ABSTRACT

ABSTRACT: This article reviews about naturally occurring conducting polymer, Melanin. In this paper detailed explanation was included conducting polymers that have been developed with wide range of properties and potential applications due to their chemical, mechanical, optical and electrical properties such as sensors, electromechanical devices, batteries and electro chemical cell. In addition ist was also describer about Melanins that is serve as a free radical scavengers, antioxidants and photoconductors. However, some researchers have shown that cells containing small amount of melanin are more susceptible to damage from irradiation. This observation has been linked to iron content of melanin, in that when melanin is saturated with transition metal ions like iron it may actually produce free radicals and therefore accelerates cell death rather than protecting it. Therefore it is advisable to protect the melanin pigment from saturation with such transition metal ions (abstact).
