Introduction

Biosensing technologies have advanced significantly in recent years, enabling the detection and quantification of biomolecules with high sensitivity and specificity. Single-molecule/particle digital counting is a powerful approach that allows for ultrasensitive biosensing by detecting individual biomolecules or particles and counting them digitally. This method offers several advantages, including enhanced sensitivity, reduced background noise, and the ability to detect rare events. In this review, we discuss the principles, techniques and applications of ultrasensitive. We highlight the advancements in this field and explore its potential for various applications, including disease diagnostics, environmental monitoring and molecular biology research. Traditional biosensing methods often rely on ensemble measurements, averaging the signals from a large number of biomolecules or particles. Single-molecule/particle digital counting provides a breakthrough in biosensing by detecting and quantifying individual entities, resulting in enhanced sensitivity and detection accuracy. This review focuses on the principles and techniques underlying ultrasensitive biosensing with singlemolecule/ particle digital counting. Single-molecule/particle digital counting relies on the detection and quantification of individual biomolecules or particles, enabling the precise measurement of their concentration [1].
