A multi‐electrode array (MEA) biochip with excimer laser‐produced micro‐well features

Purpose – The purpose of this paper is to highlight a novel manufacturing process for a biochip with a multi‐electrode array (MEA) that is specifically designed for use in characterising cardio‐active substances and to demonstrate a novel proposed solution prototype that has been constructed to meet the needs of end‐users.Design/methodology/approach – Practical problems encountered with conventional MEA biochips are described and a novel biochip design to tackle these problems is presented. The manufacturing approach used to produce the prototypes of that design is described and depicted.Findings – The novel prototype MEA biochips were successfully manufactured using conventional electronics manufacturing approaches. Prototypes demonstrated limited successes in the early stages of testing. Further revisions of the feature geometry are required to implement an alternative MEA biochip that is suitably reliable.Research limitations/implications – Basic photolithography techniques have been used to construct ...
