Modular DNA nanosensors enable state-aware multiplexed single-molecule mass photometry in complex media

Seham Helmi, Roi Asor, Maya Miller…·Philipp Kukura

This paper introduces modular DNA nanosensors that enable label-free, multiplexed single-molecule mass photometry to resolve protein biochemical states in complex media without washing or immobilisation.
