Boron nitride-mediated semiconductor nanonetwork for an ultralow-power fibrous synaptic transistor and C-reactive protein sensing

Abstract

Bioinspired organic electrochemical transistor (OECT) with synaptic and sensing functions has shown great potential in wearable neuromorphic electronics and brain-like sensory systems. Despite the extraordinary progress in simulating neuromorphic functions,...

High-performance asymmetric electrode structured light-stimulated synaptic transistor for artificial neural networks

“…21,73,74 We therefore use eqn (2) to characterize the power consumption of a single light pulse synaptic event. Due to the excellent photosensitivity of As-LSST, the energy consumption of the synaptic device is about 2.14 × 10 −18 J when a light pulse of 100 ms duration is applied, which is close to the energy consumption per synaptic event in biological systems 75 (about 10 fJ). This provides a viable idea for designing low-power neuromorphic computing devices and also offers the possibility of optical synaptic devices that mimic the real eye and establish a connection between the brain's computational and visual systems.…”

Phosphorylcholine-Functionalized PEDOT-Gated Organic Electrochemical Transistor Devices for Ultra-Specific and Sensitive C-Reactive Protein Detection

“…Moreover, this PEDOT-PC-gated OECT device could detect the CRP molecules directly without the nonspecific binding blocking, as the PEDOT-PC gate electrode is intrinsically antifouling. However, the earlier electrochemical devices need BSA blocking to remove the surface nonspecific binding, thus, improving their detection specificity [ 4 , 11 , 14 ]. However, significant cross-reactivity was reported frequently for BSA blocking because of the bovine IgG contamination of commercial BSA [ 50 , 51 , 52 ].…”

“…Recently, a fibrous organic electrochemical transistor (OECT) was constructed from boron nitride (FBN)-mediated polypyrrole (PPy) neurofibers for CRP detection. The device’s high surface area and large transconductance guaranteed its low detection limit of 10 pg/mL with good reproducibility [ 14 ]. The OECT device’s high sensitivity and easy operation make it an attractive candidate for CRP detection [ 15 ].…”
