  1. 31. PLASMONIC NANOPORES: exploring new possibilities in DNA sensing and trapping

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Francesca Nicoli; [2013]
    Keywords : ;

    Abstract : In this work we explore the new DNA sensing and trapping possibilities offered by a plasmonic nanopore. This new device combines the sensing capability of solid state nanopores with the effects arising from the collective oscillation of electrons in gold nanoparticles (plasmons). READ MORE

  3. 32. Synthesis and Characterization of Gold Nanoparticles

    University essay from KTH/Fysik

    Author : Olof Hedkvist; [2013]
    Keywords : ;

    Abstract : This thesis is focused on the synthesis of three different shapes of gold nanoparticles; the gold nanosphere, the gold nanorod and the gold nanocube. These will be synthesized using wet chemistry methods and characterized using UV-Vis- NIR spectroscopy and dynamic light scattering. READ MORE

  4. 33. Development of an in vitro assay for analysis of cellular uptake of nanoparticles

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Lina Olsson; [2013]
    Keywords : Biology and Life Sciences;

    Abstract : Abstract MRI, magnetic resonance imaging, is used for disease detection such as assessing blood flow, detecting tumours and diagnosing many forms of cancer. Contrast agents are chemical substances that increase the MRI sensitivity. One class of contrast agents are the so called nanoparticulate contrast agents. READ MORE

  5. 34. Design and Characterization of Plasmonic Absorbers Based on Gold Nano-spheres

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Jin Dai; [2012]
    Keywords : ;

    Abstract : Noble-metal-based nanostructures can exhibit strong localized plasmon resonance at optical frequency, which leads to efficient plasmonic light absorbers. Such an artificially engineered absorber can have potential applications in sensing, cancer diagnosis and therapy, and photovoltaic cells etc. READ MORE

  6. 35. Neuron cell survival on positively charged surface bound gold nanoparticles over gold and silicon substrate

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Nabeel Aslam; [2011]
    Keywords : ;

    Abstract : The attachment of cells onto solid surfaces is a fundamental pedestal in the field of biosensors and biochips development. In this work we investigate the adhesion and survival of rat cortical neurons on positively charged surface. READ MORE
