The capability to fabricate nanoscale structures is a fundamental step toward realizing the promise and potential of nanotechnology. We report on precise manipulation and thermal processing using 100-nm polystyrene latex nanoparticies. This approach is illustrated by fabricating a three-dimensional nanostructure by using an AFM tip to position nanoparttcles and then thermally processing to "sinter" the particles to form a contiguous, stable structure. We suggest that this Is a general approach, but the use of polystyrene latex particles offers an advantage of low-temperature processing. Use of polystyrene latex also extends the range of materials for which we have demonstrated manipulation and suggests applications including fluorescent doping and electrically conducting polymers.
