본문내용

- Soft lithography represents an alternative set of techniques for fabricating micro- and nanostructures
- The original version of this technology employed an elastomeric stamp (or mold) to pattern a wide variety of materials such as self-assembled monolayers (SAMs), colloids, inorganic solids, proteins, and cells.
- Originally developed in the laboratory of Professor George M. Whitesides at Harvard University

PDMS (Polydimethylsiloxane)
PDMS is chemically inert

PDMS provides a surface that has low interfacial free energy (ca. 21.6 x 10-3 Jm-2)

PDMS is homogeneous and optically transparent down to about 300nm

PDMS is an elastomer and conforms to the surface (containing nonplanar surface)
