T-Ray Sensing and Imaging

Abstract Terahertz-ray (T-ray) wavelengths are long enough to pass through dry, nonpolar objects opaque at visible wavelengths, but short enough to be manipulated by optical components to form an image. Sensing in this band potentially provides advantages in a number of areas of interest to security and defense such as screening of personnel for hidden [...]

Microbial biosensors: A review

Abstract A microbial biosensor is an analytical device which integrates microorganism(s) with a physical transducer to generate a measurable signal proportional to the concentration of analytes. In recent years, a large number of microbial biosensors have been developed for environmental, food, and biomedical applications. Starting with the discussion of various sensing techniques commonly used in [...]

Biosensors for life quality: Design, development and applications

Abstract Biosensors, combining a selective biological recognition element and a sensitive transducer, are versatile analytical tools applied more and more in different fields, such as medicine, food quality and safety control, and environment pollution monitoring. They are expected to play an increasingly important role in the improvement of life quality. In this context, the present [...]

Micro- and nanotechnologies for intelligent and responsive biomaterial-based medical systems

Abstract …Combination of micro- and nano-fabricated systems with intelligent biomaterials that have the ability to sense and respond is a promising avenue for the development of better diagnostic and therapeutic medical systems. Micro- and nano-electromechanical systems (MEMs and NEMs) are now becoming a family of potentially powerful new technologies for drug delivery, diagnostic tools, and [...]

Anti-fouling bioactive surfaces

Abstract Bioactive surfaces refer to surfaces with immobilized bioactive molecules aimed specifically at promoting or supporting particular interactions. Such surfaces are of great importance for various biomedical and biomaterials applications. In the past, considerable effort has been made to create bioactive surfaces by forming specific biomolecule-modified surfaces on a non-biofouling “base” or “background”. Hydrophilic and [...]

Nano-Biosensor Development for Biomedical and Environmental Measurements

Abstract Nano biosensor development for biomedical and environmental measurements has been tried by research groups all over the world. Identifying and fabricating suitable nano-materials as enzyme immobilizing matrices to enhance characteristics of the sensor is the most important and difficult task of it. In this chapter we discuss about polypyrrole(PPy) nano-tube array grown on Alumina [...]
