  3. 3. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Sarunas Petronis; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofabrication; surface characterization; surface topography; surface chemical composition; marine biofouling; force-sensing substrates; microfabrication; surface-enhanced Raman spectroscopy; cell-surface interaction; biointerfaces; biomaterials;

    Sammanfattning : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. LÄS MER

  4. 4. High-Aspect Ratio Nanofabrication for Hard X-Ray Zone Plates

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Karolis Parfeniukas; Ulrich Vogt; Hans Hertz; Anne Sakdinawat; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanofabrication; x-ray optics; zone plate; tungsten; silicon; reactive ion etching; metal-assisted chemical etching; Ronchi test; Physics; Fysik;

    Sammanfattning : Hard x-ray nanoimaging enables structural investigations of new materials for many applications. For high-resolution experiments, zone plate x-ray optics are commonly chosen.Two methods of zone plate nanofabrication are presented in this thesis.Zone plates are circular diffraction gratings with radially decreasing grating period.

  5. 5. Nanofabrication and Characterization for Applications in Biochemistry and Molecular Electronics

    Detta är en avhandling från Division of Solid State Physics, Lund University, P.O. Box 118, S-221 00 Lund, Sweden

    Författare :Jonas Tegenfeldt; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanofabrication; chemical functionalization; silanization; scanning force microscopy; AFM; lateral forces; image processing; admittance spectroscopy; Physics; biosensors; Biokemi; Fysicumarkivet A:1997:Tegenfeldt; Metabolism; Fysik; Biochemistry; localized etching;

    Sammanfattning : As man-made structures are made increasingly smaller it becomes possible to conduct measurements on single cells, molecules and eventually atoms. In this thesis prerequisites for making this possible are discussed. The underlying thought is that the structures should be used in biological and organic based applications. LÄS MER
