“…This c-MWCNTs/ITO electrode surface has been functionalized with monoclonal aflatoxin-B1 antibodies (anti-AFB1) for the detection of aflatoxin-B1 using electrochemical technique. EM, X-ray diffraction, and Raman studies suggest successful synthesis of c-MWCNTs, and the FTIR studies reveal its carboxylic functionalized nature (Singh et al 2013).…”

Printed on acid-free paper PrefaceFood nanoscience and nanotechnology are emergent disciplines that have grown enormously in the last years due to the attractive properties that a number of foodrelated materials have at the nanoscale. Understanding basic principles of such properties constitutes the basis for building a robust knowledge base for developing products with improved and novel characteristics.Understanding fundamentals of food nanotechnology represents a huge challenge for universities, industries and the public sector. The complex mechanisms involved in the research, development, production and legislation of food nanoproducts are studied under multi-and inter-disciplinary scopes. Bearing this in mind, this book was conceived.This book aims to contribute to basic and applied knowledge on these fields by presenting recent advances in selected topics of food nanoscience and nanotechnology, and is divided into a total of 17 chapters. The first chapter presents an overview to the field; the following chapter discusses general techniques for studying foodrelated nanomaterials, followed by six chapters on specific techniques for preparing food nanomaterials while the next contribution on dispersed systems illustrates this important and vast field. The book continues with three chapters on food nanocomposites, including those for packing purposes, and two chapters on advanced aspects of food nan...

“…Carbon NMs can also serve as quenching species; coordinating single-stranded DNA labeled with a fluorophore to the surface of a C 60 cluster results in quenched PL from the fluorophore, while hybridization with complementary (analyte) DNA results in the release of the DNA/fluorophore complex from the C 60 and initiation of PL [104]. Carbon NMs have also been incorporated into sensors that rely on electrochemical feedback for analyte detection [105][106][107]. For example, employing a composite of carbon nanotubes and nanoscale zirconia on an indium-tin-oxide electrode, Das et al were able to demonstrate changes in electrochemical impedance arising from modifications of the surface [52].…”

There is increased interest towards the application of carbon based nanomaterials to biosensors since these can be used to quickly detect presence of the toxins in food, agricultural and environmental systems. The accurate, faster and early detection of food toxins is presently very important for ensuring safety and shelf life of agricultural commodities resulting from food contamination. The carbon materials (CNTs) and recently discovered graphene have been predicted to be promising candidates in the development of electrochemical biosensor owing to their exceptionally large surface area and interesting electrochemical properties. We focus on some of the recent results obtained in our laboratories pertaining to the development of biosensors based on multi-walled carbon nanotubes and graphene for mycotoxin(aflatoxin ) detection.
