A biosensor can be defined as a device incorporating a biological sensing element connected to a transducer to convert an observed response into a measurable signal, whose magnitude is proportional to the concentration of a specific chemical or set of chemcials (Eggins 1996). According to the receptor type, biosensors can be classified as enzymatic biosensors, genosensors, immunosensors, etc. B...

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...

Usage nanoencapsulation technique to use bioactive compound for successful delivery. In addition, enables control flavour release during processing storage at desired time p...

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...

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...
