The traditional three-electrode electrochemical system used in the development of biosensors for detecting various biomarkers of interest necessitates the use of bulk electrodes, which precludes the deployment of handheld electrochemical devices in clinical applications. Affordable screen-printed carbon electrodes (SPCEs) modified with functional interfaces are being developed to enhance the sensitivity of a compact sensing system as a whole. In this work, SPCEs were fabricated on an overhead projection (OHP) sheet in three different active areas of 2 × 2, 3 × 3, and 4 × 4 mm using a screen printing technique, and then ∼2 nm sized graphene quantum dots (GQDs) were electrodeposited over the SPCE surface to add functionality for the detection of ultralow levels of one of the cardiac biomarkers, C-reactive protein (CRP).

Article Synopsis
  • SARS-CoV-2 has caused the ongoing COVID-19 pandemic, highlighting the need for systematic testing to control its spread through isolation and contact tracing.
  • A major challenge in testing is the limited availability of diagnostic resources; pooled testing could help by combining samples to reduce costs and resource use.
  • This article reviews current pooled testing models and suggests practical guidelines for large-scale implementation to improve testing efficiency and help flatten the infection curve.
