Printing Technologies for Integration of Electronic Devices and Sensors

Publikováno v: Functional Nanostructures and Sensors for CBRN Defence and Environmental Safety and Security ISBN: 9789402419085

Many different methods, such as screen printing, gravure, flexography, inkjet etc., have been employed to print electronic devices. Depending on the type and performance of the devices, processing is done at low or high temperature using precursor- o

Locally Controlled Growth of Individual Lambda-Shaped Carbon Nanofibers

Autor: Uwe Bog, Christian Kübel, Tobias Loritz, Chethala Neelakandhan Shyam Kumar, Sharali Malik, Michael Bruns, Christian Greiner, Hendrik Hölscher, Christian Lutz, Julia Syurik, Michael Hirtz

Publikováno v: Small

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 na

Polymer Pen Lithography with Lipids for Large-Area Gradient Patterns

Autor: Uwe Bog, Quinn Rainer, Souvik Ghosh, Harald Fuchs, Ainhoa Urtizberea, Steven Lenhert, Michael Hirtz, Ravi Kumar

Publikováno v: Langmuir : the ACS journal of surfaces and colloids. 33(35)

Gradient patterns comprising bioactive compounds over comparably (in regard to a cell size) large areas are key for many applications in the biomedical sector, in particular, for cell screening assays, guidance, and migration experiments. Polymer pen

Clickable Antifouling Polymer Brushes for Polymer Pen Lithography

Autor: Andrea E. Holmes, Michael Hirtz, Andres de los Santos Pereira, Viviana Parrillo, Summer L. Mueller, Uwe Bog, Shana Havenridge, Cesar Rodriguez-Emmenegger, Harald Fuchs, Michael Bruns

Publikováno v: ACS applied materialsinterfaces. 9(13)

Protein-repellent reactive surfaces that promote localized specific binding are highly desirable for applications in the biomedical field. Nonspecific adhesion will compromise the function of bioactive surfaces, leading to ambiguous results of bindin

Site-Specific Surface Functionalization via Microchannel Cantilever Spotting (µCS): Comparison between Azide-Alkyne and Thiol-Alkyne Click Chemistry Reactions

Autor: Seyed Mohammad Mahdi Dadfar, Uwe Bog, Michael Hirtz, Sylwia Sekula-Neuner, Vanessa Trouillet

Publikováno v: Small. 14:1800131

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-alky

Biosensing: Densely Packed Microgoblet Laser Pairs for Cross-Referenced Biomolecular Detection (Adv. Sci. 10/2015)

Autor: Falko Brinkmann, Michael Hirtz, Tobias Wienhold, Timo Mappes, Harald Fuchs, Christian Koos, Sarah Kraemmer, Uwe Bog, Heinz Kalt, Sebastian Koeber, S. F. Wondimu

Publikováno v: Advanced Science

In article 1500066, U. Bog, M. Hirtz, and co‐workers demonstrate on‐chip biomolecular sensing using whispering‐gallery‐mode microgoblet lasers. Biomolecular detection is usually affected by signal disturbances, induced by refractive index and
