This review article addresses the art and science of specific technique-the "Template Synthesis"(TS) used as a route in the development of nano-/micro materials and structures involving metals, non-metals, semiconductors, magnetic multilayered nano wires, conducting polymers, glasses, nano tubules, wires and whiskers etc . The recent past has witnessed keen interest being generated on the use of innovative technologies like TS in the production of nano materials' fabrication reported from various authors and from our lab. The strategy for embedding matter of interest within the etched pores or channels in the track-etch membranes as template is the material's placement through some suitable mechanism at the desired places viz., pores.
