  1. 1. Polymerization of Zwitterionic Sulphobetaine Methacrylate and Modification of Contact Lens Substrate

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Tobias Ingverud; [2015]
    Keywords : Zwitterionic; Sulphobetaine; RAFT; ATRP; End-group-modification; Grafting-to; Contact lens; zwitterjonisk; RAFT; ATRP; ändgrupps modifiering; ympning-till; kontakt;

    Abstract : In this study, the zwitterionic monomer [2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) was polymerized in a controlled manner by reversible addition-fragmentation chain transfer (RAFT) polymerization. The SBMA was also polymerized by atom transfer radical polymerization (ATRP) but in a less controlled manner why ATRP was discarded for further use in the study. READ MORE

  3. 2. Intrinsically Functionalized Silk (Bombyx Mori)

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Gabriel Åberg; [2013]
    Keywords : Silk; Fibroin; Fibers; Coated fibers; Conductive Polymers; Flourescence; Silkworm; Bombyx Mori; Conjugated polymers;

    Abstract : The goal of the thesis is to incorporate materials with either fluorescent or conductive properties in silk fibers, by feeding silkworms with a diet containing these materials. To achieve this, one would have to breed (rear) silkworm from eggs into larvaes, then to feed the silkworms with this special diet containing fluorescent or conductive materials. READ MORE

  4. 3. Surface Modification of CdSe(ZnS) quantum dots for biomedical applications

    University essay from Institutionen för fysik, kemi och biologi

    Author : Ann Winzell; [2010]
    Keywords : Quantum dots; surface modification; XPS;

    Abstract : Quantum dots are inorganic nanocrystals of semiconductor metals that have unique light emitting properties. Due to their tunable and narrow emission profile, broad absorption spectra, resistance to photobleaching and high level of brightness they have emerged as inorganic fluorophores and numerous applicabilities for in vitro, in situ as well as in vivo studies are present.
