Mikroarray-Traeger, Verfahren zu dessen Herstellung sowie dessen Verwendung

DE 10241409 A UPAB: 20040429 NOVELTY - Microarray carrier (A) comprises a substrate of polymer and/or copolymer having at least one surface with a static water contact angle ( theta 1), formed as an array of non-contacting regions with similar angle ( theta 2) where theta 1 is at least 10 deg. larger than theta 2. The regions of theta 2 carry optionally silanized silanol groups. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for methods for preparing (A). USE - (A) are used as DNA or protein chips, for performing binding assays in biological research, particularly for use in spotting processes where hydrophilic droplets of test solutions are deposited. ADVANTAGE - (A) are prepared from inexpensive starting materials and individual solutions can be applied to precise locations, as well formed spots. They are also more robust than standard glass substrates (virtually unbreakable), and the surface tension and chemical functionality can be controlled, independently of the environment
