   Sammanfattning : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. LÄS MER

3. 2. Biosensor Studies of Ligand Interactions with Structurally Flexible Enzymes : Applications for Antiviral Drug Development

   Författare :Matthis Geitmann; U. Helena Danielson; Marc H. V. van Regenmortel; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; SPR biosensor; HIV-1 reverse transcriptase; HCMV protease; interaction kinetics; drug discovery; non-nucleoside inhibitor; resistance; Biokemi; Biochemistry; Biokemi;

   Sammanfattning : The use of a surface plasmon biosensor fills a missing link in kinetic studies of enzymes, since it measures directly the interaction between biomolecules and allows determination of parameters that are determined only indirectly in activity assays. The present thesis deals with kinetic and dynamic aspects of ligand binding to two viral enzymes: the human cytomegalovirus (HCMV) protease and the human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT).
