Template induced patterning of surfaces and their reversible stabilization using phase transitions of the patterned material
First Claim
1. A composition which changes its dynamic state through non-covalent interaction with a template object comprising:
- imprinted amphiphilic molecules having hydrophobic tail groups and hydrophilic head groups which form a three-dimensional molecular imprinted surface at a solid/liquid interface;
wherein said three-dimensional molecular imprinted surface of said imprinted amphiphilic molecules is formed by bringing a template object in close contact with a non-imprinted surface of amphiphilic molecules to form the three-dimensional molecular imprinted surface; and
wherein said composition is reversibly switched between a fluid state and a solid state by variation of a physical parameter of said composition.

Abstract
A two-dimensional patterning of a three-dimensional surface by a template molecule (or object) involving non-covalent interactions between the template and the surface and the reversible fixation of the pattern by undergoing a phase transition in the patterned material. In this invention the surface provides a multitude of mobile functional groups (matrix) which are spatially arranged by the interaction with the template, the template selects and arranges only those groups out of a multitude of functional groups which allow for a maximum of interaction between the template and the surface. The resulting pattern is then stabilized by reducing the mobility of all functional groups present on the surface by undergoing a phase transition to a state of high surface viscosity. After separation of the template and the patterned surface, the pattern on the surface is used for recognition, separation or catalytic purposes.
