Microcontact Insertion Printing. Left: Single molecules are inserted into a preexisting layer in microscopic regions that are defined by a patterned elastomeric stamp. Right: Complex and overlapping chemical patterns can be fabricated employing multiple stamping steps. (scanning electron micrograph, field of view 90 µm x 90 µm)
A new process for creating patterns of individual molecules on a surface combines control of self-assembled monolayers (SAMs) and a soft lithography technique known as microcontact printing. Scientists use the process, known as "microcontact insertion printing" to build surfaces that have molecules with specific functions inserted at known intervals on a surface.
