1. 6. Use of Biorecognition Elements or Their Mimics in New Flow Analysis Systems

   Författare :Bjarni Bjarnason; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; solid phase extraction; molecular imprinting; flow immunoassays; Capacitve biosensor; thermal biosensor; Analytisk kemi;

   Sammanfattning : We have evaluated capacitive and thermal transducers for recognition of bio- molecular interactions with different analytes. These assays were made in flow analysis systems because of the simplicity such methods provide. LÄS MER

3. 7. Affinity biosensors based on a capacitive transducer

   Författare :Christine Berggren; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self-assembled monolayers; capacitance; heavy metal ion; non-labeled; nucleic acid; DNA biosensor; Biosensor; immunosensor; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. LÄS MER

4. 8. Probing Biomolecular Recognition at the Single Molecule Level

   Författare :Anders Gunnarsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell membrane; TIRFM; liposome; time-of-flight secondary ion mass spectrometry; membrane receptor; single molecule; TOF-SIMS; molecular recognition; DNA; barcode; total internal reflection; multiplexing;

   Sammanfattning : Specific recognition between biomolecular partners contributes to a multitude of biochemical signaling within and between cells. The aim of this work has been to investigate the possibility to probe biomolecular recognition reactions at the smallest possible scale, the single molecule level. LÄS MER

5. 9. Advanced Nanofabrication for Novel Plasmonic Biosensors

   Författare :Francesco Mazzotta; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Photo diode; Localized surface plasmon resonance; Bioanalytical sensing; Nanopores.; Solar cell; Nanofabrication; Nanodisks; Nanoplasmonics; Biosensor;

   Sammanfattning : There is an increasing interest in the development of novel biosensors in the foreseeable future.The impact on society of diseases connected to the aging of population, for example infectiousdiseases, cancer and Alzheimer’s disease, has the potential of increasing the running costs ofwelfare over a sustainable threshold already within a few years.
