Abstract

This study reports the synthesis of ultrathin polymeric films through layer-by-layer deposition and covalent cross-linking of poly(2-vinyl-4,4'-dimethylazlactone) and branched poly (ethylene imine) (PEI) which were functionalized with aromatic amines that encompass anilines. To assess the effect of these aromatics molecules on the adhesion and proliferation of Langerhans β-cells, we prepared 35 bilayers of unfunctionalized and functionalized films with aromatic amines, which were characterized in terms of their physical, chemical, and biological properties by a battery of experimental techniques including 1H and 13C, NMR, mass spectrometry, attenuated total reflectance Fourier transform infrared spectroscopy, field emission scanning electron microscopy and cell adhesion and staining. The films were nanometric, transparent, resistant to manipulation, chemically reactive, and highly cytocompatible. We demonstrated that films functionalized with aromatic molecules support the attachment and growth of in vitro Langerhans β-cells. This study provides the basis for a general approach to designing and functionalizing ultrathin films that promote cell growth on surfaces of interest for investigation in cell biology studies and a broad range of other biomedical applications.   Resumen.

Para evaluar el efecto de estas moléculas aromáticas en la adhesión y proliferación de las células β de Langerhans, se prepararon películas de 35 bicapas y se funcionalizaron con aminas aromáticas; se caracterizaron en términos de sus propiedades físicas, químicas y biológicas mediante una serie de técnicas experimentales que incluyeron 1H y 13C, RMN, espectrometría de masas, espectroscopia de infrarrojo por transformada de Fourier, microscopía electrónica de barrido por emisión de campo y tinción celular.

用芳香胺制作反应性功能微膜并将其应用于朗格汉斯细胞的生长
本研究报告介绍了通过逐层沉积和共价交联聚(2-乙烯基-4,4'-二甲基氮内酯)和支化聚(乙烯亚胺)(PEI)合成超薄聚合物薄膜的方法,这些聚(2-乙烯基-4,4'-二甲基氮内酯)和支化聚(乙烯亚胺)(PEI)被芳香胺(包括苯胺)功能化。为了评估这些芳香族分子对朗格汉斯 β 细胞粘附和增殖的影响,我们制备了 35 层未官能化和官能化的芳香族胺薄膜,并通过一系列实验技术,包括 1H 和 13C、核磁共振、质谱、衰减全反射傅立叶变换红外光谱、场发射扫描电子显微镜以及细胞粘附和染色,对这些薄膜的物理、化学和生物特性进行了表征。这些薄膜呈纳米级、透明、耐操纵、化学反应性强、与细胞高度兼容。我们证明,芳香分子功能化薄膜支持体外朗格汉斯 β 细胞的附着和生长。这项研究为设计和功能化超薄薄膜的一般方法奠定了基础,这种薄膜可促进细胞在感兴趣的表面上生长,用于细胞生物学研究和其他广泛的生物医学应用。 概述。本研究介绍了通过逐层技术合成超薄聚合物薄膜,以及支化聚(2-乙烯基-4,4'-二甲基氮内酯)和聚乙烯亚胺(PEI)与包括苯胺在内的芳香胺的共价交联。为了评估这些芳香族分子对 β 朗格汉斯细胞粘附和增殖的影响,制备了 35 层双层膜,并用芳香族胺进行了功能化处理;使用一系列实验技术(包括 1H 和 13C、核磁共振、质谱分析、傅立叶变换红外光谱、场发射扫描电子显微镜和细胞染色)对这些薄膜的物理、化学和生物特性进行了表征。总体而言,这些薄膜具有纳米级、透明、防篡改、化学反应性和高度细胞相容性。研究还表明,芳香分子功能化薄膜能促进β细胞在体外的粘附和生长。这项研究为在细胞生物学研究感兴趣的表面上设计和功能化促进细胞生长的超薄薄膜,以及广泛的潜在生物医学应用奠定了基础。

期刊介绍: The Journal of the Mexican Chemical Society (J. Mex. Chem. Soc.) is a scientific, blind, peer reviewed, and open access, free of charge publication that covers all areas of chemistry and its sub-disciplines (i.e. medicinal chemistry, natural products, electrochemistry, material science, computational chemistry, organic chemistry, bionirganic chemistry, etc). It is devoted to facilitating the worldwide advancement of our understanding of chemistry. It will primarily publish original contributions of research in all branches of the theory and practice of chemistry in its broadest context as well as critical reviews in active areas of chemical research where the author has published significant contribution. The J. Mex. Chem. Soc. is a quarterly publication which language of submission and publication is English. To be suitable for publication in J. Mex. Chem. Soc., manuscripts must describe novel aspects of chemistry, high quality of results and discussion an excellent bibliographic support, and contribute to the development of the field. Routine or incremental work are not suitable for publication in J. Mex. Chem. Soc. Authors are encouraged to send contributions in electronic form. Our online submission system guides you stepwise through the process of entering your article details and uploading your files.
