In article number 1803944, Michael Hirtz, Hendrik Holscher, and co‐workers report on the controlled growth of carbon nanofibers (CNFs) in ∧‐ or λ‐type shape in a facile open ethanol flame process. The location and number of CNFs can be precisely controlled down to a single CNF via scanning probe lithography delivered catalytic salt features. An empirical model is suggested for the growth process evolution...
The locally defined growth of carbon nanofibers with lambda shape in an open flame process is demonstrated. Via the growth time, the geometry of the structures can be tailored to a Λ‐ or λ‐type shape. Microchannel cantilever spotting and dip‐pen nanolithography are utilized for the deposition of catalytic salt NiCl2 · 6H2O for locally controlled growth of lambda‐shaped carbon nanofibers. Rigorous...
Different types of click chemistry reactions are proposed and used for the functionalization of surfaces and materials, and covalent attachment of organic molecules. In the present work, two different catalyst‐free click approaches, namely azide–alkyne and thiol–alkyne click chemistry are studied and compared for the immobilization of microarrays of azide or thiol inks on functionalized glass surfaces...
We present our latest results on microgoblet lasers as biosensors. Surface functionalization is performed with high resolution and throughput by aligned microcontact stamping. We show simultaneous device readout, the resulting cross-referencing capabilities and functionalization reconfiguration.
We report on the fabrication of polymeric whispering-gallery mode (WGM) lasers. Our approach enables high packing density by vertical stacking and multiplexed readout of resonators and lends itself to signal referencing or multi-target sensing.
We report on polymeric high-Q microresonators and a method for spatially selective functionalization. Furthermore we present coupled resonators exhibiting a higher bulk refractive index sensitivity than single resonators making them promising candidates for high-sensitivity sensing.
Meeting the need of biomedical users, we develop disposable Lab-on-a-Chip systems based on commercially available polymers. We are combining passive microfluidics with active optical elements on-chip by integrating multiple solid-state and liquid-core lasers. While covering a wide range of laser emission wavelengths, the chips have the size of microscope cover slips and use optical and fluidic interconnects...
We develop optical Lab-on-a-Chips on different platforms for marker-based and label-free biophotonic sensor applications. Our chips are based on polymers and fabricated by mass production technologies to integrate microfluidic channels, optical waveguides and miniaturized lasers.
