20080293160 | DNA AND RNA CONFORMATIONAL SWITCHES AS SENSITIVE ELECTRONIC SENSORS OF ANALYTES - The electrical conductivity of DNA and other oligonucleotide constructs is dependent on its conformational state. Such a dependence may be harnessed for the electronic sensing of external analytes, for instance, adenosine or thrombin. Such a DNA sensor incorporates an analyte receptor, whose altered conformation in the presence of bound analyte switches the conformation, and hence, the conductive path between two oligonucleotide stems, such as double-helical DNA. Two distinct designs for such sensors are described that permit significant electrical conduction through a first or “detector” double-helical stem only in the presence of the bound analyte. In the first design, current flows through the analyte receptor itself whereas, in the second, current flows in a path adjacent to the receptor. The former design may be especially suitable for certain categories of analytes, including heterocycle-containing compounds such as adenosine, whereas the latter design should be generally applicable to the detection of any molecular analyte, large or small, such as the protein thrombin. Since analyte detection in these DNA sensors is electronic, the sensors may be used in rapid and automated chip-based detection of small molecules as well as of proteins and other macromolecules. | 11-27-2008 |

In one embodiment first and second channel plates are provided which may be sealed to a test chip in consecutive steps. Each channel plate includes microfluidic channels configured in a predetermined reagent distribution pattern. For example, the first channel plate may have a radial (linear) reagent distribution pattern and the second channel plate may have a spiral (curved) reagent distribution pattern, or vice versa. In one embodiment the first channel plate is connected to the test chip and at least one first reagent is distributed on the test chip in a first predetermined reagent pattern. The first reagent is then immobilized on the test chip. Next, the first channel plate is removed, the second channel plate is connected to the test chip and at least one second reagent is distributed on the test chip in a second predetermined reagent pattern. The first and second reagent patterns intersect to define a plurality of microarray test positions on the test chip. In one embodiment, the first reagent may comprise a plurality of separate probes each distributed to selected test position(s) of the microarray and the second reagent may comprise a plurality of test samples each distributed to selected test position(s) of the microarray. Positive or negative reactions between the probes (or other first reagent) and test samples (or other second reagent) may then be detected at the microarray test positions. For example, hybridization between selected nucleic acid probes and selected nucleic acid samples may be detected at particular test positions. The invention thus provides an efficient means to fabricate high density multi-probe, multi-sample microarrays. Preferably the test chips and channel plates are circular and centrifugal force is used to achieve fluid flow through the microfluidic channels, such as by rotating the MMA in a disc spinner. | 02-18-2010 |
