Non enzymatic electrochemical sensors employing precious metals like platinum gold

Non-enzymatic electrochemical sensors employing precious metals like platinum, gold and their alloys [12] and [13] are reported to show excellent performance but sometimes their cost is prohibitive, unaffordable by many. Further platinum and platinum based alloys are prone to get poisoned by some of the products in the analytes and also interference from other biomolecules like ascorbic acid, dopamine etc. has been observed [14]. Common and cheaper metals like copper, cobalt and nickel and their oxides are shown to possess good electrocatalytic activity towards the Sorafenib Tosylate of glucose, in alkaline medium [15], [16], [17] and [18].
