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

    University essay from KTH/Tillämpad fysik

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

    Abstract : 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. READ MORE

  3. 2. Analysis of Stiffness Measurement Methods on Extracellular Vesicles

    University essay from KTH/Tillämpad fysik

    Author : Hanna Kylhammar; [2022]
    Keywords : Extracellular Vesicles; AFM; Atomic Force Microscopy; Fluorescent Microscopy; Extracellulära Vesiklar; AFM; Atomkraftsmikroskopi; Fluorescensmikroskopi;

    Abstract : Extracellular vesicles are important players in cell-to-cell communication and have the potential to be used as biomarkers for decease. The mechanical properties of extracellular vesicles is an active field of research, with new methods and models being developed. READ MORE

  4. 3. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    University essay from KTH/Ytbehandlingsteknik

    Author : Mohamed Hassan Abdi; [2021]
    Keywords : Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Abstract : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. READ MORE

  5. 4. A photodegradation study of conjugated polymers for organic solar cells by absorption spectroscopy and atomic force microscopy

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johansson André; [2021]
    Keywords : OSC; solar cells; active layer; polymer; degradation;

    Abstract : The effect of light exposure in ambient air on thin films made from an electron acceptor polymer poly{[N,N'-bis(2-octyldodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (N2200), an electron donor polymer Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] (TQ1) and their blends, has been studied using UV-vis spectroscopy and Atomic Force Microscopy (AFM). For solutions of TQ1, N2200 and blends, the linearity of the Beer-Lambert law for absorption spectroscopy has been verified. READ MORE

  6. 5. Self-assembly of Fatty Acids of Hair at the water-air interface

    University essay from KTH/Materialvetenskap

    Author : Marine Batista; [2020]
    Keywords : 18-MEA; 18-methyl eicosanoic acid; Langmuir films; Langmuir-Blodgett films; AFM; Self-assembly; Branched fatty acid; Curvature; 18-MEA; 18-methyleikosansyra; Langmuir monoskikt; Langmuir-Blodgett; AFM; Självassociering; Förgrenad fettsyra; Krökning;

    Abstract : 18-methyl eicosanoic acid (18-MEA), which is a branched fatty acid, is found at the outermost surface of mammalian hair with other straight-chain fatty acids such as palmitic acid and stearic acid. However, the precise role of 18-MEA is not yet completely understood. READ MORE
