Popis: Nerve gases are dangerous agents of chemical warfare and mass destruction which can cause irreversible damage to the nervous system within seconds and are fatal if exposure occurs for even a few minutes. The nerve gases or agents were developed during the second world war and thereafter were banned from production. However, despite the restrictions there have been recent events of their use which have proven life threatening for instance Salisbury incident 2018. Generally the nerve gases have high volatility causing easy spread in the environment. The absorption of the harmful gases can occur via the respiratory tract, skin etc. In this paper, we propose a first principles study of the sarin nerve agent adsorbed pristine graphene nanoribbon for a vital application of nerve gas sensing. The structural, electronic and transport properties of the gas nanoribbon complexation are analysed for its viability in sarin nerve gas nanosensing application. The results obtained clearly corroborate that the pristine graphene nanoribbon can be used for sensing the presence of sarin nerve agent in the environment.
