Glucose Sensing by Time-Resolved Fluorescence of Sol-Gel Immobilized Glucose Oxidase

A monolithic silica gel matrix with entrapped glucose oxidase (GOD) was constructed as a bioactive element in an optical biosensor for glucose determination. Intrinsic fluorescence of free and immobilised GOD was investigated in the visible range in presence of different glucose concentrations by time-resolved spectroscopy with time-correlated single-photon counting detector. A three-exponential model was used for analysing the fluorescence transients. Fractional intensities and mean lifetime were shown to be sensitive to the enzymatic reaction and were used for obtaining calibration curve for glucose concentration determination. The sensing system proposed achieved high resolution (up to 0.17 mM) glucose determination with a detection range from 0.4 mM to 5 mM

The Campbells: lordship, literature and liminality

The Campbells have the potential to offer much to the theme of literature and borders, given that the kindred’s astonishing political success in the late medieval and early modern period depended heavily upon the ability to negotiate multiple frontiers: between Highlands and Lowlands; between Gaelic Scotland and Ireland, and, especially after the Reformation, with England and the matter of Britain. This paper will explore the literary dimension to Campbell expansionism, from the Book of the Dean of Lismore in the earlier sixteenth century, to poetry addressed to dukes of Argyll in the earlier eighteenth century. Particular attention will be paid to the literary proclivities of the household of the Campbells of Glenorchy on either side of what appears to be a major watershed in 1550; and to the agenda of the Campbell protégé John Carswell, first post-Reformation bishop of the Isles, and author of the first printed book in Gaelic in either Scotland or Ireland, Foirm na n-Urrnuidheadh (‘The Form of Prayers’), published at Edinburgh in 1567

Charlotte Brooke : A romantic metaphysical ?

Charlotte Brooke’s Reliques of Irish Poetry (1789) not only marks the beginning of Anglo-Irish poetry, but also the transition of Gaelic poetry from manuscript to print. With the inclusion of the Gaelic originals as well as her own translations, Ms Brooke’s work is an implicit rebuke to James Macpherson. Her English renderings, however, show every sign of having succumbed to the ‘booming charm’ of Macpherson’s prose and to late 18th century sentimental discourse in general. Though faithfully adhering to the content of the originals, Ms Brooke fails to capture the style and atmosphere of Gaelic verse. This paper analyses the consequences of Ms Brooke’s treatment in regard to a courtly love poem, Féach orm, a inghean Eóghain, a highly elaborate construct that owes much more to the metaphysical mode than to sentimental passion.Charlotte Brooke, une poésie “métaphysique” d’époque romantique ? Les Reliques of Irish Poetry (1789) de Charlotte Brooke marquent non seulement le début de la poésie anglo-irlandaise, mais aussi le passage de la poésie gaélique du support manuscrit à l’imprimé. En publiant les textes gaéliques originaux en regard de ses propres traductions, l’ouvrage de Ms Brooke était une dénonciation implicite du travail de James Macpherson. Cependant ses traductions anglaises manifestent sans cesse qu’elles ont sacrifié au charme conquérant de la prose de Macpherson, et au langage sentimental de la fin du XVIIIe siècle. Bien qu’elle suive fidèlement le contenu du texte original, Ms Brooke ne réussit pas à rendre le style et l’atmosphère de la poésie gaélique. L’auteur analyse les résultats du travail de Ms Brooke à propos d’un poème d’amour “courtois”, Féach orm, a inghean Eóghain, une composition très élaborée qui doit bien plus à l’inspiration “métaphysique” qu’à la passion.Mac Craith Mícheál.
