  1. 1. Controlled manipulation of microparticles utilizing magnetic and dielectrophoretic forces

    University dissertation from Eskilstuna : Mälardalen University

    Author : LarsErik Johansson; Sven Oscarsson; Leif Nyholm; [2010]
    Keywords : Dielectrophoresis; Magnetic beads; MEMS; Micro-particles; Micro-scale manipulation; Micro-system; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : This thesis presents some experimental work in the area of manipulation of microparticles. Manipulation of both magnetic and non magnetic beads as well as microorganisms are addressed. The work on magnetic bead manipulation is focused on controlled transport and release, on a micrometer level, of proteins bound to the bead surface. READ MORE

  3. 3. Light manipulation in micro and nano photonic materials and structures

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Zhihui Chen; Ying Fu; E. L. Ivchenko; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonic crystal; quantum dot; light-matter interaction;

    Abstract : Light manipulation is an important method to enhance the light-matter interactions in micro and nano photonic materials and structures by generating usefulelectric field components and increasing time and pathways of light propagationthrough the micro and nano materials and structures. For example, quantum wellinfrared photodetector (QWIP) cannot absorb normal incident radiation so thatthe generation of an electric field component which is parallel to the original incident direction is a necessity for the function of QWIP.
