MnO₂ Nanoflower Integrated Optoelectronic Biointerfaces for Photostimulation of Neurons.

ABSTRACT: Optoelectronic biointerfaces have gained significant interest for wireless and electrical control of neurons. Three-dimentional (3D) pseudocapacitive nanomaterials with large surface areas and interconnected porous structures have great potential for optoelectronic biointerfaces that can fulfill the requirement of high electrode-electrolyte capacitance to effectively transduce light into stimulating ionic currents. In this study, the integration of 3D manganese dioxide (MnO₂ ) nanoflowers into flexible optoelectronic biointerfaces for safe and efficient photostimulation of neurons is demonstrated. MnO₂ nanoflowers are grown via chemical bath deposition on the return electrode, which has a MnO₂ seed layer deposited via cyclic voltammetry. They facilitate a h
