Abstract
Provided herein are photodynamic compositions that can contain a natural polymer scaffold and a photosensitizer, where the photosensitizer can be covalently or non-covalently attached to the natural polymer scaffold. Also provided herein are structures and objects that can contain the photodynamic compositions. Further provided herein are methods of making and using the photodynamic compositions. Finally provided herein are printing ink formulations.
Claims26
A composition comprising:
- a natural polymer scaffold, wherein the natural polymer scaffold is selected from the group consisting of:
- nanocrystalline cellulose, cellulose fibers, lignin, chitin, chitosan, nanofibrillated chitosan, poly-glucosamine, wool, silk, cotton, and any permissible combinations thereof;
- and
- a photosensitizer, wherein the photosensitizer is attached to the natural polymer scaffold by a non-covalent bond, wherein the non-covalent bond is an electrostatic interaction, hydrogen-bonding interaction, or a hydrophobic interaction, and wherein the photosensitizer is a positively charged photosensitizer.
