Synthetic chemistry in microdevices and lab on chip technology are technically demanding research fields requiring extensive technical development for their fusion. Therefore, the aim of project 8 is to work on the technical aspects of integrating analysis and synthesis systems in microfluidics and provide the findings and respective enabling technology to the whole research unit. Specifically, the project aims to hyphenate droplet microfluidics and on-chip chromatography to enable the reading of the chemical contents of single droplets. Furthermore, a novel approach for manufacturing microfluidic devices will be investigated to give all project partners rapid access to tailor-made high quality microfluidic devices. For this purpose, the technology of selective laser etching will be explored and further developed to give access to microfluidic chips made from glass, quartz and sapphire. Furthermore approaches will be developed to equip these structures with metal electrodes. Important application in the context of the research unit are chip-integrated bioimpedance spectroscopy and chip interfacing with electrospray mass spectrometry, as well as with ion mobility spectrometry. In this way, project 8 serves as a technology bridge between the research unit’s projects providing essential technical expertise and furthering the state of the art in integrated micro laboratories.
