20120028811 | DEVICE FOR RAPID IDENTIFICATION OF NUCLEIC ACIDS FOR BINDING TO SPECIFIC CHEMICAL TARGETS - The present invention relates to microfluidic chips and their use in SELEX. The microfluidic chip preferably includes a reaction chamber that contains a high surface area material that contains target. One preferred high surface area material is a sol-gel derived material. Methods of making the microfluidic chips are described herein, as are uses of these devices to select aptamers against the target. | 02-02-2012 |
