Biosensors based on the principle of Förster (or fluorescence) resonance energy transfer (FRET) have shed new light on the spatiotemporal dynamics of signaling molecules. Among them, intramolecular FRET biosensors have been increasingly used due to their high sensitivity and user-friendliness. Time-consuming optimizations by trial and error, however, obstructed the development of intramolecular...

Biosensors are the devices, which integrate the biological recognition element and a small transduction unit for the purpose of detecting various analytes. Biosensors are being developed for various applications such as quality control of food, agriculture, medical and pharmaceutical field, clinical assay and disease diagnostics. Recently, field of tissue engineering and cancer diagnostic provi...

Biosensors have experienced rapid, extensive development. To maintain the bioactivity of biomolecules and to give the electrochemical output signal required, appropriate bioimmobilization matrices for biomolecules are critical. In this review, we describe some advanced membrane materials (including hydrogels, sol-gel-derived organic-inorganic composites and lipid membranes), introduce electroch...

In this paper, we explore the acoustofluidic performance of zinc oxide (ZnO) thin-film surface acoustic wave (SAW) devices fabricated on flexible and bendable thin aluminum (Al) foils/sheets with thicknesses from 50 to 1500 ?m. Directional transport fluids along these flexible/bendable surfaces offers potential applications for next generation microfluidic systems, wearable biosensors soft robo...

background: whispering gallery modes (wgm) biosensors are ultrasensitive systems that can measure amount of adsorbed layer onto the micro-cavity surface. they have many applications including protein, peptide growth, dna and bacteria detection, molecular properties measurements and specific interaction and drug table recognitions due to their high sensitivity, compact size and label free sensin...

Surface plasmon resonance (SPR) biosensors are optical sensors exploiting special electromagnetic waves-surface plasmon-polaritons-to probe interactions between an analyte in solution and a biomolecular recognition element immobilized on the SPR sensor surface. Major application areas include detection of biological analytes and analysis of biomolecular interactions where SPR biosensors provide...

Biosensors are sensitive and can be used as disposable sensors for environmental control. These biosensors are based either on inhibition of acyl cholinesterases acetylcholinesterase or butyrylcholinesterase) by organophosphorus compounds or on inhibition of enzymes phosphatases (acid or alkaline) or on direct detection of organophosphorus compounds by organophosphorus hydrolase. The state-of-t...

Introduction: Wearable devices can provide new ways of sensing users’ contexts [1]. Since they can be worn, wearable devices tend to have a higher context recognition rate than existing personal mobile devices [2]. For that reason, wearable devices can provide new functions based on context recognition to improve the usability and efficiency of services [3]. Form factors and sensors are used to...
