Microcontact printing.
Microcontact printing (μCP) is a useful technique for transferring certain molecules onto surfaces with high spatial resolution using elastomeric stamps. The stamp for μCP is fabricated by replica molding from a master made by microlithography. After wetting with a type of material as an "ink," the stamp comes into contact with the substrate. The ink is selectively transferred onto parts of the substrate wherever the stamp makes direct contact, to generate patterns and structures with designated features. Self-assembled monolayers (SAMs) and μCP are useful in many different fields, e.g., in the studies of protein adsorption, cell attachment, and in the construction of sensors.
