biosensor

(bī′ō-sĕn′sər, -sôr)
n.
1. A device that detects, records, and transmits information regarding a physiological change or process.
2. A device that uses biological materials, such as enzymes, to monitor the presence of various chemicals in a substance.

biosensor

(1) A sensor which collects data on a biologic or physiologic process—e.g., blood pressure, temperature, etc.
(2) A biomolecule or system—e.g., enzyme, receptor, antibody, organelle or cell—coupled to a microelectronic system or optical probe to enable rapid, accurate, low-level detection of substances in body fluids, water and air. Biosensors have been used to measure glucose, creatinine, ethanol, gamma globulin, lidocaine, nerve gases, penicillin, sodium ions, testosterone, theophylline, vitamin B12, and O2.

biosensor

(bī′ō-sen″sor″) [ bio- + sensor]
1. A device that senses and analyzes biological information, including temperature, heart rate, blood pressure, or the chemical composition of body fluids.
2. A device that incorporates some biologic agent (e.g. an enzyme) as a part of its sensing capability.

biosensor

a biological material such as an ENZYME, an ANTIBODY, a MICROORGANISM or other biological system, coupled to an appropriate transducing system, which act together to monitor a specific biochemical reaction and convert it into a measurable electrical signal. Biosensors may be used in health care, for example to measure specific METABOLITES in the body, and in the monitoring of pollutants in the environment. The enzyme glucose oxidase is used in the biosensor for monitoring GLUCOSE levels in the blood.

The device was based on environmentally resilient biosensor bacteria and miniaturized luminescence readout electronics that communicate with an external device wirelessly.
The alternative of high sensitivity, rapid and portable enzymatic biosensor kit is also expensive due to the cost of pure uricase (Attala et al., 2009).
Biotransducers, the second component of biosensors, convert the reactions from the bioreceptors into signals, such as an electrical current, a visual signal such as light or fluorescence, or a thermal signal such as a rise or drop in temperature.
In this context, we want to investigate the possibility to use electrogenerated polythiophene films in the construction of GOx-based biosensors. In particular, in the present work, we compare the behavior of two biosensors based on two different films: the first one was obtained from the commercially available 2,2'-bithiophene (2,2'-BT) and the second one from a bithiophene derivative designed and synthetized in our laboratory (4,4'-bBT), both reported in Scheme 1.
Long chain polynucleotides poly(dG) and poly(G) are widely prevalent in the human and other genomes at both DNA and RNA levels and are used in DNA-electrochemical biosensors, as models to determine the preferential interaction of drugs with G-rich segments of DNA.
