  1. 1. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Henriksson; [2023]
    Keywords : Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Abstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

  3. 2. Interactions of the Human Recombinant Proteins JUNO and IZUMO1

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Emma Lundell; [2020]
    Keywords : male infertility; surphace plasmon resonance; protein interactions; gold nanoparticles; protein immobilization; manlig infertilitet; ytplasmonresonans; proteininteraktioner; guldnanopartiklar; proteinimmobilisering;

    Abstract : Det uppskattas att 15% av alla par världen över lider avinfertilitet. Ungefär hälften beror på manlig infertilitet och 40% av dessa fall kan ännu inte förklaras. Därmed är nuvarande metoder för att diagnostisera manlig infertilitet otillräckliga och ytterligare tekniker behövs. READ MORE

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

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Segervald; [2019]
    Keywords : AFM; NIL; SPR; SERS; nanohole; nanohole array; nanoimprint lithography; physical vapor deposition; plasma treatment; plasmonic; plasmons; surface plasmon resonance; localized surface plasmon resonance; metal enhanced fluoresence; surface enhanced raman spectroscopy; transmittance; nanoplasmonic; signal enhancement;

    Abstract : 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. READ MORE

  5. 4. Towards a tunable nanometer thick flat lens

    University essay from Uppsala universitet/Materialfysik

    Author : Hugo Laurell; Johan Hillborg; [2018]
    Keywords : Metamaterial; COMSOL; Fano resonances; Surface plasmon polariton; Localized surface plasmons; Nanophotonics;

    Abstract : This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. READ MORE

  6. 5. Biofunctionalization of a Fiber Optics-Based LSPR Sensor

    University essay from Linköpings universitet/Molekylär fysik

    Author : Karl Schenström; [2016]
    Keywords : Localized surface plasmon resonance; LSPR; nanoparticles; AuNP; AuNR; biosensor; refractive index; spectrophotometry; IgG; insulin; avidin;

    Abstract : When exposed to light, metal nanoparticles exhibit a phenomenon known as LSPR, Localized Surface Plasmon Resonance. The wavelengths at which LSPR occurs is very dependent on the refractive index of the surrounding medium. READ MORE
