Challenges › Solutions

When powerful technology becomes accessible,
scientific progress accelerates

Traditional Approach

Limited access to dynamic molecular insight

Structural and bulk methods primarily report static or averaged states, obscuring heterogeneity and transient behaviour
Single-molecule experiments typically require large, specialised, or custom-built infrastructure, inaccessible to the broader community
Experimental possibilities are constrained by available infrastructure rather than scientific questions
Complex workflows to set up, maintain and use instruments prevent adoption by non-technical scientists
Data analysis is based on custom, specialised data analysis workflows that depend on individual coding skills and legacy analysis scripts

EI-FLEX

Routine access to single-molecule dynamics and interactions, directly in solution

Direct observation of molecular dynamics and conformational heterogeneity under physiologically relevant conditions
Benchtop platform enabling single-molecule measurements directly in solution
Guided alignment, data acquisition, and integrated analysis lower the barrier to high-quality experiments
Multiple single-molecule methods accessible within a single, unified experimental framework
Reproducible, reliable single-molecule data across projects, users, and laboratories

Our mission

Across research and drug discovery, critical decisions are often made with incomplete insight – rare states are averaged out, transient behaviours are missed, and uncertainty slows progress.

Our mission is to change that. We exist to offer true single-molecule sensitivity – the ultimate resolution, at the moment it matters, so teams can quickly move from assumptions to understanding, and from risk to confidence.

By removing the barriers that once limited access to high-resolution dynamic insight, we enable researchers – in academia and industry alike – to ask better questions, resolve complexity earlier, and accelerate the journey from discovery to real-world impact.
