Hetero‐Integration of Silicon Nanomembranes with 2D Materials for Bioresorbable, Wireless Neurochemical System

Abstract Although neurotransmitters are key substances closely related to evaluating degenerative brain diseases as well as regulating essential functions in the body, many research efforts have not been focused on direct observation of such biochemical messengers, rather on monitoring relatively associated physical, mechanical, and electrophysiological parameters. Here, a bioresorbable silicon‐based neurochemical analyzer incorporated with 2D transition metal dichalcogenides is introduced as a completely implantable brain‐integrated system that can wirelessly monitor time‐dynamic behaviors of dopamine and relevant parameters in a simultaneous mode. An extensive range of examinations of molybdenum/tungsten disulfide (MoS2/WS2) nanosheets and catalytic iron nanoparticles (Fe NPs) highlights the underlying mechanisms of strong chemical and target‐specific responses to the neurotransmitters…
