This scheme illustrates EPF and perpendicular CoI inserted into the TNT. a EPF: CoI was transferred onto TNT in a semi dry transfer. The transfer unit was assembled from the bottom in the following order: (1) anode of a semi dry blotter; (2) 1× TGB-wetted filter paper; (3) TNT surface upward; (4) 6% Bis Tris gel; (5) TGB-wetted filter to which CoI was spotted at the titanium facing area; (6) cathode. b Scheme of perpendicular CoI inserted into the TNT
