Porous Silicon Sensors

Caption: This image illustrates the enormous increase in surface area possessed by porous silicon sensors. If we assume a traditional sensor can capture molecules on an area equivalent to that of a golf ball, then a similarly sized porous silicon sensor has enough surface area to capture molecules on an area equivalent to that of a football field. The ability to capture more molecules increases the probability and sensitivity of detecting small molecules such as DNA or toxins.
