Abstract: Molecules may be analyzed (e.g., sequencing of nucleic acid molecules) by tunneling recognition at a tunneling junction. Embodiments of the present invention may allow detecting individual nucleotides and the sequencing of a nucleic acid molecule using a tunneling junction. By labeling a specific nucleotide with a moiety, tunneling junctions may generate a signal with a suitable signal-to-noise ratio. The tunneling recognition uses a tunneling current that is mostly through the moiety rather than mostly through the nucleotide or a portion of the molecule of interest. Because a single nucleotide can be detected with a signal with a suitable signal-to-noise ratio resulting from the tunneling current passing through the moiety, embodiments of the present invention may allow for fast detection of nucleotides using a tunneling current.

Abstract: The present invention relates to a method for the manufacture of labeled oligonucleotide conjugates comprising the reaction of (a) an oligonucleotide having a labile protecting group bound to a terminal hydroxy group, and (b) a labeling compound, wherein said labile protecting group is partially or completely substituted by said labeling compound in a nucleophilic substitution reaction.

Abstract: The present invention is a microarray having a plurality of subarrays with a hydrophobic barrier that defines each subarray of the microarray, and a method for preparing such a microarray. The hydrophobic barrier is prepared using a microarray synthesis instrument, where NPPOC photoprotected and other hydrophobic group-bearing phosphoramidites are coupled to the microarray using light from a digital micromirror to direct formation of the hydrophobic barrier. The method utilizes hydrophobicity, a well-established property, of conventional phosphoramidite protecting groups for an entirely new application, the synthesis of hydrophobic barriers on microarrays.
