There are several summaries at the left panel:

Every panel is expandable and shows the types of elements found for the particular query

Expand the Projects panel and click on GRACIOUS. This will filter the results and only data generated by GRACIOUS project will be shown.


The filters can be combined.

Expand the Nanomaterial type panel and select quantum dot. These are ontology terms assigned to each material , e.g. NPO_589


The panels show the types and counts of elements found for the particular query

i.e, the GRACIOUS project and quantum dot materials in this case.

The Methods panel shown indicate there is GRACIOUS data for quantum dot measured by these methods. The Method annotation panel contains the ontology terms denoting the same methods.

Data entry

While the eNanoMapper database supports structured formats for data import (e.g. IUCLID5/6 files, W3C RDF), JSON, the data originating from NanoSafety Cluster during the last decade is predominantly provided in the form of custom spreadsheet (MS Excel) templates.

To steer the spreadsheet layout design towards harmonization, while retaining the user friendliness and the features deemed important by the labs, we provide a
Template Wizard


Template Wizard

The files will be taken from the agreed results location, assigned a NMDataParser configuration and imported into project-specific eNanoMapper database instance, using the eNanoMapper FAIRification workflow
