Patterning of conducting polymers based on a random copolymer strategy: Toward the facile fabrication of nanosensors exclusively based on polymers

Fabrication of a nanosensor consisting exclusively of polymers with sensing performance superior to a microscale sensor is reported. The device is fabricated by a copolymer strategy combined with a lift-off process, which is capable of patterning a variety of conducting polymer species down to the nanometer scale (see Figure).
