The multiple technologies needed to make a successful biochip -- from sensing chemistry, to microarraying, to signal processing -- require a true multidisciplinary approach, making the barrier to entry steep.
Due to the use of 8 separate microarrays per biochip, seven replicate intensity readings are made available and the median value is generally applied to the graphical results.
The biochip can test the interaction of the drug, light, and oxygen simultaneously, generating results in a fraction of the time of current testing practices.
The difference from conventional immunoassays is that the capture ligands are covalently attached to the surface of the biochip in an ordered array rather than in solution.
