Optically transparent electrodes to study living cells: A mini review

The use of electrochemical methods to study living systems, including cells, has been of interest to researchers for a long time. Thus, controlling the polarization of the electrode contacting living cells, one can influence, for example, their proliferation or the synthesis of specific proteins. Moreover, the electrochemical approach formed the basis of the biocompatibility improvement of the materials contacting with body tissues that use in carbon hemosorbents and implants development. It became possible to reach a fundamentally new level in the study of cell activity with the introduction of optically transparent electrodes in this area. The advantage of the using of optically transparent electrodes is the possibility of simultaneous analysis of living cells by electrochemical and microscopic methods. The use of such materials allowed approaching to the study of the influence of the electrode potential on adhesion activity and morphology of the different cell types (HeLa cells, endothelial cell, etc.) more detailed. There are a negligible number of publications in this area despite the advantages of the usage of optically transparent electrodes to study living cells. This mini-review is devoted to some aspects of the interaction of living cells with conductive materials and current advances in the use of optically transparent electrodes for the study of living cells, as well as the prospects for their use in cellular technologies.

Automated summary

Electrochemical methods have long been used in studying living systems, with the introduction of optically transparent electrodes allowing for a new level of cell activity research. The use of optically transparent electrodes enables simultaneous electrochemical and microscopic analysis of living cells, providing detailed insights into the influence of electrode potential on different cell types. Despite the advantages of using optically transparent electrodes, there is a lack of publications in this area.
