This work is being reported and communicated with the Proceedings of the National Academy of Sciences. In contrast to inkjet printed electronics or some kind of previous self-assembly techniques, it could be helpful in allowing the large scale assembly of high-quality electronic components on the materials, which are of the same type. The assembling of devices has been so far done through the so-called sedimentation, which has been considered as the efforts, which can exploit the effect of gravity.

The precisely shaped components are being etched with depressions, so that they can be matched with the etched black devices. The person, who has been leading this research work, Heiko Jacobs of the University of Minnesota, has said that he and his team members have been working for at least two years and have not been successful in assembling the components with high yield, as the gravity has not been working at all.
