  1. 1. Non-invasive monitoring of low molecular weight biomarkers relevant to skin inflammation and cancer

    Författare :Skaidre Jankovskaja; Tautgirdas Ruzgas; Johan Engblom; György Marko-Varga; Melinda Rezeli; Pawel Lukasz Urban; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tryptophan; Kynurenine; Phenylalanine; Tyrosine; Low molecular Weight Biomarkers; Non-Invasive; Skin Surface Sampling; Skin Permeability; Hydrogels; Prussian White; Health and society; Hälsa och samhälle;

    Sammanfattning : Development of skin inflammation and cancer in viable epidermis and dermis involve slow molecular weight (LMW) metabolites. We hypothesize that these LMW compounds can be collected on the surface of the skin and used for non-invasive diagnostics of skin disorders. LÄS MER

  3. 2. Bipolar electrochemistry for high throughput screening applications

    Författare :Sara Munktell; Fredrik Björefors; Maria Hahlin; Tautgirdas Ruzgas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bipolar electrochemistry; electrodeposition; corrosion; screening; gradients; recycling; gold nanoparticles; Scanning Droplet Cell; Hard x-ray photoelectron spectroscopy; pitting corrosion; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Bipolar electrochemistry is an interesting concept for high throughput screening techniques due to the ability to induce gradients in a range of materials and their properties, such as composition, particle size, or dopant levels, among many others. One of the key advantages of the method is the ability to test, create or modify materials without the need for a direct electrical connection. LÄS MER

  4. 3. Characterization of a Voltammetric Electronic Tongue

    Författare :John Olsson; Fredrik Winquis; Tautgirdas Ruzgas; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Electronic tongues were developed some ten years ago. These systems consist of an array of nonspecific sensors and a signal processing unit. The sensor signals are processed by pattern recognition methods which makes possible the extraction of specific properties from the sample. LÄS MER

  5. 4. Development of Wireless Biosensors Integrated into the Radio Frequency Antenna for Chipless and Battery-less Monitoring of Biological Reactions

    Författare :Atefeh Shafaat; Tautgirdas Ruzgas; Sebastian Björklund; Javier Sotres; Jessica Neilands; Daniel Aili; Malmö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Development of wireless sensors and biosensors is currently experiencing a rapid progress with a substantial focus directed toward highlighting their potential applications as non-invasive wearables, implants, and highly mobile point-of-care devices. Integration of wireless biosensors into the Internet of Things (IoT) is widely acknowledged as a technological advancement with the potential to significantly change daily life. LÄS MER

  7. 5. Electric Fields for Surface Design and Chemical Analysis

    Författare :Christian Ulrich; Fredrik Björefors; Ingemar Lundström; Tautgirdas Ruzgas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electric fields; Surface design; Chemical analysis; Bipolar electrodes; Impedance spectroscopy; Electrochemistry; Elektrokemi; Chemical physics; Kemisk fysik; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : This thesis deals with the use of electric fields for evaluation and control of chemical systems. An electric field can result in the flow of charge across an interface between a metal and a solution, by means of chemical reactions. This interplay between electricity and chemistry, i.e. LÄS MER
