Filed:

Oct 1, 1999

Appl. No.:

09/410863

Inventors:

Sanjay L. Patil - Woodbury MN
Kurt J. Halverson - Lake Elmo MN
Robin E. Wright - Inver Grove Heights MN

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

C12Q 168

US Classification:

435 6, 4352872, 4352878, 4352887, 422 50, 422 681

Abstract:

The present invention provides high-density arrays including mask layers and methods of manufacturing the same. The arrays are formed on a polymeric substrate and include a mask layer. Various linking agents, linking agent coatings, and/or reactants may be provided on the mask layer. Where present, the linking agents and reactants preferably operate together to capture a desired analyte which can then be detected based on an electromagnetic signal, e. g. , fluorescence, that is emitted by the analyte in response to excitation energy incident on the array. With the mask layer in place, the signal-to-background ratio provided by the arrays can be increased.

Abstract:

In one aspect the invention provides an energy efficient polymerization method comprising irradiating a polymerizable composition and a photoinitiator with a source of essentially monochromatic radiation where the photoinitiator and the wavelength of the radiation source are selected such that the extinction coefficient of the photoinitiator at the peak wavelength of the source is greater than about 1000 M cm and such that the photoinitiator absorbs at least two percent of the actinic radiation incident on the coating. In another aspect the invention provides energy efficient methods of polymerizing polymerizable compositions and crosslinking crosslinkable compositions by irradiating the respective compositions with a low power source of essentially monochromatic radiation. The low power energy sources have an input power of less than about 10 W/cm. Articles made from the above methods, including polymer films having release coatings, adhesive coatings, hard coatings and the like thereon, also are provided.
