The control of the physicochemical properties of surfaces in contact with biological systems represents a fundamental issue in many applications. In particular, advances in nanobiotechnology depend on the ability to fashion materials with precise control of feature dimension and functionality. This presentation focuses on issues of specific and non-specific binding and strategies being developed to control both. Examples of specific binding that enable investigation of cell function will be presented. The broader issue of non-specific binding and how it relates to fouling release will also be discussed in terms of surface structure. Both polar and non-polar polymer brush surfaces have been investigated and each type shows promise for release of specific biological systems. In particular, polymer brushes grown from silicon surfaces have been shown to be especially effective. The use of polymers brushes for control of cell-surface interactions will be discussed.
