摘要:

The interaction of engineering and life sciences has a long history and one of the most important aspects of this fruitful collaboration regards the functional interfacing of technical systems with biological specimens. We are developing tailored biointerfaces by using `DNA surface technology’, taking advantage of DNA biochips that can be functionalized through specific Watson-Crick hybridization to facilitate the self-assembly of complex surface architectures bearing bioactive components. Essential approaches include surface chemistry, (bio)orthogonal coupling strategies for site-selective protein modification as well as concepts from ‘structural DNA nanotechnology’. These ‘bottom-up’ methods are complemented with ‘top-down’ fabrication processes, such as polymer pen lithography and microfluidics, to develop instrumentation and devices for the analysis of cellular systems and the establishment of biotechnological processes. I will present recent case studies from our work concerning the development of multiscale systems for biocatalytic cascade reactions and the investigation of cellular adhesion and signaling.
