Micro Contact Printing: Basics and Applications

This lecture covers the fundamentals of microcontact printing (UCP), including the process of mold creation, polymerization, and stamping with ink solutions. It explores high-resolution UCP techniques, showcasing examples of stamp patterns and their corresponding printed features. The instructor discusses the importance of achieving conformal contact between soft stamps and hard substrates, highlighting the impact of stamp properties on the printing process. Various examples of layered hybrid stamps are presented, demonstrating their adaptability to different substrates. The lecture also addresses common problems and limitations in microcontact printing, such as lateral collapse and sagging. Additionally, the scope of the lecture includes an overview of nano-fabrication methods, focusing on achievements and challenges in the field.
