Abstract :
This paper reports on a highly sensitive electrochemical based heavy metal ion sensor obtained by using recently discovered liquid metal marbles. We present the procedure to form these liquid metal marbles with controlled coating density. We also show enhanced electrochemical sensitivity of these marbles towards heavy metal ions with excellent selectivity.
