Microcontact Printing

Microcontact printing is a technique used to create detailed patterns on surfaces at a microscopic level. It involves using a flexible stamp, often made of rubber, that has a pattern etched into its surface. The stamp is coated with a material, such as ink or a chemical, which is then transferred onto a substrate—like a silicon wafer or glass—when the stamp is pressed onto it. This method allows precise, efficient patterning for applications in electronics, nanotechnology, and biology, enabling the creation of tiny, intricate designs essential for advanced device fabrication and surface modification.
