Abstract(#br)All-solution-processed, easily-made, flexible multi-walled carbon nanotube (MWCNT)/polydimethylsiloxane (PDMS)-based electrodes were fabricated and used for electrochemical DNA sensors. These electrodes could serve as a recognition layer for DNA, without any surface modification, through π–π interactions between the MWCNTs and DNA, greatly simplifying the fabrication process for DNA sensors.

Abstract(#br)Modern light wearable electrical devices require flexible, conductive materials for the development of portable and/or wearable devices. In this study, a flexible carbon nanotube (CNT) electrode is prepared, and the conductive CNTs are deposited on a flexible polydimethylsiloxane (PDMS) substrate using a combination of inkjet printing and transfer printing methods. Aqueous CNT ink is printed on a commercial overhead projector film.

在过去的几十年里，神经接口在揭示神经网络和帮助瘫痪患者方面发挥着至关重要的作用。随着顺应性和长寿命成为神经接口的关键问题，柔性材料越来越多地参与此类器件的开发。然而，由于聚二甲基硅氧烷( PDMS )与硅微加工技术的不相容性，金属与PDMS之间的热膨胀系数不同，使得PDMS器件的发展受到了困扰。这里，采用中间的Parylene A C层，通过单一的Awafer加工，开发了PDMSA基电极阵列，该电极阵列制作稳定、简单，易于微型化和与其他元件集成。研制的电极阵列可通过小鼠体内实验检测视觉诱发电位( VEPs )。共形接触和高空间分辨率是通过检测所有16个通道的有区别的VEP来实现的。为考察电极尺寸对信号质量的影响，采用了3种不同直径的20 ~ 120°µ m，导致电极尺寸与信号质量之间没有明确的相关性。所研制的器件显示了PDMSHA基生物电子学在各种应用中的潜力，其灵活性和符合性以及器件的鲁棒性都是需要的。
