1. 1. Asymmetrical Flow Field-Flow Fractionation in the Application to Biological Macromolecules

   Författare :Cecilia Arfvidsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Bioteknik; Biotechnology; biotechnology; recombinant protein production; molecular weight; Escherichia coli; ribosomes; glutenin; asymmetrical flow field-flow fractionation; multiangle light scattering;

   Sammanfattning : Asymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. LÄS MER

3. 2. (Nano)materials for electrochemical sensing applications in different fields

   Författare :Nasrin Razmi; Omer Nur; Magnus Willander; Frank Bier; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrochemical bio sensors; Nanomaterials; AuNSs; α-Fe2O3 ZnO nanocomposite; RuO2-Nf pH electrodes; MIP technology;

   Sammanfattning : Health care and the medical industry, environmental monitoring and food sector are just a few examples of human’s major concerns. Design and analytical applications of (bio)sensors and sensing (nano)materials in these fields which have drawn tremendous attention by scientific community, require multidisciplinary knowledge in materials, transducers, and measurement methodologies.
