Disclosed are liquefied embolic materials capable of sol-gel phase transition in response to in vivo conditions, including temperature, ionic strength, and pH, and their uses. The liquefied embolic materials are made of copolymers based on temperature-sensitive isopropylacrylamide and ionic strength- and/or pH-sensitive monomers. In addition to finding excellent applications in the embolotherapy, the embolic materials can be used as extracellular matrixes for cell culture and for drug-delivery systems for cancer therapy.
