Flexible Neural Interfaces Based on 3D PEDOT:PSS Micropillar Arrays (Adv. Mater. Interfaces 25/2022)

Flexible PEDOT:PSS Micropillar Arrays Flexible interfaces featuring 3D PEDOT:PSS micropillars are realized, showing tailored geometric area, surface properties and electrochemical characteristics as reported by Alice Lunghi, Michele Bianchi, Francesca Santoro, and co-workers in article number 2200709. Soft micropillars are shown to support the adhesion, growth and differentiation of SH-SY5Y cells and influence the direction of neurite outgrowth, fundamental requirements for high-performance neural interfaces.

Automated summary

Flexible PEDOT:PSS micropillar arrays were fabricated and their application in neural interfaces was investigated. The results demonstrated that these soft micropillars can support the adhesion, growth, and differentiation of cells, as well as influence the direction of neurite outgrowth.
