Fig. 6. a) Isolation distance of the bare NiCr (n=3), AuNPs-coated (n=3) and AuNPs-PEDOT-coated (n=3) tetrodes; b) L-ratio values of the bare NiCr (n=3), AuNPs-coated (n=3) and AuNPs-PEDOT-coated (n=3) tetrodes. The levels of statistical significance were indicated as follows
*p<0.01. These values were calculated using a previously reported method [
