Bioinspired detection sensor based on functional nanostructures of S-proteins to target the folate receptors in breast cancer cells
Damiati, Samar; Peacock, Martin; Mhanna, Rami; Søpstad, Sindre; Sleytr, Uwe B; Schuster, Bernhard (Journal article; Peer reviewed, 2018)Development of biosensors requires a well-organized template to enhance the sensing specificity. Biological molecules that have the ability to self-assemble into ordered structures can be exploited to construct nanostructures ... -
Flexible electrochemical sensor platform
Søpstad, Sindre (Doctoral dissertations at the University of South-Eastern Norway;54, Doctoral thesis, 2019)Bringing an electroanalytical assay from the laboratory to the level of a commercially or clinically viable product often requires substantial cost, effort and time. While the real value may lie in the assay and sensor ... -
Hybrid electrochemical sensor platform for capsaicin determination using coarsely stepped cyclic squarewave voltammetry
Søpstad, Sindre; Imenes, Kristin; Johannessen, Erik Andrew (Peer reviewed; Journal article, 2019)A small, standalone electrochemical hybrid sensor platform, combining flexible electronics and screen-printed electrodes, is demonstrated in the determination of capsaicin through adsorptive stripping voltammetry. The ... -
Impedance-based sensor for potassium ions
Day, C; Søpstad, Sindre; Ma, H; Jiang, C; Nathan, Arokia; Elliott, Stephen R; Karet Frankl, FE; Hutter, Tanya (Journal article; Peer reviewed, 2018)A conductometric sensor for potassium ions in solution is presented. Interdigitated, planar gold electrodes were coated with a potassium-selective polymer membrane composed of a poly(vinyl chloride) matrix with about 65 wt% ... -
Long-term stability of screen-printed pseudo-reference electrodes for electrochemical biosensors
Søpstad, Sindre; Johannessen, Erik Andrew; Seland, Frode; Imenes, Kristin (Journal article; Peer reviewed, 2018)Pseudo reference electrodes forms an essential part of electrochemical transducers, where they are used to maintain a reference potential for the system. Yet, little is known about their long-term stability, and any drift ... -
Sensitivity Comparison of Macro-and Micro-Electrochemical Biosensors for Human Chorionic Gonadotropin (hCG) Biomarker Detection
Damiati, Samar; Haslam, Carrie; Søpstad, Sindre; Peacock, Martin; Whitley, Toby; Davey, Paul; Awan, Shakil A. (Peer reviewed; Journal article, 2019)Selectivity and sensitivity are important figures of merit in the design and optimization of electrochemical biosensors. The efficiency of a fabricated immunosensing surface can easily be influenced by several factors, ...
