"tissue-level moduli as soft as 81 kPa, 150% strain stretchability,  up to 1.4 cm2 V-1 s-1 charge-carrier mobility... soft mechanical properties/ large degree of hydration... hydrogel very porous allowing efficient diffusion transport... solvent exchange, dissolving semiconductors in organic solvent, then immersed into water dissolving out organic solvent/ letting water in... semiconducting properties/ hydrogel... reduces immune response/ inflammation... elevated biosensing response, stronger photo-modulation effects:"
