Int J Biol Macromol 2024; 271:132355.

Abstract
In this paper, a novel programable sewage-cleaning technology for the regeneration of antibacterial nanocomposites via the removal of wastewater pollutants is presented. Montmorillonite (MMT) was encapsulated in poly(vinyl alcohol) (PVA)-enhanced chitosan (CTS) hydrogels to form MMT-loaded nanocomposite biofilms (PCM). The PCM nanocomposite biofilms exhibited increased breaking strength and elongation at break, by factors of approximately 1.38 and 1.40, respectively, compared with those of the pure PVA/CTS biofilms. The maximum adsorption capacity of the PCM nanocomposite biofilms toward tetracycline and Ag(I) is 275.0 and 567.0 mg/g, respectively. The adsorbed nanocomposite biofilms exhibited excellent antibacterial properties against Staphylococcus aureus and Escherichia coli. Meanwhile, the nanocomposite also showed an effective adsorption capacity toward other toxic components, where the highest adsorption capacity is 2748.0 mg/g (for methyl blue). The simulation results indicated that the adsorption behaviors of the malachite green, neutral red, methyl blue, tetracycline, Cu(II), Zn(II), and Ag(I) by the PCM nanocomposite biofilms followed pseudo-second-order kinetic and Freundlich isotherm models. Furthermore, the PCM nanocomposite biofilms are stable in PBS solution but degradable in lysozyme-containing PBS solution, suggesting their potential application in the wastewater treatment as well as antibacterial fields.

Abstract
Bleeding to death accounts for around 30-40% of all trauma-related fatalities. Current hemostatic materials are mainly mono-functional or have insufficient hemostatic capacity. Nanoclay has been recently shown to accelerate hemostasis, improve wound healing, and provide the resulting multifunctional hemostatic materials antibacterial, anti-inflammatory, and healing-promoting due to its distinctive morphological structure and physicochemical properties. Herein, the chemical design and action mechanism of nanoclay-based hemostatic, antibacterial, and pro-wound healing materials in the context of wound healing are discussed. The physiological processes of hemostasis and wound healing to elucidate the significance of nanoclay for functional wound hemostatic dressing design are outlined. A summary of the features of various nanoclay and product types used in wound hemostatic dressings is provided. Nanoclay can be antimicrobial due to the slow release of metal ions and has an abundant surface charge allowing for high affinity for proteins and cells, which can activate the coagulation reaction or facilitate tissue repair. Nanoclay with a microporous structure can be used as drug carriers to create composites critical for inhibiting bacterial growth on wounds or promoting the regeneration of vascular, muscle, and skin tissues. Directions for further research and innovation of nanoclay-based multifunctional materials for hemostasis and tissue regeneration are explored.

Front Bioeng Biotechnol 2024; 11:1288393. [PMID: 38239917 PMCID: PMC10794388 DOI: 10.3389/fbioe.2023.1288393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 12/14/2023] [Indexed: 01/22/2024] Open
Abstract
Healing of severe fractures and bone defects involves many complex biological processes, including angiogenesis and osteogenesis, presenting significant clinical challenges. Biomaterials used for bone tissue engineering often possess multiple functions to meet these challenges, including proangiogenic, proosteogenic, and antibacterial properties. We fabricated lithium and cobalt co-doped mesoporous bioactive glass nanoparticles (Li-Co-MBGNs) using a modified sol-gel method. Physicochemical analysis revealed that the nanoparticles had high specific surface areas (>600 m2/g) and a mesoporous structure suitable for hydroxyapatite (HA) formation and sustained release of therapeutic ions. In vitro experiments with Li-Co-MBGNs showed that these promoted angiogenic properties in HUVECs and pro-osteogenesis abilities in BMSCs by releasing Co2+ and Li+ ions. We observed their antibacterial activity against Staphylococcus aureus and Escherichia coli, indicating their potential applications in bone tissue engineering. Overall, our findings indicate the feasibility of its application in bone tissue engineering.
