1. Amperometric Biosensors for Detection of Analytes in Cellular Models
Sammanfattning : Various biological problems such as disease mechanisms, drug development and toxicological studies motivated the introduction of cellular models that today also represent an alternative for reducing the use of animals in controversial medical and pharmaceutical experiments. Cells are complex matrices where several processes occur simultaneously. LÄS MER
2. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection
Sammanfattning : Amperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. LÄS MER
3. Biosensor-based Methods for Detection of Microcystins as Early Warning Systems
Sammanfattning : Cyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. LÄS MER
4. Enzymatic and Immunological Detection Principles for Environmental and Biological Applications
Sammanfattning : The aim of the thesis was to develop new analytical detection principles based on enzymatic and immunological reactions for sensitive, selective, cost-effective and high sample through-put detection devices. The thesis presents the basic elements and reaction paths necessary for the construction and development of enzyme based amperometric biosensors and immunoassays. LÄS MER
5. Amperometric biosensor-based microsystems for detecting analytes of biomedical importance
Sammanfattning : Monitoring in the biomedical field is rapidly emerging as the most important application area of miniaturized analytical devices. Diagnostics, disease monitoring, drug development, and medical research are important areas taking full advantage of the short response time, reduced sample consumption, low costs, and reduced power requirements of miniaturized analytical tools.
