"The thesis by Mercè Pacios exploits properties of carbon nanotubes to design novel nanodevices. The prominent electrochemical properties of carbon nanotubes are used to design diverse electrode configurations. In combination with the chemical properties and (bio)functionalization versatility, these materials prove to be very appropriate for the development of electrochemical biosensors. Furthermore, this work also evaluates the semiconductor character of carbon nanotubes (CNT) for sensor technology by using a field effect transistor configuration (FET). The CNT-FET device has been optimized for operating in liquid environments. These electrochemical and electronic CNT devices are highly promising for biomolecule sensing and for the monitoring of biological processes, which can in the future lead to applications for rapid and simple diagnostics in fields such as biotechnology, clinical and environmental research."

"The book deals with various consequences of major nuclear accidents, such as in 1986 in Chernobyl and in 2011 in Fukushima. This book provides a solid underpinning of the basic physical-chemistry and biogeochemistry of naturally occurring and anthrop radioactivity. It contributes to the development of international environmentally safe standards and economically reasonable standard regulations based on justified radiological, social and economical legislation concepts."

" As implied in the title of this textbook, Biosensors: From Electric Circuits toImmunosensors , we are going to learn both electric circuitry (in relation to conventionalsensors such as temperature sensors) and biosensors (such asantibody-based immunosensors), with equal emphasis on both. The overarchingaim is to build an antibody-based immunosensor from scratch. Before we begin thistextbook, let us defi ne two important terms: sensors and biosensors. Let us startwith sensors.Literally, a sensor is a device used to sense a physical variable, which includes,but is not limited to: temperature, strain, humidity, pressure, mass, light, andvoltage. To sense these variables, we need to convert them into a universal andeasily accessible signal— usually a voltage . This voltage signal changes continuouslywith time, and is directly proportional to a corresponding physical variable.A component responsible for this conversion is a transducer . The resulting voltagesignal is usually an analog signal.The analog voltage signal is usually transferred to a computer or a microprocessor,which recognizes digital signals only. An analog signal is converted into aseries of high and low voltages (i.e., binary numbers), such that a small fl uctuationin the analog signal (i.e., noise) does not affect the overall digital signal. Ananalog-to-digital converter (A/D converter) performs this conversion. Today,all-in-one type sensors have become very popular. They incorporate a transducer,an A/D converter, a microprocessor, and a small liquid crystal display (LCD) panel.The signal can also be sent to a computer’ s universal serial bus (USB) from an A/Dconverter."
