Smart materials get SMARTer

Living organisms have developed sophisticated ways to maintain stability in a changing environment, withstanding fluctuations in temperature, pH, pressure, and the presence or absence of crucial molecules. The integration of similar features in artificial materials, however, has remained a challenge—until now. A Harvard (Cambridge, Mass.)-led team of engineers presented a strategy for building self-thermoregulating nanomaterials that can, in principle, be tailored to maintain a set pH, pressure, or just about any other desired parameter by meeting the environmental changes with a compensatory chemical feedback response.
