“…Unfortunately, many previous reports were at the stage of “ proof of concept ”; they did not conform strictly to a specific application. According to the papers we have screened, major flaws in our current reporting on developing antibacterial surfaces for implantable medical devices are ( Table 7 includes some typical examples [ 18 , 272 , 273 , 274 , 275 , 276 , 277 , 278 ]) (1) many reports are lack of comprehensive understanding of the requirements of a specific application or even have no clear indication of use (Cases 2, 3, 7, and 8 in Table 7 ); as a result, it is hard to ensure the effectiveness and safety of such designs because the incidence and pathogens of DAIs are site-specific [ 66 ] and the biocompatibility of biomaterials is referred to specific applications [ 279 ]. (2) Some reports choose testing assays that do not closely relate to the intended use.…”

The uses of implantable medical devices are safer and more common since sterilization methods and techniques were established a century ago; however, device-associated infections (DAIs) are still frequent and becoming a leading complication as the number of medical device implantations keeps increasing. This urges the world to develop instructive prevention and treatment strategies for DAIs, boosting the studies on the design of antibacterial surfaces. Every year, studies associated with DAIs yield thousands of publications, which here are categorized into four groups, i.e., antibacterial surfaces with long-term efficacy, cell-selective capability, tailored responsiveness, and immune-instructive actions. These innovations are promising in advancing the solution to DAIs; whereas most of these are normally quite preliminary “proof of concept” studies lacking exact clinical scopes. To help identify the flaws of our current antibacterial designs, clinical features of DAIs are highlighted. These include unpredictable onset, site-specific incidence, and possibly involving multiple and resistant pathogenic strains. The key point we delivered is antibacterial designs should meet the specific requirements of the primary functions defined by the “intended use” of an implantable medical device. This review intends to help comprehend the complex relationship between the device, pathogens, and the host, and figure out future directions for improving the quality of antibacterial designs and promoting clinical translations.

“…At present, EPD has also been applied for the deposition of other coatings, e.g. graphene oxide (Yuan et al 2022 ), TiO 2 (Gómez et al 2021 ; Yang et al, 2006 ), and etc. In addition to the intermediate pre-coatings, a kind of metal composite coatings is also achieved.…”

With the awakening of environmental awareness, the importance of air quality to human health and the proper functioning of social mechanisms is becoming increasingly prominent. The low cost and high efficiency of catalytic technique makes it a natural choice for achieving deep air purification. Stainless steel alloys have demonstrated their full potential for application in a variety of catalytic fields. The diversity of 3D networks or fibrous structures increases the turbulence within the heterogeneous catalysis, balance the temperature distribution in the reaction bed and, in combination with a highly thermally conductive skeleton, avoid agglomeration and deactivation of the active components; corrosion resistance and thermal stability are adapted to highly endothermic/exothermic or corrosive reaction environments; oxide layers formed by bulk transition metals activated by thermal treatment or etching can significantly alter the physico-chemical properties between the substrate and active species, further improving the stability of stainless steel catalysts; suitable electronic conductivity can be applied to the electrothermal catalysis, which is expected to provide guidance for the reduction of intermittent emission exhausts and the storage of renewable energy. The current applications of stainless steel as catalyst or support in the air purification have covered soot particle capture and combustion, catalytic oxidation of VOCs, SCR, and air sterilization. This paper summarizes several preparation methods and presents the relationships between the preparation process and the activity, and reviews its application and the current status of research in atmospheric environmental management, proposing the advantages and challenges of the stainless steel-based catalysts.

“…[4][5][6] So, the lack of an effective strategy to prevent longterm bacterial infection and meanwhile achieve strong cervical soft tissue integration has fueled the growing interest in surface modification or depositing functional coatings for the Ti/TiO 2 implant. 7 So far, numerous molecules such as chitosan, 8 peptides, 9 inorganic metal elements, 10 and antibiotics 11 have been applied to implant interfaces by physical adsorption or chemical covalent conjugation to fabricate an antibacterial or antimicrobial interface. Silver nanoparticles, alloys, and ions, in particular, have been widely used as promising candidates in the development of new bactericides due to their unique electronic, optical, and chemical properties.…”
