Metrohm DropSens is an Innovative Technology-Based Firm specialised in the design and manufacture of instruments for Electrochemistry Research, based in Oviedo, Spain. At Metrohm DropSens we develop screen-printed electrodes, based on thick-film hybrid technology, with the aim of providing researchers with a powerful tool for the development of electrochemical sensors of diverse nature: chemical, enzyme, immune and genosensors, etc. These sensors are aimed for important applications in the fields of clinical analysis, environmental and food control. Screen-printed electrodes offer a number of advantages versus conventional electrodes: they are suitable for working with microvolumes and for decentralized assays (point of care tests), etc.
