Anti‐Icing Organogel Enables Quasi‐Homogeneous Supercooling Preservation of Mouse Hearts
Advanced Science, EarlyView.An organogel interface with a large energy barrier for ice nucleation is proposed to enable a quasi‐homogeneous supercooling preservation for organs. This method does not rely on cryoprotectant agents or machine perfusion and can double the ex vivo storage time of mouse hearts.
