Jeewanu
Jeewanu (Sanskrit for "particles of life") are synthetic chemical particles that possess cell-like structure and seem to have some functional properties; that is, they are a model of primitive cells, or protocells. It was first synthesised by Krishna Bahadur (20 January 1926 — 5 August 1994), an Indian chemist and his team in 1963. Using photochemical reaction, they produced coacervates, microscopic cell-like spheres from a mixture of simple organic and inorganic compounds. Bahadur named these particles 'Jeewanu' because they exhibited some of the basic properties of a cell, such as the presence of semipermeable membrane, amino acids, phospholipids and carbohydrates. Further, like living cells, they had several catalytic activities.〔 Jeewanu are cited as models of protocells for the origin of life,〔 〕〔 T. Gánti: (''The Principles of Life'' ), Oxford University Press (2003) ISBN 9780198507260 〕 and as artificial cells.〔
==Etymology==
Jeewanu is derived from Sanskrit ''jeewa'', meaning "life", and ''anu'', meaning the "smallest part of something", or the "indivisible". In contemporary Hindi, ''jeewanu'' also means unicellular organisms such as bacteria. Bahadur specifically used the term to represent the Indian philosophical tradition not only through the use of Sanskrit but also by inferring ideas on the origin of life from the Vedas. Bahadur, while employing the traditional Hindu philosophy, attempted to incorporate the advances in cell biology to the concept of abiogenesis.〔
