Inorganic-biomolecular hybrid nanomaterials as a genetic molecular code system

A genetic code system was developed with inorganic-biomolecular hybrid nanomaterials using the base units of a DNA strand. A scanning electron microscopy (SEM) study showed that each hybrid crystal can be separated and mixed with most solution media. Superparamagnetism with excellent DNA binding capacity was combined for the development of this code system by synthesizing a polypyrrole-maghemite nanohybrid. The function of this code system extends from simple watermarks or molecular tracers to immense data storage and to the conservation of genetic information.
