A mixture of electro-oxidized pyrene and pyrene NHS gave high performing biocathodes.

Using pyridine, the nitrogen-doped nanocarbon was synthesized by this method.

(a) Structure of chemical compounds. Number 1 was screened from the pilot library, and numbers 2-9 are its analogues. (b) Activities of each compound to inhibit the growth of Rs1002. Number and name of compounds used are number 1 (NPD252), 2 (NPD5838), 3 (NPD5839), 4 (NPD8268), 5 (NPD8269), 6 (NPD10580), 7 (NPD8265), 8 (NPD8264) and 9 (NPD5835). Overnight-cultured Rs1002 in 3 ml of BG medium was centrifuged, then bacterial density was adjusted to OD 660 = 0.1 with fresh BG medium. One hundred and fifty µl of Rs1002 suspension was added to each well of a 96-well microtitre plate. As a control treatment 0.5 µl of DMSO was added, and 0.5 µl of each compound (3 mg/ml, DMSO) was added to obtain a final concentration of 10 µg/ml. After incubation for 24 h at 27°C in microtitre plates, the absorbance at OD 600 was measured. The relative absorbance (OD 600) of the DMSO control was set to '1'. The results shown are means of three independent experiments with three replicates. Error bars represent standard deviations, and asterisks indicate that results are statistically significant compared to the DMSO control (*P<0.001). The final concentration of kanamycin (Km) was 50 µg/ml.
