  1. 11. Nanoplasmonic Sensing using Metal Nanoparticles

    Författare :Erik Martinsson; Daniel Aili; Bo Liedberg; Karin Enander; Jakub Dostálek; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanoparticles; sensing; biosensors; refractive index sensing; plasmonics; nanoplasmonics;

    Sammanfattning : In our modern society, we are surrounded by numerous sensors, constantly feeding us information about our physical environment. From small, wearable sensors that monitor our physiological status to large satellites orbiting around the earth, detecting global changes. LÄS MER

  3. 12. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication

    Författare :Sarunas Petronis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofabrication; surface characterization; surface topography; surface chemical composition; marine biofouling; force-sensing substrates; microfabrication; surface-enhanced Raman spectroscopy; cell-surface interaction; biointerfaces; biomaterials;

    Sammanfattning : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. LÄS MER

  4. 13. Hydrogels of conjugated polyelectrolytes for biosensor and biochip applications

    Författare :Peter Åsberg; Karin D. Caldwell; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis describes the use of conjugated polyelectrolytes (CPEs) in biosensor devices. The method is based on non-covalent assembly of the biomolecule of interest and the CPE functioning as the reporter, in one case as a transducer, of biomolecular events. LÄS MER

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

    Författare :Jenny Carlsson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : 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. LÄS MER

  7. 15. Advances in analytical methodologies for studies of the platinum metallome in malignant cells exposed to cisplatin

    Författare :Yvonne Nygren; Erik Björn; Knut Irgum; Bente Gammelgaard; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Method development; Metallome; Inductively coupled plasma mass spectrometry; Electrospray ionization mass spectrometry; Liquid chromatography; Hyphenation; Organic modifier; Cisplatin; Platinum; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : The scientific progress about the important chemotherapeutic drug substance cisplatin (CDDP) and its function has often been rendered by data difficult to interpret, and still many questions about its mode of action remains to be clarified by the scientific community. However, studies of CDDP possess a high complexity due to; i) low intracellular concentration, ii) many potential biomolecule targets, iii) poor or unknown stability of the intact drug and its biomolecule adducts and iv) complex and varying sample matrices.
