holographic sensor is a gadget that contains a multi dimensional image inserted in a keen material that identifies certain particles or metabolites. This recognition is typically a compound cooperation that is transduced as an adjustment in one of the properties of the holographic reflection (as in the Bragg reflector), either refractive file or separating between the holographic edges. The explicitness of the sensor can be constrained by including atoms in the polymer film that specifically connects with the particles of intrigue. A holographic sensor expects to incorporate the sensor part, the transducer and the showcase in one gadget for quick perusing of sub-atomic fixations situated in beautiful reflections or frequencies. Certain atoms that emulate biomolecule dynamic destinations or restricting locales can be fused into the polymer that shapes the holographic film so as to make the holographic sensors particular or potentially delicate to certain clinical significant particles like glucose, etc. The holographic sensors can be perused from a reasonable separation on the grounds that the transducer component is light that has been refracted and reflected by the holographic grinding installed in the sensor. Along these lines, they can be utilized in modern applications where non-contact with the sensor is required. Different applications for holographic sensors are hostile to falsifying

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
