Immunoassays are powerful techniques for biomarker detection. Antigens, genes, and proteins are common targets in the development of biosensors. Additionally, sensors for lactate and glucose monitoring, biomarkers of oxidative stress are the subjects of much research. In the pharmaceutical industry, electrochemical biosensors based on enzyme inhibitors have garnered increasing interest in drug detection and analysis for their high sensitivity and low detection limits.

Screen printed electrodes from Metrohm DropSens can be modified with nanomaterials, mediators, and bioreceptors (antibodies, enzymes, DNA) to improve selectivity and affinity to the analyte to truly expand your clinical and immuno- applications with fast response times at a microliter scale.

Metrohm DropSens offers an array of screen printed and interdigitated electrodes. Not only can you custom design a new electrode, but modifications can also be made to existing electrodes. See below for some examples of common electrodes and modifications for clinical applications.
