1.16 Some Examples of Nanosensors
1.16.1 Common Nanosensors
At present, the most commonly observed nanosensors exist in nature in
the biological world as natural receptors of outside stimulation. Animals
like dogs have a strong sense of smell that functions using receptors that
feel nanosized molecules. Various shes use nanosensors to perceive
minuscule vibrations in the surrounding water; several insects detect sex
pheromones using nanosensors. Similar to
