  1. 31. Isolation of nanoplastics in fish from the North Aegean sea

    University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Author : Isabella Gimskog; [2019]
    Keywords : nanoplastics; microplastics; Mediterranean; fish; isolation; applied biochemistry; tillämpad biokemi; Chemistry; Biology and Life Sciences; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : The breakdown of plastics in our oceans is one of our times biggest challenges. What happens when these plastics are broken down into pieces too small to see is still a mystery. Nanoplastics is a relatively new area of research and much more studies need to be done before we can get a perspective of how big the problem is. READ MORE

  3. 32. ADSORPTION OF STREPTAVIDIN ONTO POLYSTYRENE SURFACE

    University essay from Lunds universitet/Kemiska institutionen

    Author : Lina Le; [2018]
    Keywords : physical chemistry; fysikalisk kemi; Chemistry;

    Abstract : Microparticles of various sizes carrying different surface modifications have numerous technological and biomedical applications, for example to create a larger target for a molecular receptor by binding multiply ligands to the surface of the microparticle. The aim of the present work is to study how to most efficiently couple protein molecules to the surface of such microparticles. READ MORE

  4. 33. Real-Time Monitoring of Neurovascular Cells

    University essay from KTH/Mikro- och nanosystemteknik

    Author : Vladimir Banovic; [2018]
    Keywords : ;

    Abstract : Organs-on-a-chip devices are perfused cell culture systems aimed at creating the minimal functional unit of an organ - suchas the neurovascular unit (NVU) of the brain. NVU-on-a-chip platforms can provide an effective framework for studyingcentral nervous system physiology, disease etiology and provide a mean for drug development. READ MORE

  5. 34. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

    University essay from Umeå universitet/Institutionen för fysik

    Author : Thomas Moberg; [2018]
    Keywords : Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

    Abstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE

  6. 35. Enrichment of microparticles in droplets using acoustophoresis

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Klara Björnander Rahimi; [2018]
    Keywords : droplet microfluidics; acoustophoresis;

    Abstract : Acoustophoresis is a label free method where the acoustic radiation force is used to manipulate microparticles inside microfluidic channels. The magnitude of the force is dependent of several parameters, which include the density, speed of sound and size of the microparticles, as well as the amplitude of the pressure waves. READ MORE
