, the best binding of the metallic implant surface with the bone tissue is ensured by covering its surface with a coating composed of calcium phosphates (CaPs).…”

To functionalize and improve the biocompatibility of the surface of a medical implant made of NiTi shape memory alloy and used in practice, a clamp, multifunctional layers composed of amorphous TiO2 interlayer, and a hydroxyapatite coating were produced. Electrophoresis, as an efficient method of surface modification, resulted in the formation of a uniform coating under a voltage of 60 V and deposition time of 30 s over the entire volume of the implant. The applied heat treatment (800 °C/2 h) let toa dense, crack-free, well-adhered HAp coating with a thickness of ca. 1.5 μm. and a high crack resistance to deformation associated with the induction of the shape memory effect in the in the deformation range similar to the real implant work after implantation. Moreover, the obtained coating featured a hydrophilic (CA = 59.4 ± 0.3°) and high biocompatibility.

“…With the rapid development of medical materials, bioceramic materials specifically zirconia due to their unique properties, including favorable mechanical properties, excellent chemical inertness, exceptional abrasion resistance and biocompatible properties are gradually replacing conventional polymers and metals in the manufacture of dental implants [1][2][3][4][5][6]. Numerous studies have demonstrated that zirconia ceramics are ideal for dental implants due to their ability to osseointegrate as a promising material [7,8].…”

The continuous need for high-performance implants that provide significant biological properties has led to extensive research into the topographic patterns of bioceramics in recent years. Their excellent aesthetics, biocompatibility, low plaque affinity, and ability to reproduce a natural-looking appearance have contributed to their success in dentistry. 3 mol% Yttria-stabilized zirconia (3YSZ) is gaining popularity as a material for dental implants due to its excellent mechanical properties and minimal degradation when exposed to body temperature. However, such materials show limited biological and antibacterial performance for dental applications. The purpose of this work was to develop microtopographies on the surface of 3YSZ ceramic by laser ablation technique, in order to improve its biological response and antibacterial behaviors. Two types of microtextures, including micro-grooves and micro-channels geometries were fabricated onto the zirconia ceramics using the laser ablation technique. The effects of different microtextures on the wettability, biological and antibacterial behaviors of 3YSZ ceramics were studied. The results indicate that all of the microstructure patterns are capable of improving the performance of 3YSZ. Wettability is a decisive factor that determines the antibacterial performance of textured zirconia ceramics. The microtextured surfaces all display hydrophobic behavior, thus yielding an effective improvement of antibacterial performance for 3YSZ ceramics. Cell-surface interactions were assessed for 7 days on both zirconia textured surfaces and a nontextured control with pre-osteoblast MC3T3-E1 cells. The obtained results showed the positive influence of textured zirconia surfaces on cell biological response.
