Today’s scientists and engineers are nding a wide variety of ways to deliberately make materials at the nano-and microscale to take advantage of their enhanced properties such as higher strength, higher stability, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts. In the food industry, microencapsulation is more commonly used than nanoencapsulation.
