To evaluate the efficiency of the chemical optical technology, tests were carried out comparing the chemical optical sensors with conventional electrochemical systems (Figures 2A, 2B). Measurements of DO and CO2 were taken over a period of three weeks in a CHO cell culture. The optical sensor trended very closely with the standard electrochemical probes. Sensitivity of the optosensoric technology is higher than that of the conventional system.
PreSens’ optosensoric technology reviewed in this article can significantly contribute to improving the reproducibility and quality of cell cultivation and be applied in a broad range of scientific research.
