The adsorption of biomolecules on surfaces is dependent on biomolecule molecular descriptors, surface descriptors and environment descriptors. Of these descriptors, the biomolecular-related are the most complex and arguably the most important, as being related to both adsorption and possible denaturation on surfaces. The criticality of biomolecule adsorption in the context of microarrays and microfluidics devices will increase with the advancement of proteomics that probes the functionality of proteins, which are much more responsive to surfaces than DNA - the focal biomolecule of genomics. Anticipating this development, the present contribution proposes the establishment of a biomolecular descriptors database, which could be the starting point for a depositary of data and a source of validation for predictive models for adsorption and denaturation.© (2002) COPYRIGHT SPIE--The International Society for Optical Engineering.
