Error reduction in biosensors using secondary labeling

TL;DR

This paper derives the detection limit for a two-step biosensor process and demonstrates that error rates can be minimized similarly to non-equilibrium methods like kinetic proofreading.

Contribution

It provides a theoretical framework for error reduction in biosensors using equilibrium recognition processes, linking to non-equilibrium strategies.

Findings

Derived the limit of detection for two-step recognition

Showed error rates can be minimized as in kinetic proofreading

Established a theoretical basis for biosensor accuracy improvement

Abstract

In this article, we derive the limit of detection for a two-step molecular recognition process and show that in-spite of all the recognition reactions being in equilibrium the overall error rates can be reduced exactly as much as possible in non-equilibrium methods such as kinetic proofreading.
