The present disclosure provides photo-polymerizable monomers, photo-curable resins comprising one or more of such monomers, as well as polymeric materials formed from the photo-curable resins. Further provided herein are methods of producing the compositions and using the same for the fabrication of medical devices, such as orthodontic appliances.

Methods of detecting and, optionally, determining a level of incorporation of monolignol ester conjugates into lignin. The methods include derivatizing lignin to acylate at least a portion of free phenolic and aliphatic hydroxyls and to halogenate at least a portion of benzylic alcohols present in the lignin to yield derivatized lignin, treating the derivatized lignin with a reducing agent to cleave at least a portion of the derivatized lignin to yield lignin cleavage products, acetylating at least a portion of free hydroxyl groups in the lignin cleavage products with a labeled acetylation agent to yield labeled lignin fragments, and detecting the labeled lignin fragments.
