Nanobiochips.

The actual progress towards biological chip devices consisting of nanostructured functional entities is summarized. The practical aspects of molecular nanobiochips are discussed, including the main surface chemistry platforms, as well as conventional and unconventional fabrication tools. Several successful biological demonstrations of the first generation of nanobiochip devices (mainly, different nanoarrays) are highlighted with the aim of revealing the potential of this technology in life sciences, medicine, and related areas.
