Abstract
Bioelectronic devices have been researched widely because of their potential applications, such as information storage devices, biosensors, diagnosis systems, organism-mimicking processing system cell chips, and neural-mimicking systems. Introducing biomolecules including proteins, DNA, and RNA on silicon-based substrates has shown the powerful potential for granting various functional properties to chips, including specific functional electronic properties. Until now, to extend and improve their properties and performance, organic and inorganic materials such as graphene and gold nanoparticles have been combined with biomolecules. In particular, bionanohybrid materials that are composed of biomolecules and other materials have been researched because they can perform core roles of information storage and signal processing in bioelectronic devices using the unique properties derived from biomolecules. This review discusses bioelectronic devices related to computation systems such as biomemory, biologic gates, and bioprocessors based on bionanohybrid materials with a selective overview of recent research. This review contains a new direction for the development of bioelectronic devices to develop biocomputation systems using biomolecules in the future.
Highlights
Bioelectronics is defined as the combined field of biology and electronics that has recently been greatly developed to overcome the current limitation of silicon-based electronics and biology-based engineering [1]
To overcome the limitations of biomolecules, innovative methods have been developed introducing nanoparticles to enhance the signal induced from biomolecules, combine biomolecules with carbon-based materials such as carbon nanotubes (CNT) or graphene for electrochemical signal increment and long-term stability using the biocompatibility of carbon-based materials, and the use of nanoscale-patterned chips as a platform for the extension of the functionality of bioelectronic devices such as by demonstrating nanoscale electronic functions and immobilizing different biomolecules independently at the nanometer scale to use these biomolecules simultaneously [17,18,19,20,21,22]
Various bionanohybrid materials that are capable of performing information storage, logical functions, and information processing have been developed for the development of bioelectronic devices including biomemory, biologic gates, and bioprocessors
Summary
Bioelectronics is defined as the combined field of biology and electronics that has recently been greatly developed to overcome the current limitation of silicon-based electronics and biology-based engineering [1]. To develop sophisticated and improved functional bioelectronic devices, various advanced materials have been studied and introduced to fabricate modern devices such as new functionalized structural graphene and two-dimensional materials [32,33,34] Through these efforts, various bionanohybrid materials that are capable of performing information storage, logical functions, and information processing have been developed for the development of bioelectronic devices including biomemory, biologic gates, and bioprocessors. Various bionanohybrid materials that are capable of performing information storage, logical functions, and information processing have been developed for the development of bioelectronic devices including biomemory, biologic gates, and bioprocessors Figure 1F.igBuiroee1le. cBtirooelneicctrodneivc idceevsicbeassbeadseodnonbiboinonaannoohhyybbrriiddmmataetreiarlisaltos tdoevdeelovpelboiopmbeimoomrye,mbioorloyg, ibc iologic gates, angdatbesi,oapnrdobcieospsroorcsesfsoorrsbfioorcboimocpomutpauttiaotnionsyssytsetemmss
