The cover picture features the wet stamping (WETS) technique, which uses metal nanoparticles as "dynamic inks" to print colored micropatterns. Color changes are due to the aggregation and dispersion of the particles and the electrodynamic coupling between their metal cores. The patterns can be erased by chemical means and can also act as pH sensors. For more information, please read the Communication "Rewritable and pHSensitive Micropatterns Based on Nanoparticle 'Inks'" by B. A. Grzybowski and coworkers, beginning.
