Abstract
Nanocellulose is not only a renewable material but also brings functions that are opening new technological opportunities. Here we discuss a special subset of this material, in its fibrillated form, which is produced by aerobic microorganisms, namely, bacterial nanocellulose (BNC). BNC offers distinct advantages over plant-derived counterparts, including high purity and high degree of polymerization as well as crystallinity, strength, and water-holding capacity, among others. More remarkably, beyond classical fermentative protocols, it is possible to grow BNC on non-planar interfaces, opening new possibilities in the assembly of advanced bottom-up structures. In this review, we discuss the recent advances in the area of BNC-based biofabrication of three-dimensional (3D) designs by following solid- and soft-material templating. These methods are shown as suitable platforms to achieve bioadaptive constructs comprising highly interlocked biofilms that can be tailored with precise control over nanoscale morphological features. BNC-based biofabrication opens applications that are not possible by using traditional manufacturing routes, including direct ink writing of hydrogels. This review emphasizes the critical contributions of microbiology, colloid and surface science, as well as additive manufacturing in achieving bioadaptive designs from living matter. The future impact of BNC biofabrication is expected to take advantage of material and energy integration, residue utilization, circularity and social latitudes. Leveraging existing infrastructure, the scaleup of biofabrication routes will contribute to a new generation of advanced materials rooted in exciting synergies that combine biology, chemistry, engineering and material sciences.

Int J Biol Macromol 2024; 259:129033. [PMID: 38176505 DOI: 10.1016/j.ijbiomac.2023.129033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 12/19/2023] [Accepted: 12/22/2023] [Indexed: 01/06/2024]
Abstract
Skin wounds are repaired by a complex series of events and overlapping phases in which bacterial infection and insufficient angiogenesis at the wound site delay the healing process. Thus, functional wound dressings with enhanced antibacterial activity and angiogenic capacity have attracted attention. Herein, bacterial cellulose (BC)-based dressings were successfully fabricated by functionalization with a polydopamine (PDA) coating and copper sulfide nanoparticles (CuS NPs). Under 808 nm laser illumination, the BC/PDA/CuS composite membranes exhibited outstanding adjustable photothermal and photodynamic activities as well as controlled Cu2+ release, endowing the composite membranes with synergetic antibacterial activity. Specially, a bactericidal efficiency of 99.7 % and 88.0 % for Staphylococcus aureus and Escherichia coli was achieved after treatment with BC/PDA/CuS5 sample under NIR irradiation (0.8 W/cm2, 10 min), respectively. Moreover, the BC/PDA/CuS5 composite membrane could enhance the angiogenesis due to the released Cu2+. In vivo experiments revealed that the BC/PDA/CuS5 composite membrane dressing could accelerate the wound closure process of the full-thickness skin defects with S. aureus by synergistically reducing inflammation, enhancing collagen deposition, and promoting vascularization under NIR irradiation. Additionally, the BC/PDA/CuS5 composite membrane exhibited high biocompatibility and biosafety. This work offers a new strategy to prepare multifunctional BC-based dressing for clinical wound healing.
