摘要：A system and method for creating polymer microparticles for use in drugdelivery and other applications. The components of the exemplary system include amicro-stamp having micro-contours or micro-structures, a substrate, and a sacrificial layerof material coating the slide. The method includes the steps of coating the face of stampwith a thin layer of polymer to cover the micro-structures of the stamp, contacting thecoated face of the stamp with the coated substrate to transfer polymer from the micro-structures of the stamp to the slide to create free-standing polymer microparticles, anddissolving the sacrificial layer covering the substrate to release the microparticles intosolution. The microparticles fabricated by this method typically exhibit well-definedgeometries that correspond to the micro-structures of the stamp.
