The present invention relates to a method and a device for producing saccharides and saccharide arrays. Said method is particularly useful for the synthesis of saccharides in parallel and of high-density saccharide arrays, such as microarrays, which are required for high-throughput screenings.

Defined sequence RNA synthesis by 3′.fwdarw.5′ direction is now well established and currently in use for synthesis and development of vast variety of therapeutic grade RNA and Si RNA etc. A number of such synthetic RNA requires a modification or labeling of 3′-end of an oligonucleotide. The synthesis of 3′-end modified RNA requiring lipophilic, long chain ligands or chromophores, using 3′.fwdarw.5′ synthesis methodology is challenging, requires corresponding solid support and generally results in low coupling efficiency and lower purity of the final oligonucleotide in general because of large amount of truncated sequences containing desired hydrophobic modification. We have approached this problem by developing reverse RNA monomer phosphoramidites for RNA synthesis in 5′.fwdarw.3′-direction. They lead to very clean oligonucleotide synthesis allowing for introduction of various modifications at the 3′-end.

The present invention relates to a sensor for an electronic tongue or nose for analysing a sample or detecting a target. The sensor comprises a support, on one surface of which a plurality of sensitive areas are located, each sensitive area comprising at least one receptor and being capable of transmitting a measurable signal generated by the interaction of at least one constituent of the sample or one target with at least one receptor. The sensor is characterised in that it comprises at least three sensitive areas that differ from one another in terms of their respective receptor compositions, at least one of the sensitive areas comprising a mixture of at least two different receptors, while the two other sensitive areas each comprise at least one of the two receptors.

Some embodiments described herein relate to a substrate with a surface comprising a silane or a silane derivative covalently attached to optionally substituted cycloalkene or optionally substituted heterocycloalkene for direct conjugation with a functionalized molecule of interest, such as a polymer, a hydrogel, an amino acid, a nucleoside, a nucleotide, a peptide, a polynucleotide, or a protein. In some embodiments, the silane or silane derivative contains optionally substituted norbornene or norbornene derivatives. Method for preparing a functionalized surface and the use in DNA sequencing and other diagnostic applications are also disclosed.

A microscope slide staining system has a chamber, a plurality of slide support elements, a plurality of spreading devices positionable in association with microscope slides supported on the slide support elements so the spreading devices define a gap between the spreading device and the microscope slide and so the spreading device and the microscope slide are movable relative to one another to spread at least one reagent on the microscope slide independent of the other spreading devices and microscope slides.
