Label-Free, Impedance-Based Biosensor for Kidney Disease Biomarker Uromodulin

Label-Free, Impedance-Based Biosensor for Kidney Disease Biomarker Uromodulin

We demonstrate the development of a label-free, impedance-based biosensor by using a passivation layer of 50-nm tantalum pentoxide (Ta<sub>2</sub>O<sub>5</sub>) on interdigitated electrodes (IDE). This layer was fabricated by atomic layer deposition (ALD) and has a high diele...
