    Abstract: The invention relates to methods and kits for determining the methylation status of a target nucleic acid molecule in a sample comprising (a) bisulfite treatment of the target nucleic acid, (b) amplifying the treated target nucleic acid with methylation-specific primers, (c) contacting the amplicons with a methylation-specific plasmonic nanoprobe and (d) determining the methylation status based on melting temperature Tm of the hybrid probe and the target nucleic acid. In particular, a plasmonic gold nanoparticle covalently coupled to a morpholino oligonucleotide probe. Also claimed are methods and kits for determining methylation status of the Septin 9 (SEPT9) gene promoter.

    Abstract: The invention relates to methods and kits for determining the presence of a mutation selected from the group consisting of 1555A>G and 1494C>T in human Mitochondrially Encoded 12S RNA (MTRNR1) gene in a sample from a subject, comprising, inter alia, amplifying at least part of the MTRNR1 gene and detecting the amplified DNA with a plasmonic gold nanoparticle covalently coupled to a morpholino oligonucleotide probe. The claimed method may be used for determining the risk of a subject to Aminoglycoside-induced hearing loss.

    Abstract: There is provided a polymeric microsphere comprising a thermally responsive monomer crosslinked with a functional group monomer, wherein the functional group monomer comprises at least one of a carboxylic acid functional group or an amine functional group. The thermally responsive monomer is preferably N-isopropylacrylamide (NIPAM), and the microspheres preferably comprise a coating of polymerized catecholamines (e.g. DOPA). There is also provided a method of preparing the polymeric microsphere and uses of the polymeric microsphere in culturing, harvesting, or expanding stem cells or stromal cells. Preferably, the cells, e.g. hMSCs (human mesenchymal stem/stromal cells), are expanded or harvested in serum-free and xeno-free medium.

    Abstract: The present application relates to methods of detecting a mutation in a target nucleic acid molecule. Two phosphorodiamidate morpholino oligomer probes that differ by at least one base are each covalently coupled to a nano article and hybridised to a target sequence. The melting temperature of the complexes between each of the two probes and the target nucleic acid are measured and compared to determine whether the sample contains a nucleic acid with the mutation. Further, the present invention relates to kits comprising a first and second conjugate as described herein and to the use of such kits for the detection of mutations in a target nucleic acid molecule or for assigning a genotype to a target nucleic acid molecule.
