Abstract

Hemostasis and subsequent anti-inflammatory measures are essential for wound healing in the human body following trauma or surgical procedures. Here, we try to use the dragging effect of a brush to prepare a Janus hydrogel with the least amount of bacteriostatic agent. The synthesized suspension of polyvinylbenzene-silica@quaternary ammonium salt (PDVB-SiO2@NR4+) Janus particles (JNPs) was selected as ink and brush coated onto one side of a polyacrylic acid (PAA) hydrogel, resulting in Janus hydrogel (JNPs≌PAA). The anisotropic chemical composition, wetting properties, adhesion capabilities, and the obtained hemostatic performance of the Janus hydrogel were studied thoroughly. The hydrophilic PAA side promoted tissue adhesion, while the hydrophobic JNPs side exhibited antibacterial effects. The Janus hydrogel presented perfect hemostatic effect in vivo, owing to the procoagulant effect of the adhesive layer, negative charges, and blood-blocking properties of the hydrophobic layer. The presence of quaternary ammonium groups in the Janus hydrogel imparted strong antibacterial activity against E. coli and S. aureus. Furthermore, the Janus hydrogel showed a low hemolysis rate and high cell safety. This multifunctional hydrogel material holds great promise for wound treatment and expands the applications of hydrogel materials in the biomedical field.
利用刷子的拖拽效应制备的单侧抗菌 Janus 水凝胶止血敷料。
止血和随后的抗炎措施对于创伤或外科手术后人体伤口愈合至关重要。在这里,我们尝试利用刷子的拖拽作用来制备一种含有最少抑菌剂的Janus水凝胶。将合成的polyvinylbenzene-silica@quaternary铵盐(PDVB-SiO2@NR4+) Janus颗粒(JNPs)悬浮液作为墨水和毛笔涂覆在聚丙烯酸(PAA)水凝胶的一侧,得到Janus水凝胶(JNPs≌PAA)。研究了Janus水凝胶的各向异性化学成分、润湿性能、粘附性能和止血性能。亲水性PAA侧促进组织粘附,疏水性JNPs侧具有抗菌作用。Janus水凝胶由于其黏附层的促凝作用、负电荷和疏水层的血阻特性,在体内表现出了较好的止血效果。由于季铵基团的存在,Janus水凝胶对大肠杆菌和金黄色葡萄球菌具有较强的抗菌活性。此外,Janus水凝胶表现出低溶血率和高细胞安全性。这种多功能水凝胶材料在伤口治疗方面具有很大的前景,扩大了水凝胶材料在生物医学领域的应用。

期刊介绍: Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields. Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication. The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
