WO 200123092 A UPAB: 20010518 NOVELTY - A device for absorbing and releasing small amounts of liquid comprising: (1) a device for absorbing a substrate; (2) a dosing head containing a capillary for taking up and releasing very small amounts of liquid through a nozzle; and (3) a manipulating system for adjusting the relative positions of the nozzle and absorbing device so that the liquid is released when the nozzle is placed on the substrate, is new. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for absorbing and releasing very small amounts of liquid using the device. USE - For analyzing chemical and biological materials, especially haptenes, proteins, oligo- and polymeric nucleic acids, sugars, lipids and cells immobilized on the absorbing device which is especially a biochip. ADVANTAGE - Reduced amounts of test sample can be used.
