  4. 3. Nano- and Micro-sized Molecularly Imprinted Polymer Particles on Solid Surfaces

    Författare :Tripta Kamra; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. LÄS MER

  5. 4. Energy Transduction and Sensory Signalling in Haloarchaea Structural Characterisation of the Photocycles of Bacteriorhodopsin and Sensory Rhodopsin II

    Författare :Karl Edman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic crystallography; proton pumping; Haloarchaea; structural mechanism; bacteriorhodopsin; sensory signalling; sensory rhodopsinII; retinal proteins;

    Sammanfattning : Archaeal rhodopsins belong a subfamily of heptahelical transmembrane proteins. All contain a buried retinal chromophore covalently bound to a conserved lysine residue in helix G via a protonated Schiff base. LÄS MER

  7. 5. Tailoring Conducting Polymer Interface for Sensing and Biosensing

    Författare :Lingyin Meng; Wing Cheung Mak; Anthony Turner; Daniel Filippini; Mikhail Vagin; Man Bock Gu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conducting polymer; Interface; Sensing; Biosensing; Bioelectronics;

    Sammanfattning : The routine measurement of significant physiological and biochemical parameters has become increasingly important for health monitoring especially in the cases of elderly people, infants, patients with chronic diseases, athletes and soldiers etc. Monitoring is used to assess both physical fitness level and for disease diagnosis and treatment.
