INPATT (Inorganic Photochemical pATTerning): Precipitation of calcium carbonate induced by light in a perspective of micropatterning application

INPATT is a Proof of Concept ERC (Horizon Europe) project aimed at developing the photo-induced precipitation of calcium minerals. The main idea behind the project is that light-controlled precipitation can be achieved using molecules that release functional moieties (as carbonate or phosphate groups), which subsequently precipitate in the presence of calcium ions. The absorbance of these cleavable molecules can be tuned to the preferred wavelength and therefore, these processes can be adapted to non-invasive conditions, using aqueous solutions, bio-compatible matrices, and a non-harmful irradiation wavelength. This dataset contains characterization analysis of light induced calcium carbonate precipitates, obtained by two main techniques. The first approach, based on a previous publication (Menichetti et al, 2021, DOI:10.1002/chem.202102321), aimed to the photo-precipitation of calcium carbonate by means of Ketoprofen as photoactive molecule which was optimized to obtain a fluid paste. Secondly, calcium carbonate photo-precipitation was investigated in presence of a photocurable polymeric resin.
