1. 1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

   Master-uppsats, KTH/Fiber- och polymerteknologi

   Författare :Anna Wessén; [2023]
   Nyckelord :Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

   Sammanfattning : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

3. 2. Towards time-resolved cryo-EM of SARS-CoV-2 replication-transcription complex and Staphylococcus aureus DNA gyrase

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Anna Králová; [2023]
   Nyckelord :time-resolved cryo-EM; DNA gyrase; SARS-CoV-2; replication-transcription complex; protein purification;

   Sammanfattning : Time-resolved cryo-EM has already provided ground-breaking discoveries in various fields, including structural biology, biochemistry, and drug development. Compared to traditional structural biology methods where mostly stabilized conformations are reconstructed, the main advantage of time-resolved cryo-EM is its ability to capture dynamic processes in biological samples at near-atomic resolution, which allows for studying biological structures as they change and interact in real-time.

4. 3. Orbit-simulator for downstream processes

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Andreas Malmström; [2022]
   Nyckelord :Chemical engineering; Process simulation; Downstream processes; Orbit; Preparative chromatography; Python; Lumped Rate Models; Technology and Engineering;

   Sammanfattning : In an ever more digitilized society, the transition is palpable also in the pharmaceutical industry. The control system Orbit was developed at the department of chemical engineering at Lund University, to be able to automate downstream processes based on the ÄKTA-system. LÄS MER

5. 4. Development of MALS methods for exosome size analysis

   Master-uppsats, KTH/Kemi

   Författare :Terese Andersson; [2022]
   Nyckelord :Exosomes; Multiangle light scattering; MALS; extracellular vesicles; Exosomer; Multiangle light scattering; MALS; extracellulara vesiklar;

   Sammanfattning : Exosomer är extracellulära vesiklar i nanostorlek som frigörs från cellerna till den extracellulära matrisen. Exosomer är laddade med nukleinsyror, proteiner, och lipider, och fungerar som kommunikatorer mellan celler. Det har gjort dem mycket attraktiva for forskning inom terapi, diagnostik och transport av läkemedel. LÄS MER

7. 5. A Comparative Analysis of Per- andPolyfluoroalkyl Substances (PFAS) and ExtractableOrganofluorine (EOF) Using Solid PhaseExtraction-Weak Anion Exchange and Ion PairExtraction in SerumMarichal SalamehSpring 2021Independent project

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Marichal Salameh; [2021]
   Nyckelord :Extractable organofluorine EOF ; Per- and polyfluoroalkyl substances PFAS ; horse serum; human serum; ion pair extraction IPE ; solid phase extraction - weak anion exchange SPE-WAX ; liquid chromatography tandem mass spectrometry LC-MS MS ; combustion ion chromatography CIC ;

   Sammanfattning : Per- and polyfluorinated substances (PFAS) are compounds that consist of a carbon chainbackbone that is partially or entirely fluorinated, with an addition of a functional group. SomePFAS are known as persistent organic pollutants (POPs) and have therefore been drawing a lot ofattention as well as increased concerns. LÄS MER
