“…Due to versatile properties, such as biodegradability, biocompatibility, bioresorbability, optical transparency, and light weight, proteins, the most readily accessible biomolecules can be used as an attractive building blocks for the development of RRAM devices and endow these electronic memories with excellent performance and environmental benignity 31, 32. They have been both served as an active switching component of a passive substrate to construct two‐terminal RRAM devices with impressive ON/OFF ratios, ultralow density, low operating voltage, good degradability, and tunable‐resistive switching behavior 33, 34, 35, 36, 37, 38, 39…”

Phototunable biomaterial‐based resistive memory devices and understanding of their underlying switching mechanisms may pave a way toward new paradigm of smart and green electronics. Here, resistive switching behavior of photonic biomemory based on a novel structure of metal anode/carbon dots (CDs)‐silk protein/indium tin oxide is systematically investigated, with Al, Au, and Ag anodes as case studies. The charge trapping/detrapping and metal filaments formation/rupture are observed by in situ Kelvin probe force microscopy investigations and scanning electron microscopy and energy‐dispersive spectroscopy microanalysis, which demonstrates that the resistive switching behavior of Al, Au anode‐based device are related to the space‐charge‐limited‐conduction, while electrochemical metallization is the main mechanism for resistive transitions of Ag anode‐based devices. Incorporation of CDs with light‐adjustable charge trapping capacity is found to be responsible for phototunable resistive switching properties of CDs‐based resistive random access memory by performing the ultraviolet light illumination studies on as‐fabricated devices. The synergistic effect of photovoltaics and photogating can effectively enhance the internal electrical field to reduce the switching voltage. This demonstration provides a practical route for next‐generation biocompatible electronics.

In this letter, dissolvable and biodegradable resistive switching devices with cell structure of Mg/MgO/Mg were demonstrated. Electrical tests demonstrated good memory characteristics for nonvolatile application. The dissolution rate of Mg and MgO are characterized in deionized (DI) water and in phosphate-buffered saline (PBS) solution, with clear difference, 0.36 nm/s, 1.25 nm/s, 0.057 nm/s and 0.13 nm/s, respectively. The Mg/MgO/Mg devices on silk fibroin substrates are able to be completely dissolved as fast as 30 minutes while immersed in DI water. The Mg/MgO/Mg devices have excellent prospects for applications in transient electronics, secure memory systems, and implantable medical therapy devices.Index Terms-resistive switching memory, magnesium oxide, transient electronics.

The conversion of solar energy to sustainable energy sources is a significant field of study for the relief of the world's energy problems, and among the various strategies developed, semiconductor photocatalysts have received significant attention as a promising candidate due to their attractive efficiency, mild reaction conditions, and low cost. The enhancement of such photocatalysts with plasmonic materials, by virtue of the Schottky junction and localized surface plasma resonance phenomenon, could facilitate the rapid progress in enhancement of photocatalytic efficiency under visible light irradiation. To further improve photocatalytic efficiency, scientists look to nature for inspiration, culminating in the evolution of complex hierarchical structures in order to fully utilize the potential of solar energy. In the past decade, there has been significant progress in the development of bio‐inspired plasmonic photocatalysts, such as antireflective surfaces, 3D photonic structures, and branched structures. This review describes the state‐of‐the‐art bio‐inspired light manipulation approaches, as well as future challenges in solar energy harvesting by plasmonic photocatalysts.
