Multifunctionality is a versatile feature in nature. The human tongue is a taste sensor and also used in speech. The human nose is used for smelling and breathing. Similarly, many other organs serve multiple functions. Multifunctionality is also expected from nanosensors.

Among other functions, the human nose serves to remove particles from inhaled air. This function protects the lungs and more sensitive regions of the respiratory tract from damage due to particle deposition. The original investigation into the human nasal airway deposition was performed by Swift and Proctor (1977) with in vitro experiments on a cast reconstructed from a mold taken from a cadaver. A miniature pitot tube was used in different locations within their life-sized nasal passage replica to obtain velocity measurements. Considerable understanding of the flow field inside the human nose was gained from this study. Guilmette, Wicks, and Wolff (1989) determined, however, that this model generation method provides a less than accurate representation of the cavity of a living human as the airways are prone to collapse shortly after death.
