Book excerpt: Graphene Based Biomolecular Electronic Devices outlines the fundamental concepts related to graphene and electronics, along with a description of various advanced and emerging applications of graphene-based bioelectronics. The book includes coverage of biosensors, energy storage devices such as biofuel cells, stretchable and flexible electronics, drug delivery systems, tissue engineering, and 3D printed graphene in bioelectronics. Taking an interdisciplinary approach, it explores the synergy produced due to charge transfer between biomolecules and graphene and will help the reader understand the promising bioelectronic applications of graphene-based devices. Graphene has applications in semiconductor electronics, replacing the use of traditional silicon-based devices due to its semi-metallic nature and tuneable energy band gap properties. The tuning of electron transfer with redox properties of biomolecules could potentially lead to the development of miniaturized bioelectronic devices. Thus, graphene, with its unique sensing characteristics, has emerged as an attractive material to produce biomolecular electronic devices. Explains advanced and emerging techniques for creating graphene-based bioelectronic devices Outlines the fundamental concepts of graphene-based bio-integrated systems Addresses the major challenges in creating graphene-based bioelectronic devices on a mass scale

Book Synopsis Graphene Electronic Device Based Biosensors and Chemical Sensors by : Shan Jiang

Download or read book Graphene Electronic Device Based Biosensors and Chemical Sensors written by Shan Jiang. This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional layered materials, such as graphene and MoS2, are emerging as an exciting material system for a new generation of atomically thin electronic devices. With their ultrahigh surface to volume ratio and excellent electrical properties, 2D-layered materials hold the promise for the construction of a generation of chemical and biological sensors with unprecedented sensitivity. In my PhD thesis, I mainly focus on graphene based electronic biosensors and chemical sensors. In the first part of my thesis, I demonstrated the fabrication of graphene nanomesh (GNM), which is a graphene thin film with a periodic array of holes punctuated in it. The periodic holes introduce long periphery active edges that provide a high density of functional groups (e.g. carboxylic groups) to allow for covalent grafting of specific receptor molecules for chemical and biosensor applications. After covalently functionalizing the GNM with glucose oxidase, I managed to make a novel electronic sensor which can detect glucose as well as pH change. In the following part of my thesis I demonstrate the fabrication of graphene-hemin conjugate for nitric oxide detection. The non-covalent functionalization through π-π stacking interaction allows reliable immobilization of hemin molecules on graphene without damaging the graphene lattice to ensure the highly sensitive and specific detection of nitric oxide. The graphene-hemin nitric oxide sensor is capable of real-time monitoring of nitric oxide concentrations, which is of central importance for probing the diverse roles of nitric oxide in neurotransmission, cardiovascular systems, and immune responses. Our studies demonstrate that the graphene-hemin sensors can respond rapidly to nitric oxide in physiological environments with sub-nanomolar sensitivity. Furthermore, in vitro studies show that the graphene-hemin sensors can be used for the detection of nitric oxide released from macrophage cells and endothelial cells, demonstrating their practical functionality in complex biological systems. In the last part of my thesis, I demonstrate the construction of few-layer molybdenum disulfide (MoS2) based field-effect transistor (FET) device for highly sensitive detection of Hg2+ ion in aquatic solutions. The detection of mercury in aquatic environment is of great importance because mercury is an environment pollutant with severe toxicity. High binding affinity between mercury and sulfur makes MoS2 a promising candidate for mercury sensing. Our studies demonstrate that MoS2 sensors can selectively respond to Hg2+ ion with a detection limit of 30 pM. This MoS2 FET based mercury sensor promises great potential for highly sensitive, label-free, low-cost, fast and non-aggressive detection of mercury in aquatic environment.
