2. 1. Asymmetric Cellular Microenvironments

   Author : Susanna Rydholm; Hjalmar Brismar; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Abstract : This thesis presents methods to combine 3D cell culture, microfluidics and gradients on a controlled cellular scale. 3D cultures in biological extracellular matrix gels or synthetic gels bridge the gap between organ-tissue cultures and traditional 2D cultures. READ MORE

4. 2. Through the Mirror : Perspectives of Brand Heritage

   Author : Sven Bergvall; Henrik Uggla; Rolf Solli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial engineering and economy; Industriell teknik och ekonomi;

   Abstract : The role of brands in contemporary society has in a fundamental way shifted the earlier balance of power in terms of consumers’ identity, in a sense creating a society where we are what we consume. This change has not only created enormous values centered around everyday brands, but also made brands into cultural objects interacting in a space earlier exclusive to such high-brow areas such as religion, science and the fine arts.

5. 3. Immunocytochemical visualization of cathepsin D during oxidative stress

   Author : Karin Roberg; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Cathepsin D is the major aspartic protease in lysosomes, and it is found in almost all animal cells. In the present studies, a pre-embedding immunocytochemical method was used to visualize cathepsin D in cultured cells. The protein can be detected at both light and electron microscopic levels by neutral-pH silver enhancement of ultrasmall (0. READ MORE

6. 4. MEMS Interfaces for Bioanalysis Systems

   Author : Thomas Frisk; Göran Stemme; Andreas Hierlemann; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfluidic interfacing; microfluidics; µTAS; sample transfer; biosensor; electronic nose; surface tension; quartz crystal microbalance; QCM; narcotics detection; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

   Abstract : This thesis deals with various aspects of using open microfluidic interfaces. Three specific areas of application are studied. The first is air-to-liquid interfacing in biosensors with possibilities for component inte­gration. A micromachined interface for airborne sample-to-liquid and droplet-to-liquid adsorption is discussed. READ MORE

   Abstract : Cancer represents a significant global public health challenge and ranks as the second mostcommon cause of death in the United States. The onset of cancer entails an initial phasewhere cells lose their polarity and disconnect from the normal basement membrane, allowingthem to form distinct three-dimensional (3D) configurations that interact with adjacent cellsand the surrounding microenvironment.
