Abstract(#br)Direct chemical bonding of biomolecules to the surface of chemically inert polymers such as polydimethylsiloxane (PDMS) is not easily achieved. Therefore, pre-activation of such materials, followed by attachment of the biomolecule is necessary.(#br)This paper describes a procedure to functionalize a PDMS surface by oxygen-based plasma followed by the adhesion of collagen type I for the preparation of adhesive-free bilayer composite intended as skin substitute.

Abstract(#br)The purpose of this study was to investigate the effects of scaffold surface morphology on cell adhesion and survival rate in vitreous cryopreservation of tenocyte-scaffold constructs. Tenocytes were obtained from tail tendons of rats. Polydimethylsiloxane (PDMS) was used to fabricate three types of scaffolds with varying surface morphological characteristics, i.e., smooth, micro-grooved, and porous surfaces, respectively. The tenocytes were seeded on the surfaces of the scaffolds to form tenocyte-scaffold constructs.

摘要\n物联网( IoT )因其多样的应用和市场潜力而日益普及。他们更多地被推到偏远的地点，开发人员寻找永远的电源。振动能量采集器( EH )能够缓解供电问题。采用氧化锌( ZnO )、聚二甲基硅氧烷( PDMS )和银( Ag )。但观察到薄膜晶粒尺寸有很大影响，即大晶粒薄膜优于小晶粒薄膜。本文分析了影响参数并进行了相关实证研究。采用扫描电子显微镜( SEM )、X射线衍射( XRD )、电学表征等方法进行了深入分析。观察到本工作实现了46.92µWpeak / 15.03µWrms功率。
