“…Development of advanced organic bioelectronics has been a long-pursued goal of modern electronic technology because it enables the smooth connection between biological systems and semiconductor devices for detecting important physiological and pathological signals. [1][2][3][4] Organic electrochemical transistor (OECT) biosensor, a typical bioelectronic device, has recently attracted increasing attention due to its desirable properties in biosensing applications. [5,6] Such devices are potentiometric transducers and particularly sensitive to small interfacial potential change, leading to a remarkably amplified channel current.…”

Advanced organic bioelectronics enable smooth fusion between modern electronics and biological systems for better physiological monitoring and pathological examinations. Photon-regulated bioelectronics are especially desirable due to the non-contact impact, remote-control, and even selfpowered operation. However, few studies have addressed the advanced photon-enabled organic photoelectrochemical transistor (OPECT) biosensors capable of operation at zero gate bias. Here, on the basis of a hydrogel/graphene oxide hybrid (denoted as HGH), a multifunctional HGH-gated OPECT biosensor is presented, which is exemplified by Ca 2+ -triggered gelation on the CdS quantum dot (QD) photoelectrode linking with a sandwich immunoassay toward human IgG as the model target. Gelation of HGH on the CdS QD gate electrode can not only inhibit the interfacial mass transfer on the gate/ electrolyte interface, but also significantly block the light absorption of CdS QDs, leading to the corresponding change of the channel currents of OPECT device. At zero gate bias, this OPECT biosensor exhibits high gain in response to light and good analytical performance for human IgG with a detection limit of 50 fg mL -1 . Given the numerous intelligent hydrogel materials and their potential interactions with light, this work unveils a general platform for developing a new class of hydrogel-gated OPECT bioelectronics and beyond.

“…In particular, about 80% of the knowledge information in the brain is obtained through our eyes, so the recognition of these visual information is vital for human learning and memory. [43][44][45] In the visual system, the optical information is first captured by the photoreceptors of the human eye retina and then transmitted to the brain via optical nerves, as schematically shown in Fig. 5a.…”

“…Besides the three-terminal memristive devices discussed above, ionic liquid (IL) gating control has attracted wide attention from researchers due to its powerful charge control ability via an IL control gate. Researchers have discovered that, in addition to the effect of net charge under IL gate voltage particularly in oxides, there are often complicated ion insertion/extraction processes [233][234][235][236][237][238].…”

Neuromorphic computing systems employing artificial synapses and neurons are expected to overcome the limitations of the present von Neumann computing architecture in terms of efficiency and bandwidth limits. Traditional neuromorphic devices have used 3D bulk materials, and thus, the resulting device size is difficult to be further scaled down for high density integration, which is required for highly integrated parallel computing. The emergence of two-dimensional (2D) materials offers a promising solution, as evidenced by the surge of reported 2D materials functioning as neuromorphic devices for next-generation computing. In this review, we summarize the 2D materials and their heterostructures to be used for neuromorphic computing devices, which could be classified by the working mechanism and device geometry. Then, we survey neuromorphic device arrays and their applications including artificial visual, tactile, and auditory functions. Finally, we discuss the current challenges of 2D materials to achieve practical neuromorphic devices, providing a perspective on the improved device performance, and integration level of the system. This will deepen our understanding of 2D materials and their heterojunctions and provide a guide to design highly performing memristors. At the same time, the challenges encountered in the industry are discussed, which provides a guide for the development direction of memristors.
