Immunoassay biosensors make identifying animal proteins from egg or glue in cultural heritage objects an simple task. This effort to miniaturize and simplify analysis could bring material characterization to any conservation studio. Continue reading Protein analysis in heritage materials: from medical to conservation diagnosis with mini-biosensors
X-rays help researchers understand the elemental profile of an artwork. A new X-ray fluorescence imaging system, inspired by a similar system being developed for planetary exploration missions, brings high-resolution elemental mapping directly into the galleries in an accessible way. Continue reading From Mars to the museum: The application of full-field X-ray fluorescence (XRF) to the study of a Caillebotte painting
Mølen, the Norwegian site of hundreds of ancient grave cairns, is constantly at risk, largely due to the influence of visitors to the site. Sites such as these must be monitored to see if changes have occurred, but since data from modern technologies do not date back very far, it is often necessary to use other types of archival data to fill in the gaps. Continue reading Stop moving the rocks around: Monitoring of Mølen using digital elevation models
On the surface of every folio of every manuscript lies a hidden library of genomic information to be sequenced, translated, and interpreted. Eraser shavings collected during the dry cleaning of these valuable documents can be used to access this metalibrary without destructive sampling.

A gaseous degradation product of some museum materials is acetic acid, which in turn can catalyze their own further degradation. To combat this cyclical phenomenon, molecular organic frameworks have been harnessed to preferentially capture acetic acid from the museum environment. Continue reading The MOF—a metal organic ultraporous ‘sponge’ for gaseous vinegar
