The photozymes (P) are amphiphilic water-soluble copolymers consisting of hydrophobic chromophoric and hydrophilic monomer units forming nanosized pseudo-micelles which hydrophobic core allows to transfer the solar energy into chemical energy due to the antenna effect (AE) with single oxygen production (SOP) and the tailored photochemical transformation of the solubilized in the hydrophobic pocket molecules. The co-existence of these two distinctive for the photosynthesis effects in P opens wide range of possible technological innovation developments.
The goal of PhotoNanoTech (PNT) is to develop new nano-based processes with long-term applications in the wastewater decontamination (WD), textile processing, biomedical coating and materials development, as w ell as for bone regeneration. New P will be synthesized to this goal, using zwitterionic (ZI) monomers providing them specific antipolyelectrolyte properties, salt-philicity as well as a unique self-organization ability (SOA), similar to that of phospholipids (PL).
AE-induced chemical reactions of the solubilized hydrophobic compounds are the fundament of P applications for the photocatalytic WD. pH-independent photocatalytic WD from dissolved hydrophobic compounds and damaging inorganic salts are the ad vantages of the suggested ZIP. The combination of AE and SOP could find a new and promising application for making self-cleaning textiles. PL vesicles are the place for the calcium phosphate nuclei formation and grow. PNT will exploit SOA of ZI P for their participation in the biomineralization (BZ) process. Photosensitizing characteristics of ZI P included in such vesicles opens the opportunity for light-controllable BZ, called photodynamic BZ. A valuable property of ZI-based materials is their bio-compatibility. PNT includes the production of such materials (by photo-induced graft-co-polymerisation) with suppressed inflammatory response, enhanced bio-lubrication characteristics and haemocompatibility.
