“…Both organic and inorganic coating types have been applied using a broad variety of the surface modification techniques to bypass this challenge. While there are few reports dealing with the application of organic materials, such as GO [26] and chitosan [27], to coat NiTi, a numerous number of attempts have been made to improve the in vitro biocompatibility of NiTi by the deposition of inorganic coatings, such as CaP family [28], ZrO2 [29], and Al2O3 [30]. Recently, the synergistic combination of organic/inorganic coating materials in the form of either single layer (composite coating) or multilayer systems have garnered great attention [22,31].…”

“…Guo et al [175] reported that the preparation of graphene oxide coating on the NiTi SMAs benefited to the corrosion resistance, inhibiting the release of Ni ions, as well as the facilitation of the adhesion, growth, and proliferation of osteoblasts. Similarly, they prepared a bioactive dicalcium phosphate dihydrate (DCPD) coating on the LPBF-NiTi alloys via electrodeposition to improve the corrosion resistance and biocompatibility of the LPBF-NiTi [176]. The DCPD coating offered a good interface and microenvironment for the growth and adhesion of osteoblasts by in vitro cell experiments.…”

NiTi alloys have drawn significant attention in biomedical and aerospace fields due to their unique shape memory effect (SME), superelasticity (SE), damping characteristics, high corrosion resistance, and good biocompatibility. Because of the unsatisfying processabilities and manufacturing requirements of complex NiTi components, additive manufacturing technology, especially laser powder bed fusion (LPBF), is appropriate for fabricating NiTi products. This paper comprehensively summarizes recent research on the NiTi alloys fabricated by LPBF, including printability, microstructural characteristics, phase transformation behaviors, lattice structures, and applications. Process parameters and microstructural features mainly influence the printability of LPBF-processed NiTi alloys. The phase transformation behaviors between austenite and martensite phases, phase transformation temperatures, and an overview of the influencing factors are summarized in this paper. This paper provides a comprehensive review of the mechanical properties with unique strain-stress responses are also explained, which comprise tensile mechanical properties, thermomechanical properties (e.g., critical stress to induce martensite transformation, thermo-recoverable strain, and superelasticity strain), damping properties and hardness. Moreover, several common structures (e.g., a negative Poisson’s ratio structure and a diamond-like structure) are considered, and the corresponding studies are summarized. It illustrates the various fields of application, including biological scaffolds, shock absorbers, and driving devices. In the end, the paper concludes with the main achievements from the recent studies and puts forward the limitations and development tendencies in the future.

“…In nature, the process of living organisms producing tough coatings to provide exoskeletal protection and support for soft tissue, which is termed mineralization, plays key roles in the survival of biosystems ( 26 ). Inspired by this natural phenomenon, various elegant biomimetic systems have been fabricated for drug delivery, biochemical separations, biomedical implants, and others ( 27 , 28 ). Here, we report an electrostatic interaction–mediated biointerface mineralization that forms an ultraresistant and self-removable coating on bacterial surface to tackle these difficulties (Fig.…”

Despite the fact that oral microecologics are effective in modulating the gut microbiome, they always suffer from multiple insults during the journey from manufacture to arrival at the intestine. Inspired by the protective mechanism of mineralization, we describe a cytocompatible approach of biointerface mineralization that can generate an ultraresistant and self-removable coating on bacterial surface to solve these challenges. Mineral coating endows bacteria with robust resistances against manufacture-associated oxygen exposure, ultraviolet irradiation, and 75% ethanol. Following oral ingestion, the coating is able to actively neutralize gastric acid and release encapsulated bacteria through spontaneous yet rapid double-decomposition reaction. In addition to acid neutralization, the generated calcium ions can trigger micellar aggregation of bile acid, enabling dual exemptions from the insults of gastric acid and bile acid to achieve uncompromised bacterial viability. Further supported by the therapeutic efficacy of coated bacteria toward colitis mice, biointerface mineralization provides a versatile platform for developing next-generation living oral biotherapeutics.
