  • SAMPLE PRESENTATION DEVICE
    Publication number: 20110070659
    Abstract: The present invention relates to sample presentation devices useful in performing analytical measurements. These devices have been configured to enable various aspects of liquid handling such as: retention, storage, transport, concentration, positioning, and transfer. Additionally, these devices can enhance the detection and characterization of analytes. The sample presentation devices of the present invention are comprised of one or more substrates having a plurality of zones of differing wettability. Methods of analyzing samples using the sample presentation device of the invention, as well as methods of making the sample presentation devices are disclosed.
