Perspectives on the Future of Biosensor Technology

Comparison of various living organisms on the evolutionary scale further suggests that the emergence of intelligence might have something to do with the increasing complexity of “device architectures” (Marr 1982; Conrad 1990). As compared to digital computer architectures, it is apparent that the device architectures in living organisms allow for massively parallel, distributed information processing—a feature that digital computers strive to emulate with limited success. These features provide a road map; device intelligence lies in exploiting both physical and chemical interactions of component materials, in the use of organic materials as building blocks, and in the configuration of life-like architectures. However, this road map does not prescribe detailed implementations. Numerous obstacles need to be overcome. Thus, the design goal is clear, but what ought to be the optimal direction needs to be determined. From the very outset, molecular electronics research has been controversial and the approaches have frequently been disputed. For this reason, we should ask whether reverse-engineering biology is a viable approach.
Interfacial Catalysis at Oil/Water Interfaces
Published in Alexander G. Vdlkdv, Interfacial Catalysis, 2002
Molecular electronics uses molecular materials in which the molecules retain separate identities. As a result, the properties of such materials depend on the molecular arrangement, properties, and interactions. Theory seeks to guide the design and synthesis of effective molecular materials. It does so by analysis, interpretation, and prediction, leading to the development and evaluation of concepts, models, and techniques. The role of theory in treating molecular properties (mainly by molecular orbital methods) and arrangement (by electromagnetic or quantum-mechanical approaches) is of importance. When these factors are combined, the material properties can be treated more successfully in cases where the interactions are not essential in, e.g., in nonlinear optics as opposed to electronic transport properties.

Technological revolutions that occurred (e.g., Industrial Revolution of 19th century, technological revolution that was based on the first transfer variator (transistor, 1947), integrated circuits (ICs, 1958) [6, 7], solid-state circuits and semiconductors in 20th century] had a transformative impact in society, culture, and scientific community [8]. Scientific and technological transformations that were caused by ICs development were mainly caused by their components miniaturization, based on Moore’s law (1965). Miniaturization leads to circuits construction at the molecular or atomic level, which will open the way to molecular-electronics development.
Electronic excitation and electric field as switching mechanism for a single-molecule switch

The incredible progress in the power of electronic devices seen over the past decades, starting with the first working silicon transistor in 1954 [1], revolutionised almost all aspects of our life. The miniaturisation of integrated circuits allowed the creation of ever more complex electronic devices. It followed an apparent ‘law’ of doubling the number of transistors per area roughly every 18 months, dubbed Moore’s Law [2]. This development has now reached its physical limits [3], and alternative approaches to decrease the size of electronic components are being sought. One promising methodology is the use of molecular electronics, where single molecules act as switches or transistors.
Fault detection and analysis of bistable rotaxane molecular electronic switch - A simulation approach
Published in Journal of Experimental Nanoscience, 2018
According to existing literature CBPQT4+ ring on TTF is the Ground State Co Conformer and CBPQT4+ ring on DNP is the Metastable State Co Conformer [28]. Optimisation of molecular structure identifies the feasibility of using any molecule as a molecular electronic device. The higher molecular energy condition or distorted geometry (existence of a chemical bonding rather than the mechanical coupling between ring and dumbbell) condition corresponds to a faulty switch while lower energy with proper geometry corresponds to a true bistable rotaxane molecular switch.

The study of molecular electronics, or moletronics, is a promising way to the next generation of nanoscale integrated circuit and is a research field of sustained concern for several decades. it provides millions of potential molecular devices that may be self assembled, contain new performance, and even change the traditional way of information processing. Thousands of molecular devices have been investigated to find devices of suitable current–voltage characteristics for nanoscale circuits [1–5].
