  1. 21. Towards monodisperse Silicon Nanocrystals: density gradient centrifugation applied on commercial gold nanoparticles

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

    Author : Faraz Khavari; [2016]
    Keywords : Silicon Nanocrystals; density gradient centrifugation; gold nanoparticles;

    Abstract : The application of silicon nanocrystals as non-toxic bio-labels and downconverters requires their uniform size distribution in order to minimize the inhomogeneous broadening of the photoluminescence peak. In this thesis, we set the basis for their size-separation via the density-gradient centrifugation method. READ MORE

  3. 22. 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

  4. 23. Construction and development of a multifunctional measuring device for biomedical applications

    University essay from Umeå universitet/Institutionen för fysik

    Author : Tobias Nilsson; [2016]
    Keywords : lab-on-chip; bio-sensors;

    Abstract : Lab-on-a-chip technology is a rapidly growing research area. Joining together several disciplines, such as physics, biology and several instances of nanotechnologies. The aim of this research is mainly to produce chips that can do the same types of measurements as large lab equipment and measurement systems, but at a fraction of the size and cost. READ MORE

  5. 24. Towards the Development of the Dual Modal Contrast Agent for Computed Tomography and Ultrasound

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Hongjian Chen; [2016]
    Keywords : Computed tomography; Ultrasound; Hybrid contrast agents; Polyvinyl alcohol;

    Abstract : Nowadays hybrid imaging modalities are new trends in medical imaging. To improve the diagnostic outcome of hybrid imaging, multimodal contrast agents need to be developed. For example, hybrid contrast agents for computer tomography and ultrasound (CACTUS) are one of those desirable hybrid contrast agents for the modern medical imaging. READ MORE

  6. 25. Development of Wet Electrostatic Precipitator for Generation of Nanoparticle-Protein Solution

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Julia Adner; [2015]
    Keywords : WESP; Nanoparticle; bioligical identity; protein solution; Technology and Engineering;

    Abstract : To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. READ MORE
