This poster shows how Rheometry and GPC can be complementary tools for characterising the behaviour of polysaccharides in solution
|Rate and Mechanistic Investigation of Eu(OTf)2-Mediated Reduction of Graphene Oxide at Room Temperature|
Tufan Ghosh, Sandeepan Maity and Edamana Prasad
Eu(OTf)2 has been introduced as an efficient reagent for the reduction of graphene oxide. Details kinetic studies have been performed which suggests that, the method is more efficient compared to that of other commonly used reduction methods.

|Fluorescent Nanoprobes Confined in a Drop as a novel Sensing Platform for Detection of Metal Species at Trace Level|
Carlos Bendicho, Isabel Costas-Mora, Vanesa Romero, Isela Lavilla
In the last years, a great interest has arisen concerning the design and development of new optical probes for the sensitive and selective detection of chemical species making use of miniaturized and environmental friendly methods. In this sense, quantum dots (QDs) and metal nanoclusters (NCs) have important optical properties to be applied in analytical systems as fluorescent probes.
|Specificity of highly potent miRNA inhibitors|
Barbara Robertson, Andrew Dalby, Yuriy Fedorov, Jon Karpilow, Anastasia Khvorova1, Devin Leake, Annaleen Vermeulen
miRNA inhibitors are invaluable tools for elucidating the roles of miRNAs. However, potent inhibitors may also affect other miRNAs. To understand the potential cross-reactivity of miRNA inhibitors, various miRNA inhibitor designs were systematically tested. We demonstrate that mismatches both within and outside the seed region of the miRNA interfere with inhibition. Our findings indicate that features important for natural miRNA target recognition are also important for inhibitor specificity.
|Alternative miRNA design for therapeutic RNAi applications|
Anja van Brabant Smith, Barb Robertson, Annaleen Vermeulen, Christina Yamada, Angela Reynolds, Anastasia Khvorova, Devin Leake
For in vivo applications, the design of miRNA inhibitors and miRNA mimics must be optimized for stability and potency. However, stabilized miRNA mimic molecules can lose functionality compared to standard miRNA mimic molecules due, in part, to the activity of the stabilized passenger strand acting as a miRNA inhibitor. We discuss how mismatches affect the activity of the stabilized miRNA mimics, perhaps by generating a passenger strand that is less functional as an inhibitor molecule.
|Cas9 driven by an optimal promoter improves gene editing in eukaryotic cell lines when paired with synthetic crRNA and tracrRNA|
Amanda Haupt, Emily Anderson, Žaklina Strezoska, Hidevaldo Machado, Shawn McClelland, Maren Mayer, Adam Rocker, Annaleen Vermeulen, Amanda Birmingham, Melissa Kelley, Anja Smith
Presented here are results on the efficiency of using synthetic crRNA and tracrRNA to introduce gene editing events when co-transfected with a plasmid expressing Cas9. We explored the use of antibiotic and fluorescence activated cell sorting (FACS) methods for enrichment of cells that have undergone gene editing, and the use of multiple promoters to increase efficiency of gene editing with Cas9 and synthetic tracrRNA and crRNAs.
|Specificity and functionality of microRNA inhibitors|
Barbara Robertson, Andrew Dalby, Jon Karpilow, Anastasia Khvorova, Devin Leake and Annaleen Vermeulen
Our findings indicate that features important for natural miRNA target recognition also appear to be important for inhibitor specificity. Understanding the specificity of inhibitors allows for better interpretation of inhibitor activity in endogenous systems.
