  1. 1. Concatemerization of Synthetic Oligonucleotides

    Författare :Lu Sun; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gel electrophoresis; DNA-binding; QCM-D; DNA concatemer; hybridization; DNA formation; self-assembly;

    Sammanfattning : DNA nanotechnology has become an important research field because of its advantages in high predictability and accuracy of base-paring recognition. For example, the DNA concatemer, one of the simplest DNA constructs in shape, has been used to enhance signals in biosensing. LÄS MER

  3. 2. Overstretching short DNA – Single-molecule force spectroscopy studies

    Författare :Niklas Bosaeus; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA stretching; mechanical properties of DNA; single molecule; optical tweezers; DNA structure;

    Sammanfattning : Structural deformation of DNA has a central role in many biological processes. It occurs, for example, during replication, transcription, and regulation of the activity of the genome. To understand these fundamental processes it is necessary to have a detailed knowledge of the mechanical properties of DNA. LÄS MER

    Sammanfattning : .... LÄS MER

  5. 4. Theory of van der Waals bonding: from bulk materials to biomolecules

    Författare :Elisa Londero; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alkanes; extended systems; DNA; band structure; van der Waals Density Functional vdW-DF ; exchange functionals; Density Functional Theory; non-local correlation; layered oxides;

    Sammanfattning : Sparse matter is abundant in Nature.It encompasses systems characterized by an intrinsic low density of electrons in sizeable regions, where the van der Waals forces contribute considerably to cohesion.Given the length scale of the problem, a prediction of these materials requires appropriate tools within a quantum-mechanical framework.

  7. 5. Modeling of dielectrophoresis in micro and nano systems

    Författare :Yuan Lin; Gustav Amberg; Hywel Morgan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dielectrophoresis; micro particle; molecular dynamics; single-walled carbon nanotubes; hydrodynamics; particle-particle interaction; superimposed; multi-step; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : This thesis presents models and simulations of dielectrophoretic separation of micro and nano particles. The fluid dynamics involved and the dielectric properties of water inside single-walled carbon nanotube are studied as well. LÄS MER
