  1. 1. Robust and Biocompatible Bonding of Hybrid Microfluidic Devices Using Off-Stoichiometric Thiol-ene Thermosets

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Peter Harris; [2023]
    Nyckelord :OSTE; OSTE ; Microfluidics; Thermoset; Bonding; Thermoplastics; Biocompatibility; OSTE; OSTE ; Mikrofluidik; Härdplast; Binding; Termoplaster; Biokompatibilitet;

    Sammanfattning : Some of the major obstacles the microfluidics industry has yet to overcome in order to facilitate large scale manufacturing of devices are costly back-end processes. Among these, bonding presents some of the most obvious difficulties and is often associated with structural deformation and surface modification. LÄS MER

  3. 2. Fabrication and characterisation of a 3-layer aorta-on-a-chip

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Karolina Svensson; [2017]
    Nyckelord :Organ-on-a-chip; aorta-on-a-chip; PDMS; COC; microfabrication; APTES;

    Sammanfattning : Endothelial cells, EC, are the cell type closest to the blood stream in vessel walls. These cells can affect the origin of atherosclerosis, plaques clogging the vessels. The behaviour of EC is affected by neighbouring smooth muscle cells and shear stress from the blood flow. LÄS MER

    Sammanfattning : A spin-cast silicone membrane has been successfully bonded between two injection-molded microstructured plastic discs. This sandwich structure creates a useful platform for mass production of microfluidic systems, provided that the bonds are leakproof. LÄS MER

  5. 4. Micro-Structuring of New Materials Combined with Electronic Polymers for Interfaces with Cells

    Master-uppsats, Biomolekylär och Organisk Elektronik; Tekniska högskolan

    Författare :Alexander Vastesson; [2012]
    Nyckelord :Off-Stoichiometry Thiol-Ene; Polydimethylsiloxane; Microsystems; Nanosystems; Conducting polymers; HEP G2 cells; Cell viability; Soft lithography; DNA;

    Sammanfattning : Materials based on novel Off-Stoichiometry Thiol-Ene polymers, abbreviated OSTE, show promising properties as materials forlow cost and scalable manufacturing of micro- and nanosystems such as lab-on-chip devices. The OSTE materials have tunablemechanical properties, offer possibility for low temperature bonding to many surfaces via tunable surface chemistry, and can beused in soft lithography. LÄS MER

  7. 5. Worm-on-a-chip. Chemotaxis by nematodes in microfluidic systems

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Hans Bockgård; [2011]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A microfluidic chip was constructed and used for monitoring chemotaxis by nematodes. It was built up by an artificial dirt array made of glass, a perforated PDMS sheet and PMMA plate for fluidic connections. The device was held together by the pressure of clamps without any chemical bonding. LÄS MER
