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

Herein, we report a modified microcontact printing (μCP) 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 which have been surface-functionalised with grafted polymers. This improvement was evaluated by a profound software-assisted statistical analysis.
