Abstract
The disclosure relates to a cell electrochemical sensor based on a 3D printing technology and application thereof and belongs to the technical field of electrochemical sensors and toxin detection. The cell electrochemical sensor of the disclosure is constructed based on a 3D printing technology, and the construction method comprises the following steps: precisely depositing a cell/carbon nanofiber/GelMA composite hydrogel on a working electrode of a screen-printed carbon electrode through 3D printing, and carrying out curing to obtain the cell electrochemical sensor. The disclosure constructs a cell electrochemical sensor with a three-dimensional cell growth environment and rapid and sensitive response. The cell electrochemical sensor constructed by the disclosure can be used for quickly and effectively determining the combined effect type and effect degree of deoxynivalenol family toxins by combining an electrochemical impedance method and a combination index method.
