Usnea Acid‐Incorporated Ca2+/Mn2+ Ions Reservoirs for Elevated Ion‐Interference Therapy through Synergetic Biocatalysis and Osmolarity Imbalance

Ion-interference therapy (IIT) utilizes ions to disturb intracellular biological processes and has been received increasing attention in tumor treatments recently. However, the low therapeutic efficiency still hinders its further biological applications. Herein, via a simple and one-pot gas diffusion process, polyethylene glycol (PEG)-modified Mn
