A brief overview on simple and cost-effective surface patterning techniques developed in our research group is being presented.  These techniques are based on daily surface and interfacial phenomena to create ordered micro/nano structures.  Two of them will be emphasized; the Marangoni flow (MF) (e.g. �tears-of-wine�) based self-assembly and the fracture-induced formation (FIF) of ordered polydimethylsiloxane (PDMS) strips by peeling.  Various water droplet arrays created by MF can serve as templates for generating various polymeric structures, including PDMS stamps for contact printing applications (e.g. patterning proteins).  The ordered parallel strips formed by FIF can be applied to create polymeric films containing strips as well as to fabricate various mesh-like and check-board type patterns.  The resulting structures/patterns are currently being utilized as tissue engineering scaffolds for deep wound repairs and vascular grafts.
