   Sammanfattning : In this research new RF/microwave-based sensor solutions were developed for the monitoring of biological cells and human beings to obtain a better understanding of their activity or state in a quick, cheap, easy and continuous way. The effect of different substances on cell behaviour can be monitored by measuring the electrical environment where changes are observed as cells react to a stimulus. LÄS MER

3. 22. Novel Functionalized Nanopores for Plasmonic Sensing

   Författare :Bita Malekian; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; extinction spectra; nanopores; proteins; nanocaves; nanowells; surface plasmon resonance; nuclear pore complex; colloidal lithography; nanoplasmonic sensor; label-free sensing; electron beam lithography; plasmonic nanostructures;

   Sammanfattning : Nanoplasmonic sensors offer a label-free platform for real-time monitoring of biomolecular interactions by tracking changes in refractive index through optical spectroscopy. However, other surface sensitive techniques such as conventional surface plasmon resonance offer similar capabilities with equal or even better resolution in terms of surface coverage. LÄS MER

4. 23. Palladium-based Nanoplasmonics for Ultrafast and Deactivation-Resistant Hydrogen Detection

   Författare :Iwan Darmadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasmonic sensing; palladium hydride; palladium; polymer; localized surface plasmon resonance; Pd; nanoparticle; surfactant; hydrogen; palladium alloy; hydrogen sensor;

   Sammanfattning : In the hydrogen economy scenario, hHydrogen gas is ispotential to be the main energy carrier in the hydrogen economy scenario in the upcoming future. It receives much attention since the reaction with oxygen generates electricity and produces only clean waterhydrogen is attractive as energy carrier since the energy produced by its reaction with oxygen only producesleaves water as by-product.

5. 24. Electromagnetic Modeling and Sensitivity-Based Optimization of Medical Devices

   Författare :Oskar Talcoth; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; helical conductors; optimal measurements; thin-wire approximation; inverse problems; Convex optimization; pacemakers; design of experiments; MR safety; multi-scale; magnetic resonance imaging; magnetic tracking; optimal sensor placement;

   Sammanfattning : Electromagnetics is a fundamental part of biomedical engineering and modern healthcare due to the electromagnetic nature of several important processes in the human body and the interactions of electromagnetic fields with the human body. As a consequence, electromagnetics is exploited for diagnostic and therapeutic purposes by a multitude of medical devices. LÄS MER

7. 25. Membrane Induced Structure in Transmembrane Signaling Proteins and Peptides : Peptide–Lipid Interactions Studied by Spectroscopic Methods

   Författare :Sofia E. Unnerståle; Lena Mäler; Jason Schnell; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptide-lipid interaction; paddle domain; voltage gating; voltage sensor domain; micelle; phospholipid bicelle; solution structure; HAMP domain; nuclear magnetic resonance spectroscopy; circular dichroism spectroscopy; nonspecific interaction; Biophysics; biofysik;

   Sammanfattning : Biological membranes, defining the boundary of cells and eukaryotic organelles, are mainly composed of lipids and membrane proteins. Interactions between these lipids and proteins are needed to preserve the tight seal of the membrane, but also to induce structure for proper function in many membrane proteins. LÄS MER
