“…In addition, IR features are also observed in the 2800-2900 cm −1 region, assigned to the stretching vibration of CH 2 groups from the PEI backbone. Finally, it is important to note that the intensity of the NH vibration at 1560 cm −1 , compared to the C-C and C=N at 1660 cm −1 , is greater in the latter case, suggesting the presence of more NH groups in the case of the PDA-PEI film [34].…”

“…The polymerization is usually accompanied by a change in the solution color, from colorless to dark brown [26]. In this study, we studied several ways of obtaining PDA films by changing the oxidant agent, atmospheric O 2 or sodium periodate, or by adding a small polymer, PEI, which is known as a good reticulate agent [34,43].…”

“…These results may be surprising when compared with those reported in the literature; for instance, with PDA-PEI-Cl coating, Chien et al have shown 99.99% of killing towards S. aureus and 99.9% towards E. coli, but these results were obtained using an indirect method, ca. CFU numbering on agar plates [34].…”

“…N-halamine based on the co-deposition of PDA and PEI was studied, and it was shown that the antibacterial ability of the coatings increased as the PEI content increased. In addition, the chlorinated co-deposition coatings had significantly increased antibacterial properties compared to the non-chlorinated coatings, with the chlorinated co-deposition coatings inactivating >99.99% of Staphylococcus aureus (S. aureus) and >99.9% of E. coli after contact for less than 10 min with PDA antibacterial materials [27,34].…”

Due to the ability of microorganisms to first adhere to a material surface and then to lead to the formation of a biofilm, it is essential to develop surfaces that have antimicrobial properties. It is well known that N-halamine coatings allow us to prevent or minimize such phenomena. In the present work, various polydopamine (PDA) coatings containing chloramine functions were studied. In fact, three PDA-based films were formed by the simple immersion of a gold substrate in a dopamine solution, either at pH 8 in the presence or not of polyethyleneimine (PEI), or at pH 5 in the presence of periodate as an oxidant. These films were characterized by polarization modulation reflection absorption infrared spectroscopy and X-ray photoelectron spectroscopy analyses, and by scanning electron microscopy observations. The chlorination of these PDA films was performed by their immersion in a sodium hypochlorite aqueous solution, in order to immobilize Cl(+I) into the (co)polymers (PDA or PDA–PEI). Finally, antibacterial assays towards the Gram-negative bacteria Escherichia coli (E. coli) and the Gram-positive bacteria Staphylococcus epidermidis (S. epidermidis) were conducted to compare the bactericidal properties of these three N-halamine coatings. Regardless of the bacteria tested, the PDA coating with the best antibacterial properties is the coating obtained using periodate.

Polydopamine (PDA), as a mussel-inspired material, exhibits numerous favorable performance characteristics, such as a simple preparation process, prominent photothermal transfer efficiency, excellent biocompatibility, outstanding drug binding ability, and strong adhesive properties, showing great potential in the biomedical field. The rapid development of this field in the past few years has engendered substantial progress in PDA antibacterial materials. This review presents recent advances in PDA-based antimicrobial materials, including the preparation methods and antibacterial mechanisms of free-standing PDA materials and PDA-based composite materials. Furthermore, the urgent challenges and future research opportunities for PDA antibacterial materials are discussed.

Bone tissue constitutes 15–20% of human body weight and plays a crucial role in supporting the body, coordinating movement, regulating mineral homeostasis, and hematopoiesis. The maintenance of bone homeostasis relies on a delicate balance between osteoblasts and osteoclasts. Osteoclasts, as the exclusive “bone resorbers” in the human skeletal system, are of paramount significance yet often receive inadequate attention. When osteoclast activity becomes excessive, it frequently leads to various bone metabolic disorders, subsequently resulting in secondary bone injuries, such as fractures. This not only reduces life quality of patients, but also imposes a significant economic burden on society. In response to the pressing need for biomaterials in the treatment of osteoclast dysregulation, there is a surge of research and investigations aimed at osteoclast regulation. Promising progress is achieved in this domain. This review seeks to provide a comprehensive understanding of how to modulate osteoclast activities. It summarizes bioactive substances that influence osteoclasts and elucidates strategies for constructing related biomaterial systems. It offers practical insights and ideas for the development and application of biomaterials and tissue engineering, with the hope of guiding the clinical treatment of osteoclast‐related bone diseases using biomaterials in the future.
