Screen‐Printed Electrochemical 96‐Well Plate: a High‐Throughput Platform for Multiple Analytical Applications

Abstract

A new screen‐printed electrochemical array formed by 96 three‐electrode electrochemical cells with carbon‐based working electrodes (DRP‐96X110) was developed by DropSens. The electrochemical and electro(analytical) performance of this multiple‐analysis plate is herein presented. Different proofs of concept relying on reference benchmark redox compounds, streptavidin‐biotin high affinity interactions and magnetic‐based immunoassays were carried out. The results showed the electrochemical plate versatility and usefulness as an innovative high‐throughput transducer surface for multiple and decentralized applications.

Screen-Printed Electrodes Modified with Metal Nanoparticles for Small Molecule Sensing

“…Gold NPs were extensively used as an anchoring platform. Easy functionalization and tailor-made size, shape, and nature are advantages that offer a wide range of applications in the electrochemical sensors field [92]. A recent review deals with different approaches and novelties published until now with gold-based sensors for the detection of small molecules, DNA, and aptamers [93].…”

“…This adaptability is not confined to the materials to fabricate them (inks and substrates); it also covers their design. As said before, the most common option is printing one electrochemical cell (with three electrodes) on the substrate, but many others configurations are possible: SPEs with more than one WE sharing the same RE and CE, platforms with several complete electrochemical cells, 96-well SPE plate or even SPEs with an integrated micro-well/reactor [ 20 , 26 , 39 , 40 ] ( Figure 2 B). Thus, their high versatility together with their ease of use and portability make SPEs one of the main transducers for the development of electroanalytical devices.…”

Towards a blocking-free electrochemical immunosensing strategy for anti-transglutaminase antibodies using screen-printed electrodes

“…In addition, if screen-printed electrodes are used as the transducers, further advantages are obtained such as low cost, low reagent consumption and the ability to perform decentralized tests [6]. Moreover, novel screen-printed multichannel devices are being employed to perform multiple analysis simultaneously [7,8]. Although there has been substantial progress in the development of EBs, the way to POC diagnostic is still hard and long.…”
