Causeway Sensors are experts at manufacturing on the nanoscale – on the scale of atoms and molecules. At the nanoscale, materials and their interaction with light behave quite differently.
The company have developed a chip with a billion gold nanorods that act as interacting optical antennae. The resonant frequency of these nanostructures is highly sensitive to changes in mass at their surface, making them ideal for biological sensing applications. We have built an accompanying device that sensitively reads biological detection events at the chip surface.
