The present invention describes a method for identifying one or more of a plurality of sequences differing by one or more single base changes, insertions, deletions, or translocations in a plurality of target nucleotide sequences. The method includes a ligation phase, a capture phase, and a detection phase. The ligation phase utilizes a ligation detection reaction between one oligonucleotide probe, which has a target sequence-specific portion and an addressable array-specific portion, and a second oligonucleotide probe, having a target sequence-specific portion and a detectable label. After the ligation phase, the capture phase is carried out by hybridizing the ligated oligonucleotide probes to a solid support with an array of immobilized capture oligonucleotides at least some of which are complementary to the addressable array-specific portion. Following completion of the capture phase, a detection phase is carried out to detect the labels of ligated oligonucleotide probes hybridized to the solid support. The ligation phase can be preceded by an amplification process. The present invention also relates to a kit for practicing this method, a method of forming arrays on solid supports, and the supports themselves.

Methods and apparatus are provided for the fabrication of microscale, including micron and sub-micron scale, including nanoscale, devices. Electronic transport of movable component devices is utilized through a fluidic medium to effect transport to a desired target location on a substrate or motherboard. Forces include electrophoretic force, electroosmotic force, electrostatic force and/or dielectrophoretic force. In the preferred embodiment, free field electroosmotic forces are utilized either alone, or in conjunction with, other forces. These forces may be used singly or in combination, as well as in conjunction with yet other forces, such as fluidic forces, mechanical forces or thermal convective forces. Transport may be effected through the use of driving electrodes so as to transport the component device to yet other connection electrodes. In certain embodiments, the component devices may be attached to the target device using a solder reflow step.

A method for producing a capillary bead array comprises the steps of: dispensing beads into a liquid pool, outside a capillary, having a depth of almost the same length as the particle diameter of a bead; leveling the excessive beads by moving a leveling member which is in contact with and relatively capable of be moved to the liquid pool to remove excessive beads that the liquid pool cannot contain; aligning the beads in the liquid pool one- or two-dimensionally; bonding adjacent individual beads to each other; producing a structure having the plurality of beads bonded and aligned one- or two-dimensionally; removing the structure from the liquid pool; and disposing the structure in the capillary formed of soft resin, so that the beads comprising the plurality of beads retaining the one- or two-dimensional alignment can be introduced simultaneously into the capillary. This method reduces the time and cost necessary for bead array production and retains the bead alignment in the capillary, resulting in improved accuracy and reliability in experiments using the capillary array.

A microarray including hydrogel and a plurality of probes which are immobilized in discrete regions of the hydrogel, and a method of preparing the same are provided. When using the microarray and method, a solid substrate is not required and many biomolecules can be immobilized in a small volume, thereby obtaining high sensitivity. Since gel can be cut to obtain many pieces, many microarrays can be prepared at once.
