Area of Science:

  • Materials Science
  • Bioengineering
  • Electrochemistry

Background:

  • Microbial bioelectronic devices require robust biotic-abiotic interfaces for optimal performance.
  • Existing interface modification methods often lack processability, patterning capabilities, or significant current enhancement.
  • Engineering biocompatibility, adhesion, and electron transfer at the interface remains a key challenge.

Purpose of the Study:

  • To develop a novel conductive polymer coating for enhanced microbial bioelectronic device performance.
  • To address limitations in current interface modification strategies.
  • To improve current densities and device functionality.

Main Methods:

  • A conductive polymer blend of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) crosslinked with poly(2-hydroxyethylacrylate) (PHEA) was synthesized.
  • A thin polydopamine (PDA) layer was used for adhesion to indium tin oxide (ITO) electrodes.
  • The coating's chemistry, morphology, and electronic properties were characterized. Implementation in microbial fuel cells, multiplexed devices, and sensors was demonstrated.

Main Results:

  • The novel coating achieved a 178-fold increase in current density with Shewanella oneidensis MR-1 compared to unmodified electrodes.
  • This current gain surpasses previously reported thin-film and 3D conductive polymer coatings.
  • The coating demonstrated successful implementation in microbial fuel cells, multiplexed bioelectronic devices, and microbial sensors.

Conclusions:

  • The developed conductive polymer coating significantly enhances current densities in microbial bioelectronic devices.
  • This simple yet effective interface modification strategy shows great promise for advancing the field.
  • The findings pave the way for improved microbial fuel cells, sensors, and other bioelectronic applications.
