|Membranes are barriers which regulate the transformation of information between cells. Biological membranes are inert barriers which plays an important role in the life of the cell. These biological membranes are mainly selectively permeable in nature which does not allow the crossing of atoms with certain charge, shape, size and chemical properties of the atom. This nature is essential for the effective separation of the cell or cell organelles.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
