“…125 To achieve the desired properties, layer-by-layer (LBL), core-shell, multi-layers, sandwich-like, and other techniques have been developed to layer different materials in an orderly fashion. [126][127][128] Among these techniques, the PDA coating has garnered more attention as a surface modification due to its essential roles in multilayer structures. [129][130][131] Layer-by-Layer Structure LBL assembly, a highly promising technique, involves the fabrication of thin multilayer coatings through the electrostatic mutual attraction of oppositely charged polyelectrolytes.…”

The various tissue damages are a severe problem to human health. The limited human tissue regenerate ability requires suitable biomaterials to help damage tissue repair and regeneration. Therefore, many researchers devoted themselves to exploring biomaterials suitable for tissue repair and regeneration. Polydopamine (PDA) as a natural and multifunctional material which is inspired by mussel has been widely applied in different biomaterials. The excellent properties of PDA, such as strong adhesion, photothermal and high drug-loaded capacity, seem to be born for tissue repair and regeneration. Furthermore, PDA combined with different materials can exert unexpected effects. Thus, to inspire researchers, this review summarizes the recent and representative development of PDA biomaterials in tissue repair and regeneration. This article focuses on why apply PDA in these biomaterials and what PDA can do in different tissue injuries.

“…In particular, the aligned nanofibrous topography facilitates directional cell growth and promotes peripheral nerve regeneration . We previously reported that random PPy/PDA/PLLA nanofibers with a three-layer core–shell structure have higher electrical conductivity than PLLA nanofibers . However, the effects of the conductive PPy shell on the piezoelectric properties of the composite scaffold and the effects of the aligned piezoelectric conductive scaffold on the behaviors of nerve cells, neural regeneration, and related mechanisms remain unclear.…”

“…To date, nanofibrous membranes prepared by electrostatic spinning have been progressively developed as hemostatic materials due to their large surface area and fibrous structure. Owing to their strong capacity for facilitating the entrapment of blood cells, platelets, and other coagulation factors, these materials present high efficiencies in terminating bleeding when compared to sponges or other membranes. − For example, Ke et al fabricated a series of biocompatible and hemostatic nanofibers using soy protein isolate and poly( l -lactic acid) by high-voltage electrospinning, which presented a hemostatic effect similar to that of a commercial gelatin sponge. An in vivo assay upheld the excellent hemostatic effect and the promotion of wound healing.…”

One cannot overstate the advantages of an ideal hemostasis material for the emergency rescue of wars and traffic accident victims, and it can significantly mitigate patient distress and minimize threat to life. Nonetheless, it is still a daunting task to obtain a hemostasis material encompassing desirable advantages, including safety, antibacterial activity, high efficiency, sufficient mechanical strength, cost-effectiveness, and so on. In this study, a one-step electrospinning strategy for achieving an efficient hemostatic membrane with a Janus structure is provided. Owing to the synergistic coagulation effect between gelatin nanofibers and zeolite powders (hydrophilic layer), the membrane exhibits excellent coagulation performance in vitro. Simultaneously, the hydrophobic layer's efficacy in preventing blood permeation further shortens bleeding time and lessens blood loss in vivo. Moreover, the membrane presents commendable flexibility, antibacterial activity, hemocompatibility, and noncytotoxicity, with promise to be used as a safe and efficient hemostatic dressing in clinical applications.
