  5. 3. Surface analytical methods and multivariate data analysis applied to lectin panels

    Author : Jenny Carlsson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : In this thesis lectin panels on gold wafers were utilized to investigate sera from different mammals and meat juices from various species of animals. Lectins, which are a group of diverse, natural proteins recognize and bind to different carbohydrate structures present on the sera proteins and on the proteins in the different meat juices.

    Keywords : Molecular electronics; gas sensor; hybrid materials; place exchange; random telegraph signal;

    Abstract : Over the years many techniques have been proposed for the purpose of the formation of electrically conducting metal-molecule-metal junctions. One such technique utilizes gold-nanoparticles (AuNPs) that could assist in contacting small molecules between large gaps. READ MORE

  7. 5. Nanoparticles based molecular electronic devices with tunable molecular functionalization shell and gas sensing measurements

    Author : Omer Sher; Klaus Leifer; Khaled Saoud; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular electronics; gas sensor; hybrid devices; gold nanoparticles; organic molecules; secondary molecular functionalization process;

    Abstract : The idea to use molecules as a basic building block in electronic circuits was developed about 50 years ago when a molecular rectifier was developed, but it has been a challenge for this field to make its way to real-world application. Now, due to the advancement in technologies, the properties of single molecules are better understandable and controllable. READ MORE
