Green Synthesis of Silver Nanoparticles from Plant Extracts for the Removal of Moss from Stone Heritage Buildings

1. Moss chlorophyll data
This dataset contains measurements of chlorophyll a concentration in moss samples collected from stone surfaces at Yunfeng Tunpu, treated with varying concentrations of silver nanoparticles (AgNPs) and benzalkonium chloride (BC). Measurements were taken on days 1, 15, and 30 using spectrophotometry at wavelengths of 665 nm and 649 nm, with concentrations calculated according to the standard formula. The data were used to evaluate the inhibitory effect of the antimicrobial agents on the photosynthetic capacity of the moss.

2. Moss Treatment Micrograph
This dataset comprises micrographs of moss samples after treatment with antimicrobial agents. The images illustrate changes in moss cell morphology and pigmentation (chlorophyll) before and after treatment, providing visual evidence of the damaging effects of the agents (e.g., silver nanoparticles) on the moss. These images serve as crucial visual documentation for assessing moss removal efficacy.

3.Scanning Electron Microscope (SEM) images

This dataset contains scanning electron microscope (SEM) images of silver nanoparticles (AgNPs) green-synthesized using aqueous and ethanolic extracts of four plants (cinnamon, clove, thyme, Agastache rugosa). The images reveal the morphology (predominantly spherical) and size distribution of the synthesized AgNPs. These data are a key component of the physical characterization of the nanoparticles.

4. Soluble protein data
This dataset records the soluble protein content in moss samples treated with different agents (AgNPs, BC). The protein content was measured using the Bradford method (Coomassie Brilliant Blue G-250) at a wavelength of 595 nm and is expressed as micrograms per gram of moss fresh weight (μg/g). This data was used to analyze the impact of antimicrobial agents on the metabolic activity of moss cells.

5.Species identification data
This dataset contains information and results related to the species identification of moss samples collected from stone heritage surfaces at Yunfeng Tunpu. It primarily includes morphological characteristics descriptions and photomicrographs obtained using stereomicroscopy and light microscopy, along with the final list of identified species (e.g., Brachythecium procumbens, Erythrodontium julaceum). Identification was performed with reference to "Flora Bryophytorum Sinicorum" and "Moss Flora of Guizhou".
