摘要： These days, especially, the attention is increasing in high technology of sensors designed for various uses in biological matter, biomedicine, drug improvement, security, nutrition safety and ecological monitoring and measuring. The system of these sensors should typically be handy and economical, on condition that quick response with reliability, high sensitivity, and negligible false-reading counts are provided. Biosensors have a multi-disciplinary nature including: biology, chemistry, physics, instrumentation, electronics, optics, and market. The biosensors are detecting devices that combine a transducer with biologically sensitive and selective components. Biosensors can quantity combinations existing in the environment, chemical procedures, food and human body at inexpensive charge in comparison with traditional techniques. This editorial article briefly focuses on an overview of Biosensors, examples and providing a new vista of developments and applications.
