Bias control based probabilistic bit device and method of making the same
The present application relates to the technical field of probabilistic bit device, and especially relates to a probabilistic bit device based on bias control and a preparation method thereof. The probabilistic bit device comprises an electrode pair and a probabilistic bit molecule, and the probabilistic bit molecule is connected between the electrode pair. The skeleton core is a symmetric or near-symmetric biferrocene group, and the two ferrocene units are equivalent redox active centers, and the redox potential is similar, which lays a foundation for state reversible switching and uniform charge delocalization. The ferrocene unit has excellent chemical stability and no thermal degradation problem; the intermediate bridging group can control the electronic coupling strength, which ensures the charge migration across the sites and avoids the coupling of the strong state merging. The results show that in the bias range of 260 mV-400 mV, the probabilistic bit molecule can be switched between the reduced state and the mixed valence state, and then the high and low state ratio of the device is changed, and finally a stable and controllable bias control type probabilistic bit device is constructed.

Nanoparticle-fibrous membrane composites are provided as tunable interfacial scaffolds for flexible chemical sensors and biosensors by assembling gold nanoparticles (Au NPs) in a fibrous membrane. The gold nanoparticles are functionalized with organic, polymeric and / or biological molecules. The fibrous membranes may include different filter papers, with one example featuring a multilayered fibrous membrane consisting of a cellulose nanofiber (CN) top layer, an electrospun polyacrylonitrile (PAN) nanofibrous midlayer (or alternate material), and a non-woven polyethylene terephthalate (PET) fibrous support layer, with the nanoparticles provided on the fibrous membranes through interparticle molecular / polymeric linkages and nanoparticle-nanofibrous interactions. Molecular linkers may be employed to tune hydrogen bonding and electrostatic and / or hydrophobic / hydrophilic interactions to provide sensor specificity to gases or liquids. The sensors act as chemiresistor-type sensors. A preferred implementation is a sweat sensor.
