Microcontact printing (μCP) is a soft lithography technique used to create patterns on substrates at the micron and nanometer scales. This technique leverages the use of a stamp, usually made from an elastomeric material like polydimethylsiloxane (PDMS), to transfer molecules of "ink" onto a surface. The ink can be anything from proteins to nanoparticles, allowing for a wide range of applications in nanotechnology.
