摘要:
Improved methods of forming a patterned self-assembled monolayer on a surface and derivative articles are provided. According to one method, an elastomeric stamp is deformed during and/or prior to using the stamp to print a self-assembled molecular monolayer on a surface. According to another method, during monolayer printing the surface is contacted with a liquid that is immiscible with the molecular monolayer-forming species to effect controlled reactive spreading of the monolayer on the surface. Methods of printing self-assembled molecular monolayers on nonplanar surfaces and derivative articles are provided, as are methods of etching surfaces patterned with self-assembled monolayers, including methods of etching silicon. Optical elements including flexible diffraction gratings, mirrors, and lenses are provided, as are methods for forming optical devices and other articles using lithographic molding. A method for controlling the shape of a liquid on the surface of an article is provided, involving applying the liquid to a self-assembled monolayer on the surface, and controlling the electrical potential of the surface.

摘要:
The invention provides a device for adhering cells in a specific and predetermined position, and associated methods. The device includes a plate defining a surface and a plurality of cytophilic islands that adhere cells, isolated by cytophobic regions to which cells do not adhere, contiguous with the cytophilic islands. The islands or the regions or both may be formed of a self-assembled monolayer (SAM).

摘要:
Methods and a device are provided for adhering cells in a specific and predetermined position. The device comprises a plate defining a surface and a plurality of cytophilic islands that adhere cells which are isolated by cytophobic regions to which cells do not adhere. The cytophobic regions can be wide enough such that less than 10 percent of the cells adhered to the cytophilic islands are allowed to form bridges across the cytophobic regions and contact each other. Further, the islands or the regions or both may be formed of a self-assembled monolayer (SAM). The methods are for forming a patterned surface for a population of cells and for selectively manipulating individual cells formed on the surface of the plate of the device. Furthermore, the device is used in immobilization of cells at a surface and for controlling shape of the cells.
