Použití elektrochemických biosenzorů na základě tištěných elektrod v praxi

Použití elektrochemických biosenzorů na základě tištěných elektrod v praxi je jedním z cílů Výzkumné skupiny biomarkerů. Ve spolupráci s Univerzitou Pardubice vyvinuli automatický přístroj, který tento sen přibližuje realitě. Mnohaletou práci na zařízení ocenil časopis Analytical Methods možností prezentovat výsledky na titulní stránce čísla 39.


Electrochemical detection systems that provide either quantitative or sample-to-answer information are promising for various analytical applications in the emerging field of point-of-care testing (POCT). Nevertheless, in mobile POC systems optical detection is currently more preferred compared to electrochemical detection due to the insufficient robustness of electrochemical detection approaches toward “real world” use. Over the last couple of decades, screen-printed electrodes (SPEs) have emerged as a simple and low-cost electrochemical detection platform. Here, we report, firstly and solely, a novel benchtop system for the processing of electrochemical methods on SPE platforms. Our solution prevents operator errors from occurring while processing and testing SPEs, achieves an automatic processing of more than 300 electrodes per day and enables comparative testing due to the presence of two simultaneous working channels; furthermore, the SPEs used can be stored in specially-designed cartridges. This novel device helps to overcome the major disadvantages in processing SPE technology, such as a low level of automation and issues with process repeatability, making this technology more efficient and enabling faster growth in industry.
