1. Dual-mode microelectrode array: incorporates electrophysiological (EP) sites modified with PtNPs/PEDOT:PSS and an electrochemical (EC) site for dopamine (DA) sensing modified with PtNPs/PEDOT:PSS/rGO/Nafion. 2. Dual-mode wireless microsystem: features dual-mode signal acquisition using EP and EC front-ends, dual-channel wireless transmission based on FPGA-ESP32 architecture, and coordinated data handling through the NeuroWireless 2.0 platform. 3. In vivo verification: enables simultaneous recording of spikes, LFPs, and DA-related electrochemical signals in the prelimbic (PrL) cortex during dexmedetomidine (Dex) administration. The 3 subsystems form a closed pipeline enabling end-to-end dual-mode neural monitoring.
