A facile method to fabricate an antimicrobial coating based on poly(1?vinyl?3?allylimidazolium iodide) (PAVI) and poly(ethylene glycol) dimethyl acrylate (PEGDMA)
Biomedical device-related infections have been a great concern over the past decades. In this work, cationic macromolecules poly(1-vinyl-3-allylimidazolium iodide)
(PAVI) with antibactericidal ability were prepared and grafted on nose clips by surface-initiated polymerization via plasma/autoclaving method. The precursor poly(1-
vinylimidazole) was synthesized by surface-initiated polymeriz...

【JMCB-2017年夏季】A self-defensive antibacterial coating acting through the bacteria-triggered release of a hydrophobic antibiotic from layer-by-layer films
Drug delivery systems play important roles in the construction of antibacterial coatings on the surfaces
of biomaterials. However, excessive release of antibiotics in the environment can lead to the generation
of resistant bacteria. A methoxy poly(ethylene glycol)-poly(e-caprolactone)-chitosan (MPEG-PCL-CS)
block polymer was prepared through covalent grafting of CS onto MPEG-PCL. MPEG-P...

【Composites Science and Technology】Rapid and efficient synthesis of isocyanate microcapsules via thiol-ene photopolymerization in Pickering emulsion and its application in self-healing coating
We report an efficient and novel method for encapsulation of isophorone diisocyanate (IPDI) in polythioether microcapsules via thiol-ene click reaction based on Pickering emulsion, which has significantly improved and simplified the preparation process. The resultant microcapsules have spherical shapes with a layer of poly(glycidyl methacrylate) (PGMA) particles covering outside. The diamete...

【Biomaterials Science-【Cover Page】2016年秋季】Construction of a temperature-responsive terpolymer coating with recyclable bactericidal and self-cleaning antimicrobial properties
Once a biomedical implant is
implanted into a human body, proteins and bacteria can easily colonize the
implant, and subsequently, a biofilm can grow on the surface. A biofilm can protect
the inhabiting bacteria against macrophages and neutrophil cell attack from the
host immune system. The most important issue for artificial antibacterial
surfaces is the accumulation of the bacte...

Biodegradable Microcarriers of Poly(Lactide-co-Glycolide) and Nano-Hydroxyapatite Decorated with IGF-1 via Polydopamine Coating for Enhancing Cell Proliferation and Osteogenic Differentiation
Abstract
In this study, insulin-like growth factor 1 (IGF-1) was successfully immobilized on the poly(lactide-co-glycolide)/hydroxyapatite (PLGA/HA) and pure PLGA microcarriers via polydopamine (pDA). The results demonstrated that the pDA layer facilitated simple and highly efficient immobilization of peptides on the microcarriers within 20?min. Mouse adipose-derived stem cells (ADSCs) attach...

氮气流量对金刚石膜生长的影响研究
关键字：金刚石膜 氮气 生长速率 表面形貌 膜品质 EA-CVD方法
采用电子辅助化学气相沉积法(EA-CVD)制备掺氮金刚石薄膜，研究了不同氮气流量对金刚石膜的生长速率、表面形貌和膜品质的影响。实验发现，在较低的氮气流量下，金刚石膜的生长速率增加，在较高的氮气流量下生长速率减小。利用SEM、Raman光谱、XPS等测试手段对样品的表面形貌及品质进行了表征。结果表明，当氮气流量为4sccm时金刚石膜的结晶比较完整；当氮气流量为8sccm时生成与(100)面共存的“菜花状”。氮气流量的进一步增加，“菜...
