Since phototrophs rely on light as an energy source through photosynthesis, the artificial extension of the natural photoperiod can impact microalgae and cyanobacteria dwelling on stone surfaces. These organisms form subaerial biofilms (SABs), which lead to biofouling of building materials and pose challenges for heritage conservation. For the first time, the present study looked in depth at what happens at the SAB-substrate interface when biofilm formation occurs under daylight followed by ornamental lighting. Granite (the main material in historical buildings and structures in NW Spain and many other regions of the world) and cement (the most widely used material for construction, especially in modern and contemporary architecture) have been used as test substrates, inhabited by algal biofilms mainly composed by the green algae &lt;em&gt;Bracteacoccus minor&lt;/em&gt; and &lt;em&gt;Stichococcus bacillaris&lt;/em&gt;. Tests were conducted after a 3-month exposure to different ornamental LED light conditions. The tested conditions comprised a photoperiod of 13 h of daylight, followed by 6 h of exposure to different ornamental LED illumination, and 5 h of darkness (imitating the photoperiod of ornamentally illuminated monuments). The ornamental LED lighting conditions tested were an innovative amber+green light (at 3000 K, with biostatic effect and under trial), two lights suitable for illuminating the urban fabric: warm white light (at 2580 K, with a yellower hue) and cool white light (at 4600 K, with bluer hue), and a reference scenario without ornamental lighting (i.e., darkness). Blank specimens without colonization were also included. Surface roughness and hardness, VIS-light spectrophotometry, static contact angle and water absorption, as well as petrographic and 3D microscopy, were used to evaluate the lighting impact on the SABs interactions with the building material substrates. The presence of SAB increased the surface hardness, water absorption time and static contact angle while reducing the surface hardness of both the granite and mortar specimens. The SAB-substrate interface exposed to amber+green light behaved similarly to the biofouled specimens without ornamental illumination, minimizing its effects in comparison to both white lights tested, which further affected those parameters. The color differences of the surface, changed by the ornamental lighting conditions, were also minimized under the amber+green light. The results suggest a lower level of SAB development under the innovative amber+green light. Petrographic microscopy of thin sections reveals differential SAB coverage across the granite surface, depending on local mineralogical differences, with biotite appearing uncolonized. In the mortar specimens, the SAB was thinner and appeared to fill the macropores. The results can inform the design of more effective ornamental lighting strategies in cities,","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"78 ","pages":"Pages 7-20"},"PeriodicalIF":3.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146036976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spiral-grooved notches suggest a unique Hongshan cutting technique involving hole-drilling and the use of a sand-coated rope to split the jade.

Spectral analysis confirmed that the beads are made of tremolite, showing minimal weathering and excellent preservation. Elemental profiling highlighted consistent Ca/Ba ratios, while distinct Mn/Fe and Ni patterns suggest the potential for distinguishing nephrite sources. This analysis indicates that the jade beads may originate from Xiuyan nephrite. Additionally, multispectral imaging further supports this provenance conclusion.

To overcome these limitations, we applied indirect ELISA assays using both polyclonal antibodies and synthetic aptamers to detect specific proteins and a cereal polysaccharide in ceramic sherds from two hilltop sites in north-eastern Slovenia: an early medieval settlement beneath Ptuj Castle (7th-9th centuries CE) and a Late Roman–early medieval fortified site at Ančnikovo Gradišče (4–5th, 7–10th centuries CE). Sherds bearing charred cooking residues were powder-extracted and assayed on MaxiSorp microtiter plates for six protein targets (ovalbumin, lysozyme, gluten, casein, collagen, and myosin) and for (1→3)-β-<span>d</span>-glucan target using matching primary antibodies and biotinylated DNA aptamers, with detection achieved by adding alkaline phosphatase–conjugated secondary antibodies to label primary antibody binding or alkaline phosphatase–conjugated streptavidin to label aptamer binding. At Ptuj, both formats identified egg proteins, bone collagen, myosin and gluten on individual sherds, with aptamers consistently yielding larger ΔOD margins than antibodies. At Ančnikovo Gradišče, meat residues dominated: myosin and collagen were detected on most Late Roman sherds, while sherd 402 (early medieval) uniquely registered cereal markers—gliadin and β-<span>d</span>-glucan—alongside meat and egg proteins. Casein appeared in only one Late Roman vessel. Co-occurrence of animal and plant residues implies composite dishes such as stews or porridges. Our findings demonstrate that aptamer‐based ELISAs offer enhanced sensitivity for archaeological proteins, and that protein and polysaccharide residue analysis can reconstruct nuanced dietary patterns. This approach holds promise for broad application in contexts lacking textual records.

Thus, it provides valuable insights into structural stability, invisible overlapping of detachments and cracks, hidden structured layers, and through defect propagation to trace the future deterioration risks.
