Summary on the research advances in rapid biological detection technologies of E.coli in environment

This paper aims to introduce the authors' analysis and summarization of the research advances and the development trends of the various quick biological detection technologies, as well as principles and applications of molecular bio-technology and immunoassay. As is known, E.coli is a sanitary index for water purification, which plays an important role in water quality monitoring. However, traditional methods for monitoring E.coli still have some disadvantages, such as time-consuming, intricate procedures, and so on. To overcome such disadvantages, quick biological detection technology of E.coli, based on the principle of modern bio-technology, has been worked out promptly. So far, this bio-technical advance has become one of the highlights promoting the research work all over the world in the field. The present paper has also described the development trend of this technology. The paper's analysis and summary shows that the detection technology of E.coli, as a core of modern biological detection technology and the combination of modern instrumentation technologies, is promising with brilliant application prospect. This paper also indicates that the quick detection technology should be turned into a better technology with easier operation and simpler procedure, with higher sensitivity but lower cost.
