  1. 1. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

    Författare :Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

    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.

  2. 2. Geopolymer-based drug formulations for oral delivery of opioids

    Författare :Bing Cai; Susanne Bredenberg; Håkan Engqvist; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Opioid therapy for chronic pain generally use controlled release formulations to deliver analgesic drugs around-the-clock. Controlled release dosage forms can enlarge the therapeutic effect by controlling the rate and site of release. However, with high drug content, opioid formulations are easily targeted for non-medical use. LÄS MER

  3. 3. Extracellular matrix mimetic multi-functional scaffolds for tissue engineering and biomedical applications

    Författare :Ranjithkumar Ravichandran; Jaywant Phopase; Anthony Turner; Ann-Christine Albertsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Regeneration of functional tissues or complex organs via the combination of viable cells, biomimetic scaffolds, morphogenic factors, and external biophysical cues are the principle aims of Tissue Engineering (TE). TE relies on the use of artificial 3D scaffolds that can mimic the microenvironment of native tissue to harness the regenerative potential of cells. LÄS MER

    Sammanfattning : Today, the growing and aging population, and the rise of new global threats on human health puts an increasing demand on the healthcare system and calls for preventive actions. To make existing medical treatments more efficient and widely accessible and to prevent the emergence of new threats such as drug-resistant bacteria, improved diagnostic technologies are needed.

    Sammanfattning : In soft tissue defects that arise due to trauma, tumor resections and complex burns, a significant loss in adipose tissue remains a considerable challenge due to the insufficient regenerative capacity of the tissue. This thesis focuses on assessing cell-material interactions between degradable 3D polymer scaffolds with different designs and adipose tissue-derived stem cells. LÄS MER
