How to develop digital biosensors with higher sensitivity and faster reactions

Digital biosensors are redefining how we detect and quantify biomolecules, offering single-molecule sensitivity and near-instant results outside the lab. By converting biochemical interactions into clear, digital signals, they enable rapid and precise diagnostics at the point of need. This guide examines the key performance metrics of each material, including sensitivity, cost, scalability and biocompatibility.

This guide outlines the key strategies for developing digital biosensors that deliver reliable performance, explores the material hurdles that hold many designs back and introduces how new carbon nano-materials can unlock the next generation of ultra-sensitive, rapid-response digital diagnostics.
