| abstract |
The invention provides a device comprising a substrate having a surface capable of attaching a plurality of moieties, or a surface having a plurality of moieties attached thereto. The substrate also contains machine-readable information realting to themoieties. The information may be contained in a discrete regions of the substrate that is non-coplanar with respect to the substrate surface having the plurality of moieties attached thereto. The information may, for example, relate to the identity of the attached moieties or to instructions for attaching the moieties. Also provided are methods and machines for forming and using the devices. |
