ABSTRACT
Embossing or embedding of nanoparticles into a polymeric film is realized by an electromagnetic field. Upon laser light illumination nanoparticles absorb energy, convert it to heat, and sink into a locally softened polymer film as probed by atomic force microscope. The polymeric matrix forms a characteristic rim and surrounds the lower part of the nanoparticles; the upper part of the nanoparticles is left unexposed to the ambient phase. This imprinting method is thought to have an impact on ultrahigh-density data storage, measurements of fundamental thermal parameters of materials, and fabrication of asymmetrical, Janus-type nanoparticles.
