摘要：

Melting away: Phase-change materials (PCMs) are used to encapsulate colloidal particles with FITC-dextran to demonstrate a new temperature-sensitive drug release system. As the temperature is increased to the melting point of the PCM, the particles leach out, followed by release of FITC-dextran. The initiation and rate of release can be manipulated by using different combinations of materials for the PCM and colloidal particles. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
