0D-carbon-quantum-dots/2D-MoS2 mixed-dimensional heterojunction transistor for emulating pulsatile photoelectric therapy of visual amnesic behaviors基于零维碳量子点/二维MoS2混合维异质结晶体管的 视觉失忆脉冲光电治疗模拟

Amnesia is a common clinical disorder manifested by the loss of recent memory as well as global impairment in the ability to acquire new memories, which seriously affects normal life activities of humans. At present, although herbal intervention, protein synthesis inhibition, and hormone replacement can prevent or reverse amnesia, these treatments are relatively expensive and inefficient. Here, an advanced photoelectric-synergistically pulsatile therapy is used to emulate the treatment of visual amnesic behaviors using a zero-dimensional (0D)-carbon-quantum-dots/2D-MoS2 mixed-dimensional heterojunction transistor. The photoelectric pulse could induce enough electrons to fill the trap states and accumulate at the mixed-dimensional interface. The significant biological behaviors, such as reconfigurable memorizing/forgetting behaviors and adjustable visual memory consolidation, are successfully realized in the device. More importantly, the photoelectric-synergistically pulsatile therapy for the effective treatment of visual amnesia is experimentally demonstrated for the first time. These results may provide promising opportunities for the development of medical memory diagnosis systems and human-machine realtime interactions, etc. [graphic not available: see fulltext]
