Chemical arrays and method for their production

摘要

Methods, apparatus, and computer program products to form arrays (12) of polymers each having a pattern of features on a surface (11a) of a flexible elongated web (10). In a method polymers or their precursor units are applied at an application station to the surface. Multiple features (16) are covered at a reagent station (384) with a continuous volume of reagent which chemically reacts with precursors or the web (10). The flexible elongated web (10) is driven in a lengthwise direction through the application station. This sequence may be repeated as needed to form the arrays along the web. Also provided is a method preparing a surface of a flexible elongated web (10) to receive a biopolymer array (12). <IMAGE>
