An impedimetric biosensor platform for bio-affinity assays was developed based on real-time, label-free electrochemical detection performed via direct interface to electronic digital data processing. The sensor array consists of 15 gold microelectrode pairs enclosed in three reaction chambers and bio-functionalized with specific DNA probes. The impedance change caused by specific target analyte...

Fibroblast growth factor receptor 3 (FGFR3) is a transmembrane tyrosine kinase protein in the fibroblast family, which plays key role many biological processes. Over-expression and activating mutations FGFR3 are frequent non-invasive bladder cancer, highlighting this as potential biomarker for recurrent cancer detection. Affimer reagents isolated against recombinant were assessed their affinity...

This study integrates the techniques of nanoelectroforming, hot-embossing, and electrochemical deposition to develop a disposable, low-cost, and high sensitivity nanostructure biosensor. A modified anodic aluminum oxide barrier-layer surface was used as the template for thin nickel film deposition. After etching the anodic aluminum oxide template off, a three-dimensional mold of the concave nan...
