Abstract
- Efficient and reliable methods for the generation of bioactive papers are of growing interest in relation to point‐of‐care testing devices that do not require extensive analytical equipment. Herein, we report the immobilization of functional proteins on paper fibers using a modular chemoenzymatic approach. The synthetic strategy relies on a combination of highly efficient spatially controllable photo‐triggered cycloaddition followed by site‐specific sortase A‐catalyzed transamidation. This site‐directed and regiospecific method has allowed unidirectional and covalent immobilization of several proteins displaying different functional properties, with ramifications for application in paper‐based diagnostics. Protein‐functionalized paper: A modular approach to covalent protein immobilization on paper fibers is reported, which relies on a set of highly efficient pericyclic reactions in combination with site‐specific enzymatic coupling. Following initial derivatization of a cellulosic surface (see figure), light‐triggered covalent anchoring of an enzyme recognition site ensures enzyme‐promoted ligation of desired proteins with preservation of their function.
