Virus lasers for biological detection. [PDF]
Nat Commun, 2019 AbstractThe selective amplification of DNA in the polymerase chain reaction is used to exponentially increase the signal in molecular diagnostics for nucleic acids, but there are no analogous techniques for signal enhancement in clinical tests for proteins or cells.

Biologically inspired edge detection [PDF]
2011 11th International Conference on Intelligent Systems Design and Applications, 2011 Inspired by the structure and behaviour of the human visual system, we present an approach to edge detection using spiking neural networks and a biologically plausible hexagonal pixel arrangement. Standard digital images are converted into a hexagonal pixel representation and then processed using a spiking neural network with hexagonal shaped receptive

Detecting Biological Warfare Agents [PDF]
Emerging Infectious Diseases, 2005 We developed a fiber-optic, microsphere-based, high-density array composed of 18 species-specific probe microsensors to identify biological warfare agents. We simultaneously identified multiple biological warfare agents in environmental samples by looking at specific probe responses after hybridization and response patterns of the multiplexed array.
