From: A hybrid transistor with transcriptionally controlled computation and plasticity
a Eight OECTs on a microscope slide with PDMS sheets to form the OECT chambers, and b top view of a single OECT. c, d Representative fluorescence microscopy images of cells stained with LIVE/DEAD® BacLight™ cell assay with c live cells shown in green, and d dead cells shown in red. Background fluorescence signals from the gold electrodes (red channel) are also visible. Cells were supplemented with 20 mM lactate and no additional electron acceptor. e Colony forming units per mL (CFU/mL) were counted 24 h after OECTs operation with constant drain voltage VDS = −0.05 V and gate voltages VGS biased at -0.5 V, −0.2 V, 0.0 V, or 0.2 V. CFU/mL p value indicated = 0.0015. Cells were supplemented with 20 mM lactate and no additional electron acceptor. Data show the mean ± SD of 3 biological replicates, unpaired two-tailed Student’s t-tests were performed without adjustments for multiple comparisons, n.s. represents p > 0.05.
