1. 1. Comparison and optimization of extracellular vesicle (EV) capturing on functional thin films for their molecular profiling

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Prattakorn Metem; [2023]
   Nyckelord :extracellular vesicle; plasmonic nanohole array; atomic force microscopy; fluorescence analysis; extracellulära vesiklar; nanohålsuppsättning; atomkraftsmikroskopi; fluorescensanalys;

   Sammanfattning : Extracellular vesicles (EVs) are lipid bilayer encapsulated nanoparticles which have emerged as an excellent source of biomarkers for multiple diseases, including cancer. However, they are highly heterogeneous in their molecular compositions which remains a major challenge hindering the utilization of their biomarker potential. LÄS MER

3. 2. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Sammanfattning : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. LÄS MER
