Biotransducer is the acknowledgment transduction part of a biosensor framework. It comprises of two personally coupled parts; a bio-acknowledgment layer and a physicochemical transducer, which acting together believers a biochemical sign to an electronic or optical sign. The bio-acknowledgment layer commonly contains a chemical or another coupling protein, for example, immunizer. In any case, oligonucleotide groupings, sub-cell pieces, for example, organelles (for example mitochondria) and receptor conveying pieces (for example cell divider), single entire cells, little quantities of cells on engineered frameworks, or slight cuts of creature or plant tissues, may likewise contain the bio-acknowledgment layer. It gives the biosensor selectivity and particularity. The physicochemical transducer is regularly in personal and controlled contact with the acknowledgment layer. Because of the nearness and biochemical activity of the analyte (focus of premium), a physico-synthetic change is delivered inside the biorecognition layer that is estimated by the physicochemical transducer creating a sign that is proportionate to the convergence of the analyte. The physicochemical transducer might be electrochemical, optical, electronic, gravimetric, pyroelectric or piezoelectric. In light of the sort of biotransducer, biosensors can be delegated appeared to one side.

To increase the visibility and ease of use of open access scientific and scholarly journals top online publishing journals are indexed in different indexing and archiving services. Indexing provides easy access of the article online. The top online publishing journals publish articles which are cited as references by many authors in their work. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. Indexing provides easy access of the article online. The international journals are among the best open access journals in the world, set out to publish the most comprehensive, relevant and reliable information based on the current research and development on a variety of subjects. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal
