ASG Biosensor

  ASG first applied its technology to solar photovoltaics and it is playing an important role in that industry bringing down costs and improving the efficiency of solar cells, but ASG’s technology has many applications. A few years ago, ASG began working on a novel concept: using its silicon nanowire and semiconductor know-how to create a unique planar silicon biosensor.

ASG’s patented biosensor works by combining known approaches to sensitizing silicon to organic biological molecules with photoelectric principles to create a highly sensitive quantitative measurement technique for specific analytes in solution. The device design allows for detection of multiple analytes in the same test: proteins, nucleic acids, and more. 

Nanowires have a high surface area to volume ratio making them sensitive to their environment. This allows the measurement of dilute concentrations - pico-gram/ml detection is possible. 

ASG’s design allows for low cost processing with the potential to reduce the cost of testing for proteins and other biological molecules in solution in many areas of medicine and the life 

sciences.
