DissertationDOI
Enzymatic amplification schemes towards electronic biosensing
TL;DR: Biosensors provide a powerful tool to detect the concentrations of various analytes and nowadays more and more cancer (and other) antigens are being identified, so it is essential to construct sensors which enable highly sensitive detection of such antigen molecules at very low concentrations.

Detection of Receptor-Ligand Interactions with an GHz Impedance Biosensor System
Development of biomedical applications of magnetic fluids and investigation of their physical properties
TL;DR: In this article, the magnetic and structural properties of cobalt nanoparticles in polysiloxane-based carrier fluids have been studied and the differences between the magnetic properties of silica-coated and non-silicacoated cobalt particles are discussed.

Use of polymer films in amperometric biosensors
TL;DR: The use of polymeric films as a medium to incorporate mediators, while an important function, is too vast for review here as mentioned in this paper, and the applications of polymer film-modified biosensors for selected analytical determinations are also presented.
Journal ArticleDOI
Novel immunoassay for the measurement of complexed prostate-specific antigen in serum
TL;DR: Both the serum concentration and the proportion of complexed PSA was substantially higher in patients with CaP compared with patients with benign prostate disease, and the cPSA assay may have utility in improving specificity in screening for prostate cancer.
Journal ArticleDOI
Screen-printed amperometric biosensors for the rapid measurement of L- and D-amino acids
TL;DR: The biosensor compares favourably with a standard photometric amino acid test and was used to monitor milk ageing effects and the assay is cheap, simple to perform and rapid, requiring only buffer-electrolyte and a small sample volume.
