1. 1. Photochemical Ligation Techniques for Carbohydrate Biosensors and Protein Interaction Studies

   Författare :Oscar Norberg; Olof Ramström; Stéphane Vincent; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Biosensors; CuAAC; Photochemistry; Thiol-ene yne; Perfluorophenylazide PFPA ; Lectins; Molecular recognition; Quartz crystal microbalance QCM ; Surface plasmon resonance SPR ;

   Sammanfattning : This thesis concerns the development of surface ligation techniques for the preparation of carbohydrate biosensors. Several methodologies were developed based on efficient photochemical insertion reactions which quickly functionalize polymeric materials, with either carbohydrates or functional groups such as alkynes or alkenes.
