Abstract
Poly(dimethylsiloxane) stamps for microcontact printing with polar inks, wh ich no longer need to be reactivated after each printing step, are revealed . The silicone surface is modified by linking a hydrophilic polyethylene gl ycol chain to SiOH groups created on the surface of the stamp. While stamps that are oxidized conventionally become useless 3 h after their preparatio n (Figure top), the PEG-modified stamps can still print high-quality patter ns after 20 days (Figure bottom).
