Research could lead to injectable gels that release medicines over time

The researchers dissolved polymers and nanoparticles in water, and comingled them at room temperature to solidify a Jello-like substance that - unlike its kitchen counterpart -- did not liquify at higher heat, such as in the body. The technique kept in balance two thermodynamic concepts- enthalpy, which measures energy added to or subtracted from a material, and entropy, which describes how energy changes make a material more or less orderly at the molecular level.
