  1. 1. Closed-loop strategy for valorization of starch : From starch to functionalized starch biomaterials and bioplastics

    Författare :Duo Wu; Minna Hakkarainen; Elisabetta Ranucci; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Nano-graphene oxide; Microwave; Valorization; Scaffold; Biomineralization; Bioplastics; Compatibilizer; Plasticizer; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The desire to utilize renewable resources and avoid wastes drives us to develop new concepts for material design. Non-edible starch feedstocks and starch bioplastic wastes were previously considered useless. LÄS MER

  3. 2. Mesoporous Implants for Localized Controlled Drug Delivery

    Författare :Johan Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; release kinetics; mesoporous titania; biomineralization; drug delivery; Biomedical implants; osseointegration; osteoporosis drugs; nanotopography; stem cells homing;

    Sammanfattning : The use of bone-anchored implants is today a routine treatment for patients with normal regenerative capacity. However, there is an ongoing development within implant research to improve the osseointegration of implants. LÄS MER

  4. 3. Novel non-collagenous modulators of biomineralization in bone and dentin

    Författare :Eszter Somogyi-Ganss; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Calreticulin; nucleobindin; prothrombin; biomineralization; osteogenesis; dentinogenesis;

    Sammanfattning : The formation of mineralized tissues such as bones and teeth is governed on many levels by molecular, genetic, and cellular events to culminate in terminally differentiated cells that secrete a specialized organic matrix, which is later mineralized through the coordinated deposition of calcium phosphate crystals. The formation of this hard tissue phase is tightly regulated by components of the extracellular matrix (ECM), since deviations from this equilibrium result in prevalent, debilitating health problems such as arthritis, vascular calcification, periodontal disease and osteoporosis.

  5. 4. Studies on three matrix molecules in bone and dentin

    Författare :Ulrika Petersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Osteoadherin OSAD ; Nucleobindin Nuc ; Calreticulin CRT ; biomineralization; osteogenesis; dentinogenesis;

    Sammanfattning : The biomineralization of bone and dentin is a complex and dynamic process, involving the formation of an organic framework in which mineral crystals are deposited. The noncollagenous proteins (NCPs) of the organic phase play a central role in the extracellular matrix (ECM) organization and mineralization regulation. LÄS MER

  7. 5. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Författare :Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER
