Integration of Biotechnology
and Nanotechnology

We have five senses: vision, hearing, touch, smell, and taste. Although some other senses including balance, pain, itch, and temperature senses have been reported, the five senses remain major classical senses. Among these five senses, three of them: vision, hearing, and touch, recognize physical stimuli, and the other two senses recognize chemical stimuli. The science and technology concerned with vision and hearing have been advanced enormously, while the understanding of the chemical senses, especially the sense of smell, has been very limited.
