The NanoArrayer bench-top ultramicro- and nanoscale fluid delivery system is a multifaceted platform capable of delivering femtoliter to attoliter volumes of solutions containing biomolecules and other materials to defined locations on surfaces with ultramicro (1-20 μm) feature sizes and nanometer spatial resolution. The ultraminiaturized nature of the technology reduces sample requirements to a bare minimum. For example, the unit can create a diagnostic biochip that uses just a few cells, or less than one drop of blood, for biomedical analysis. The NanoArrayer works with a wide range of compatible materials and has broad applicability in the life sciences, including fields such as cancer and disease diagnostics and cellular research.
