  1. 1. Silicon Nanopore Arrays : Fabrication and Applications for DNA Sensing

    Författare :Miao Zhang; Jan Linnros; Meni Wanunu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopore; array; electrochemical etching; DNA; optics; thermophoresis;

    Sammanfattning : Nanopore biomolecule sensing and sequencing has emerged as a simple but powerful tool for single molecule studies over the past two decades. By elec- trophoretically driving single molecules through a nanometer-sized pore, often sitting in an insulating membrane that separates two buffer solutions, ionic current blockades can be detected to reveal rich information of the molecules, such as DNA length, protein size and conformation, even nucleic acid se- quence.

  3. 2. Thermoplasmonic Effects in Microfluidic Systems

    Författare :Steven Jones; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermometry; thermoplasmonic bubbles; thermoplasmonics; plasmonics; thermophoresis;

    Sammanfattning : The field of plasmonics has enabled a plethora of scientific achievements over the past few decades. Such advances have been the result of the increased light-matter interaction that occurs over nanoscale dimensions facilitated by the localized plasmonic resonances supported by noble metal nanoparticles.

  4. 3. Mass Transport via Thermoplasmonics

    Författare :Steven Jones; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : When a metallic nanoparticle is illuminated with light under resonant conditions, the free electron gas oscillates in such a way that substantial amplification of the local electric field amplitude is achieved – this is known as a plasmonic resonance. This resonance enhances both the optical scattering as well as absorption. LÄS MER

  5. 4. Structural and Interaction Studies of the Human Protein Survivin

    Författare :Maria-Jose Garcia-Bonete; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; survivin; cell cycle; apoptosis; protein interactions; X-ray crystallography; Bayesian inference;

    Sammanfattning : Cell division and cell death (apoptosis) are two essential processes to maintain the specific number of cells in all multicellular organisms. In humans, the misregulation of these processes leads to severe diseases, such as cancer, and neurological, inflammatory or autoimmune diseases. LÄS MER

  7. 5. Measurements and simulations of thermoplasmonically induced Marangoni flows

    Författare :Pantea Dara; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microbubbles; optical force microscopy; Marangoni flow; thermoplasmonics; microfluidics;

    Sammanfattning : Particle transport in microfluidic environments is often dominated by slow diffusion near interfaces. However, by inducing localized fluid flow, it is possible to actively transport suspended nano-objects in confined spaces. LÄS MER
