Semiconducting polymer nanospheres (SPNs) have been synthesized and encapsulated in phospholipid micelles by a solvent evaporation technique. Four different conjugated polymers were used, yielding aqueous dispersions of nanoparticles which emit across the visible spectrum. The synthesis was simple and easily reproducible, and the resultant nanoparticle(More)

This paper presents the results of a multimodal study of oral perception conducted with a set of material samples made from metals, polymers and woods, in which both the somatosensory and taste factors were examined. A multidimensional scaling analysis coupled with subjective attribute ratings was performed to assess these factors both qualitatively and(More)
The development of rapid, robust and high performance point-of-care diagnostics relies on the advancement and combination of various areas of research. We have developed an assay for the detection of multiple mRNA molecules that combines DNA nanotechnology with fluorescent nanomaterials. The core switching mechanism is toehold-mediated strand displacement.(More)
Aqueous dispersions of fluorescent semiconducting polymer nanospheres (SPNs) have been synthesised by two methods; miniemulsion and micellar encapsulation. The colloidal and optical stability of SPNs synthesised by these two methods has been compared in order to assess the potential of these fluorescent nanoparticles for use in biological applications. The(More)
