Ultrahigh Transparent and Toughness Copolymer Eutectogels via Phase Separation for Fast Tissue Clearing and 2D/3D Imaging

). The strong mechanical strength of the eutectogel improves tissue strength by more than 120-fold, facilitating the procurement of high-resolution two-dimensional images of cells and subcellular structures. It also offers a wide range of dynamic tunability, thereby providing a universal platform for diverse applications spanning biomedicine to tissue engineering.
