Physicochemical Features and Applicability of Newly Fabricated Phytopharmaceutical-Loaded Hydrogel Alginate Microcarriers with Viscoelastic Polyelectrolyte Coatings.

The design of novel polymeric carrier systems with functional coatings is of great interest for delivering various bioactive molecules. Microcapsules coated with polyelectrolyte (PE) films provide additional functionality and fine-tuning advantages essential for controlled drug release. We developed hydrogel microcarriers coated with functional PE films with encapsulated substances of natural origin, resveratrol (RES), curcumin (CUR), and epigallocatechin gallate (EGCG), which have cytotoxic and chemopreventive properties.

Wettability of Graffiti Coatings by Green Nanostructured Fluids.

Green nanostructured fluids (GNFs), specifically water-in-oil nanoemulsions (w/o NEs), were investigated as professional "brush on, wipe off" nanodetergents for the effective removal of various challenging graffiti coatings. The efficacy of the advanced nanodetergents in eradicating resilient graffiti coatings was evaluated using various methods to assess the surface properties of forming graffiti coatings. The surface properties of these coatings were examined by assessing their wettability by water, surface free energy, and topography to obtain information on the intermolecular interactions with the nanodetergent during the wetting and graffiti removal process.
