http://www.freepatentsonline.com/7736893.html

This patent from SII Nanotechnology teaches an interesting method to culture artificial internal organs using optical trapping to manipulate individual cells. Claim 1 reads:

1. A method of producing a nanobio device of imitative anatomy structure, comprising the steps of:

manufacturing a substrate for a nanobio device by focused ion beam processing, the substrate having an array of chambers with walls formed as partitions that separate the chambers; and
arranging individual cells, from among a plurality of types of cultured cells, in individual chambers using optical tweezers to permit interaction among the cells to produce a nanobio device of imitative anatomy structure.
