abstract = {In this paper, surface renewable carbon microelectrode
arrays (MEAs) were developed using microfabrication
technology and were successfully applied in heavy metal ion
sensing. The as-prepared carbon microelectrode was
fabricated with a cylindrical shape 50 μm in diameter and
300 μm in height. Cyclic voltammetry (CV) analysis with
scan rates ranging from 10 mV s−1 to 100 mV s−1 was
utilized to characterize the MEAs, and it was found that the
typical properties (flat redox peaks) of MEAs appeared at
lower scan rates (<30 mV s−1). Heavy metal ions, including
Cd2+, Pb2+ and Cu2+ were chosen to demonstrate the
performance of the developed MEAs for electrochemical sensor
applications, with the detection limit calculated to be 1
μg L−1. Renewability and repeatability experiments were
also carried out to demonstrate the good characteristics of
the MEAs. This work developed a novel microfabrication
technique for low cost surface renewable MEAs that can be
used as an electrochemical platform for a wide range of
sensor applications.},
