Convenient surface functionalization of whole-Teflon chips with polydopamine coating

This paper presents a convenient strategy to modify the surface of whole-Teflon microfluidic chips by coating the channel walls with a thin layer of polydopamine (PDA) film, which is formed by oxidation-induced self-polymerization of dopamine in alkaline solution. Two coating strategies, static incubation and dynamic flow, are demonstrated and used for tuning the physical and chemical properties of the coated channel walls. The functionalized surfaces were investigated with the contact angle, X-ray photoelectron spectroscopy, and atomic force microscopy measurements. The coating time was optimized according to the fluorescent intensity of the green fluorescent protein immobilized on the modified surface. Applications of the PDA-modified Teflon microchips in bioanalysis were demonstrated with a typical sandwich immunoassay. Moreover, long-term cell culture experiments on modified and native Teflon chips revealed that the chip biocompatibility can be greatly improved with PDA coating. The results indicate that the surface properties of the Teflon can be easily controlled by the PDA modification, thus greatly expanding the application scope of whole-Teflon chips for various chemical and biological research fields.     

L∞-gain analysis for positive singular time-delay systems

This paper is devoted to the characterization of L_∞-gain for positive singular systems with time-varying delays. First, we introduce an augmented system to replace the original system in order to analyze the positivity of singular systems with time-varying delays. By investigating the monotonicity of state trajectory, the L_∞-gain for singular system with constant delays is characterized. Then, by comparing the trajectories of time-varying delay system and constant delay case, we finally propose the L_∞-gain for singular system with time-varying delays. It is shown that the L_∞-gain of positive singular systems is independent of the magnitude of delays.     

学术期刊编辑思维定式的误区

当代一些学术期刊编辑受传统思维模式的影响和制约,形成了重整体、重综合、崇尚圣贤经典的价值取向,使办刊过程中产生了许多误区,刊物平庸无奇,缺少个性与生机.认为期刊要发展、要同世界接轨,必须调整和革新编辑的思维模式与价值取向.
