Patchy Particles
In article number 2301761, Alexander Böker, Matthias Hartlieb, Martin Reifarth, and co‐workers provide a modified microcontact printing (μCP) routine, which they use to introduce highly functional patches on silicon dioxide (SiO2) microspheres. The μCP method uses a polymer brush‐functionalized elastomeric stamp, whose surface features have been optimized to print amino‐functional...
Their inherent directional information renders patchy particles interesting building blocks for advanced applications in materials science. In this study, a feasible method to fabricate patchy silicon dioxide microspheres is demonstrated, which they are able to equip with tailor‐made polymeric materials as patches. Their fabrication method relies on a solid‐state supported microcontact printing (µCP)...
