1. 1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Emma Olofsson; [2023-06-22]
   Keywords : Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

   Abstract : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. READ MORE

3. 2. Separation of Nanoporous Silica Particles

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Frida Preuss; Julia Asp; Sofia Larsson; Stephanie Kylington; [2020]
   Keywords : Monodispersity; particle size distribution; density gradient; centrifugation; silica;

   Abstract : In this study a sample of particles in a size region of 0.05-10 μm were run through a centrifugation process with the ambition to make it monodisperse. The product requirements were stated as follows, particles within the size range of 2 to 3.8 μm should be isolated and separated from the sample with a D90/D10 < 1. READ MORE

4. 3. PREPARATION AND CHARACTERIZATION OF BOVINE MEAT AND MILK FACTOR VESICLES/PARTICLES & IDENTIFICATION OF MSBI1 REP INTERACTING PROTEINS

   University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

   Author : Farhana Manzoor; [2020]
   Keywords : Bovine meat and milk factors; multiple sclerosis; immunoprecipitation co-immunoprecipitation; protein dimers; mass spectrometry; immunodetection; cesium chloride density gradient centrifugation; sodium dodecyl sulfate-polyacrylamide gel electrophoresis; vesicle; particle; interaction partner; pull-down assay.;

   Abstract : Introduction: Bovine meat and milk factors (BMMF) frequently isolated from bovine meat and milk, are discussed as putative causative agents for breast, colon and possibly other cancers. The hypothesis was formulated based on earlier correlative studies indicating that BMMFs could indirectly trigger inflammation, accumulate mutational events via reactive oxygen and nitrogen species production which eventually provokes tumor formation.

5. 4. Development and evaluation of a pre-analytical device for liquid biopsy

   University essay from

   Author : Nicole Yacoub; [2018]
   Keywords : ;

   Abstract : In this project, a novel method to discover and monitor cancer was studied. Tumoureducated platelets (TEPs) have shown the ability to take up tumour-derived secretedmembrane vesicles, which contain tumour RNA. Therefore they are of great interestfor detecting cancer and could potentially work as biomarkers. READ MORE

6. 5. Towards monodisperse Silicon Nanocrystals: density gradient centrifugation applied on commercial gold nanoparticles

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Faraz Khavari; [2016]
   Keywords : Silicon Nanocrystals; density gradient centrifugation; gold nanoparticles;

   Abstract : The application of silicon nanocrystals as non-toxic bio-labels and downconverters requires their uniform size distribution in order to minimize the inhomogeneous broadening of the photoluminescence peak. In this thesis, we set the basis for their size-separation via the density-gradient centrifugation method. READ MORE
