1. Electroactivity of conjugated polymers : A study of electrochemical doping and its applications
Sammanfattning : Electrochemical doping of conjugated polymers is a complex process, which forms the basis for both characterisation and applications of this class of materials. The high electron affinityof poly(quinoxaline vinylene)s and poly(pyridopyrazine)s, two types of polymers with potential use as electron acceptors in organic photodiodes, has been demonstrated with cyclic voltamrnetry.

2. From Macromolecular Design to Supramolecular Self-assembly
Sammanfattning : Advancements in drug delivery have enabled a wider array of prevention, control and treatment of diseases such as cancer. Drug delivery systems have the possibility of encapsulating drugs with low solubility, delivering them to specific locations in the body as well as obtaining a controlled and sustained drug release.

3. degradable electroactive polymers: Synthesis, Macromolecular architecture and scaffold design
Sammanfattning : Electrically conducting polymers induce specific cellular responses at the molecular level. One of the crucial limitations of the use of conducting polymers in tissue engineering is their inability to degrade. LÄS MER
4. Synthesis, characterization and molecular architecture of electroactive and degradable polymers
Sammanfattning : The third-generation biomaterials are designed to stimulate specific cellular responses at the molecular level. Recent studies have shown that electrical signals regulate cellular activities including cell adhesion, migration, proliferation and differentiation. LÄS MER
5. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges
Sammanfattning : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.
