Release Notes
This release introduces a new conformational change analysis and focuses on clearer chip status feedback, more efficient bulk operations, streamlined assay workflow creation, and cleaner device management.
New Conformational Change Analysis
heliOS 2026.2 introduces a newly developed conformational change analysis utilizing DNA origami nanolevers.
In contrast to the previously used Dynamic Lag model, the new analysis is centered around directly quantifying differences in molecular friction by measuring differential oscillation velocities of proteins and other biomolecules across distinct conformational states.
Subtle changes in three-dimensional molecular geometry can thus be detected upon analyte binding, manifested as significant differences in velocities.
Quantifying conformational change this way offers the advantage of a direct proportional relationship to variations in hydrodynamic radius, improving physical interpretability of results while retaining a clear and intuitive analytical framework.

Expired Chips
To ensure data quality and experimental integrity, heliOS now provides clear indications when expired chips are used or detected on the device.
Warning in Experiments View
If an experiment was performed using one or more expired chips, heliOS will now display a warning.
A new Chip tab, marked with an exclamation icon, is added to the experiment view. This tab lists the IDs of all expired chips involved in the measurement, helping you quickly identify potential impacts on your results.

Highlighting on Device
Expired chips are now also highlighted directly in the device’s Chip tray view.
If a chip is detected as expired, its position is marked with an orange warning indicator. Hovering over the expired chip provides a tooltip warning: “Expired chip: functionality may be compromised.”

Enable Bulk Actions for Documents
Managing documents is now more efficient. In previous releases, Methods, Assay Workflows, and Experiments could only be selected one at a time for deletion or export.
With this release, you can now select multiple documents and export or delete them in one action.
Selecting Multiple Documents
Document lists now support standard multi-selection behavior:
- Hold Ctrl and click individual documents to add or remove them from the selection.
- Click the first document, then hold Shift and click another document to select the full range between them.

Deleting Multiple Documents
You can now select multiple documents and delete them in one action.

Exporting and Importing Multiple Documents
Multiple selected documents can now be exported together into a single heliOS export file. This makes it easier to transfer related Methods, Assay Workflows, and Experiments between heliOS installations.
heliOS export files now use the dedicated .hos file extension instead of the generic .zip extension.
This clearly distinguishes heliOS exports from regular zip archives and helps prevent import issues caused by selecting files that were not created by heliOS.
Multiple heliOS documents can now be imported from one .hos file.
Previous .zip files can still be imported by selecting the “Legacy heliOS export” format during importing.

Dedicated heliOS Export File Icon
Files with the .hos extension now use a dedicated heliOS export icon. This icon is different from the heliOS application icon, making exported document packages easier to recognize in the file system.

Downloading Multiple Experiments at Once
Previously, downloading multiple experiments was cumbersome, as only one experiment could be downloaded at a time.
With this release, you can now download multiple experiments simultaneously, significantly speeding up the process.

Deleting Experiments From a Device
In previous releases, it was not possible to delete experiments from a device, which could lead to devices becoming cluttered with experiments that were no longer needed.
With this release, you can now remove experiments from a device, making it easier to keep devices clean and organized.

Simplified Assay Workflow Creation
This release introduces several improvements to make creating and managing assay workflows faster and more intuitive.
Add Assays with a Single Click
Assays can now be added to a workflow with a single click, reducing the number of required steps.
Newly added assays are placed at the end of the existing workflow.

Add Multiple Assays at Once
Multiple assays can now be added to a workflow in a single step, reducing repetitive actions.
They are appended to the end of the current workflow.

Drag and Drop Multiple Assays into a Specific Position Within an Assay Workflow
To add multiple assays at a specific position within a workflow, you can now use drag and drop to position them directly at the desired location.

Duplicate Multiple Assays Within a Workflow
You can now duplicate multiple assays within a workflow. The duplicated assays are inserted directly after the last of the selected assays.
This makes it easier to reuse and replicate existing configurations.
Overall, these enhancements significantly simplify and accelerate the process of building assay workflows.
Deprecation of Predefined Assays
Predefined assays were previously used to quickly create assay workflows.
In recent years, we have moved to a more flexible process based on verified methods, which are delivered independently of heliOS.
Verified methods provide a unified way to create assay workflows and help ensure that your assays are always up to date and compatible with your devices.
As a result, we have decided to deprecate predefined assays in favor of verified methods.
From this release onward, adding predefined assays to a workflow is no longer supported.
Assay workflows that contain predefined assays can still be run, but support for them will be removed in future releases.
Please upgrade your assay workflows to use verified methods so they benefit from the latest and most accurate assay configurations.
