Solid-Phase Microcontact Printing for Precise Patterning of Rough Surfaces: Using Polymer-Tethered Elastomeric Stamps for the Transfer of Reactive Silanes

Autor: Pinar Akarsu, Stefan Reinicke, Richard Grobe, Martin Reifarth, Marcel Sperling, Alexander Böker, Julius Nowaczyk, Matthias Hartlieb

Publikováno v: ACS Applied Polymer Materials

We present a microcontact printing (μCP) routine suitable to introduce defined (sub-) microscale patterns on surface substrates exhibiting a high capillary activity and receptive to a silane-based chemistry. This is achieved by transferring function

Xanthate-supported photo-iniferter (XPI)-RAFT polymerization: Facile and rapid access to complex macromolecular architectures

Autor: Anne-Catherine Lehnen, Alain Bapolisi, Martin Reifarth, Marek Bekir, Matthias Hartlieb

Xanthate-supported photo-iniferter (XPI)-reversible addition-fragmentation chain-transfer (RAFT) polymerization is introduced as a fast and versatile photo-polymerization strategy. Small amounts of xanthate are added to conventional RAFT polymerizati

A Dual pH‐ and Light‐Responsive Spiropyran‐Based Surfactant: Investigations on Its Switching Behavior and Remote Control over Emulsion Stability

Autor: Martin Reifarth, Marek Bekir, Alain M. Bapolisi, Evgenii Titov, Fabian Nußhardt, Julius Nowaczyk, Dmitry Grigoriev, Anjali Sharma, Peter Saalfrank, Svetlana Santer, Matthias Hartlieb, Alexander Böker

Publikováno v: Angewandte Chemie International Edition. 61

A cationic surfactant containing a spiropyran unit is prepared exhibiting a dual-responsive adjustability of its surface-active characteristics. The switching mechanism of the system relies on the reversible conversion of the non-ionic spiropyran (SP

3rd generation poly(ethylene imine)s for gene delivery

Autor: Anja Traeger, Matthias Hartlieb, Philipp S. Borchers, Tanja Bus, Christoph Englert, Antje Vollrath, Martin Reifarth, Stephanie Hoeppener, Ulrich S. Schubert

Publikováno v: Journal of materials chemistry. B. 5(6)

Cationic polymers play a crucial role within the field of gene delivery offering the possibility to circumvent (biological) barriers in an elegant way. However, polymers are accompanied either by a high cytotoxicity or low efficiency. In this study,

Tailoring patches on particles: a modified microcontact printing routine using polymer-functionalised stamps

Autor: Martin Reifarth, Marcel Sperling, Richard Grobe, Alexander Böker

Publikováno v: Chemical Communications

Herein, we report a modified microcontact printing (mu CP) routine suitable to introduce particle patches of a low molecular weight ink (LMWI) on porous SiO2 microparticles. Thereby, patch precision could be significantly improved by utilising stamps
