change the components of the system. Appropriate combination of logic gates leads to some kinds

12.5 FUTURE PERSPECTIVES
The accumulation of higher order functions into nanosized space leads to an incredibly low-energy
process, which can save limited amounts of energy sources and can suppress environmental pollu-
tion. The construction of the nanosized functional system with only artifi cial materials is surely dif-
fi cult. In contrast, nature has already overcome this problem long time ago, that is, living creatures
have many reactors and information converters in their body. Therefore, preparation of biohybrid
nanomaterials would provide realistic solution for the development of human-made devices.
As conceptually illustrated in Figure 12.25, organizing processes (assembly, hybridization, and
hierarchic structuring) of functional elements are indispensable for the preparation of functional
