In this review article, we analyze recent progress in the application of liquid crystal-assisted advanced functional materials for sensing biological and chemical analytes. Multiple research groups demonstrate substantial interest in liquid crystal (LC) sensing platforms, generating an increasing number of scientific articles. We review trends in implementing LC sensing techniques and identify ...

The detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is considered as a problem of a great importance. Nowadays, however, most microwave techniques for biosensing are based on resonance structures, which can be used for measuring dielectric and conductivity properties of materials. In optics, special electrostatic-pla...

Over the past three decades effort has been devoted to exploit the field-effect mechanism in chemical and biological sensors, due to the potential of these devices to provide large arrays of sensors that are label-free, low-cost, disposable and can be easily integrated in portable instrumentation. Most of this work concerned the development of ion-sensitive field-effect transistors. More recent...

Recently determined structures of the oxygen-sensing heme domain of the bacterial protein FixL have revealed a new binding environment and signal transduction mechanism for heme; they have also provided new insights into the diverse 'PAS' domain superfamily.

Label-free sensors based on electrical, mechanical and optical transduction methods have potential applications in numerous areas of society, ranging from healthcare to environmental monitoring. Initial research in the field focused on the development and optimization of various sensor platforms fabricated from a single material system, such as fiber-based optical sensors and silicon nanowire-b...

Matrices and sensors resulting from inorganic, organic and biological nanocomposites are presented in this overview. The term nanocomposite designates a solid combination of a matrix and of nanodimensional phases differing in properties from the matrix due to dissimilarities in structure and chemistry. The nanoocomposites chosen for a wide variety of health and environment sensors consist of An...
