Karazin Kharkiv National University popup.description1 Contamination of surface waters with heavy metals is a global environmental concern, which has been further emphasized in the context of water pollution in Ukraine caused by Russian invasion. This project seeks to develop efficient, cost-effective optical sensors for the rapid identification of metal ions in water using carbon nanomaterials (including single-walled carbon nanotubes, derivatives of graphene oxide and fullerenes) and nanofibrils derived from proteins extracted from organic waste. In particular, the project includes the valorization of food and industrial waste for the development of effective highly-adsorptive biosensors and water purification systems. Optical sensor systems for identifying metal ions in water will be created through the functionalization and optimization of carbon nanomaterials and nanofibrils with the fluorophores and/or proteins. popup.description2 This project is focused on the development of efficient, cost-effective nanosystems for rapid identification of metal ions in water, based on nanomaterials functionalized with fluorescent probes, in particular protein nanofibrils. A spectroscopic analysis of dyes from various classes was performed to evaluate their sensitivity to heavy metal ions in aqueous solutions. The study identified the promising potential of squaraine and benzanthrone dyes in combination with β-lactoglobulin fibrils for the development of metal-specific sensing systems. A comprehensive investigation of the binding of heavy metals Cd²⁺ and Co³⁺ to soybean 7S globulin was conducted to assess the influence of protein structure on metal-binding capacity and selectivity. It was demonstrated that Cd²⁺ and Co³⁺ can destabilize β-chain protein structures and alter its conformation, while low metal concentrations do not disrupt structural stability. The properties of micelles of 3-(dimethyldodecylammonio)-propanesulfonate and CTAB, oligomeric silsesquioxanes functionalized with surfactants, proteins and amyloid fibrils, nanogels, and lipid vesicles were also investigated for the potential creation of sensor platforms based on these systems. In particular, important insights were obtained regarding the design of surfaces functionalized with surfactants, including nanotubes coated with surfactant bilayers and other related nanostructures.
