Researchers Create Ultra-Sensitive Robotic Nose Using Frog Eggs As An Olfactory Sensor
Detecting Molecules with Frog Eggs
From Popular Science:
Researchers at the University of Tokyo are using frog eggs to enhance what might seem like an unlikely element of robotics: olfactory sensing. By injecting the eggs with the DNA from various insects known for expressing keen senses of smell, the team was able to create a robotic nose that can detect molecules at levels as low as a few parts per billion.
