  3. 3. Porphyrin Anchored DNA: Advances in DNA Nanotechnology

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jakob Woller; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Fysikalisk kemi; Physical chemistry; Biofysikalisk kemi; Biophysical chemistry;

    Sammanfattning : DNA nanotechnology has focused on the creation of complex structures using DNA as building blocks. DNA is an attractive construction material at the nano scale due to the self-assembly and specific base-pairing of the DNA bases, allowing the placement of functional groups with sub-nm precision.
