“…465,466 bR-FET-VCSEL monolithically integrated bio-photo-receivers and phototransceiver arrays have been successfully designed, fabricated, and characterized for standard communication applications. 467 Monolayers of bR could be more suitable for optoelectronic transport studies than multilayers because protein structure and orientation in monolayers is better defined. The transient photocurrent of bR monolayers in an aqueous environment has been measured in a photo-electrochemical cell where a bR monolayer was created at the interface between a transparent conductive electrode and an aqueous electrolyte gel.…”

We review the status of protein-based molecular electronics. First, we define and discuss fundamental concepts of electron transfer and transport in and across proteins and proposed mechanisms for these processes. We then describe the immobilization of proteins to solid-state surfaces in both nanoscale and macroscopic approaches, and highlight how different methodologies can alter protein electronic properties. Because immobilizing proteins while retaining biological activity is crucial to the successful development of bioelectronic devices, we discuss this process at length. We briefly discuss computational predictions and their connection to experimental results. We then summarize how the biological activity of immobilized proteins is beneficial for bioelectronic devices, and how conductance measurements can shed light on protein properties. Finally, we consider how the research to date could influence the development of future bioelectronic devices.

“…For example, several organic materials, as well as light sensitive biological systems were immobilized on inorganic carrier surfaces, like semiconducting nanoparticle aggregates, silicon nanorods, or transition metal‐oxides, metal, or carbon nanowires showing functional activities (for typical references see, e.g. 7–9). The key questions of researches these days are: new applications, reproducibility of the measurements, and stability – mainly that of the biological component.…”

Photosynthetic reaction center (RC) is one of the most important proteins, because it is Nature's solar battery converting light energy into chemical potential in the photosynthetic membrane assuring conditions for carbon reduction in cells. Although it is developed in nanometer scale, and is working in nanoscopic power, this is the protein that assures the energy input practically for the whole biosphere on Earth. The extremely large quantum yield of the primary charge separation (close to 100%) in the RC offers a big challenge to use it in nanodevices. Results of structural (AFM, EM), optical, and electro chemical investigations on RC bio-nanocomposite materials based on different carrier matrices (e.g., CNTs, ITO) will be presented.

“…Under variable optical power of 594 nm wavelength, the device showed a response of 175 V/W of optical power and a 16 dB dynamic range. Shin et al [50] showed an n-channel silicon MOSFET with PM on the extended Ti/Au gate electrode with a biasing capability. Using variable power 594 nm light a response of 4.7 mA/W was shown.…”

Molecular sensors and molecular electronics are a major component of a recent research area known as bionanotechnology, which merges biology with nanotechnology. This new class of biosensors and bioelectronics has been a subject of intense research over the past decade and has found application in a wide variety of fields. The unique characteristics of these biomolecular transduction systems has been utilized in applications ranging from solar cells and single-electron transistors (SETs) to fluorescent sensors capable of sensitive and selective detection of a wide variety of targets, both organic and inorganic. This review will discuss three major systems in the area of molecular sensors and electronics and their application in unique technological innovations. Firstly, the synthesis of optoelectric bacteriorhodopsin (bR) and its application in the field of molecular sensors and electronics will be discussed. Next, this article will discuss recent advances in the synthesis and application of semiconductor quantum dots (QDs). Finally, this article will conclude with a review of the new and exciting field of noble metal nanoclusters and their application in the creation of a new class of fluorescent sensors.
