Akubio was formed in August 2001 to exploit highly sensitive acoustic detection technology discovered by scientists at the University of Cambridge, UK. The technology enables rapid, label-free determination of molecular interactions. Receptor–ligand interactions can be probed either in buffered solutions or in complex biological fluids, as the detection process is not adversely affected by non-specific binding of sample contaminants. Applications are being developed for the diagnosis of clinical infections, the screening of libraries for receptor binding, and the determination of molecular interaction affinities in general.
