Surface immobilized molecules play a crucial role in applied as well as in basic research. They can be found in DNA or protein-array as well as in cell-migration or biochemical interaction experiments. Especially for proteins the immobilization can critically affect molecule accessibility and activity. In this work two essential aspects of protein immobilization were investigated: the identification of suitable surface functionalization by two array approaches and the generation of laterally structured gray scale protein patterns by projection lithography. In proof-of-concept experiments a new strategy to create an array of different, neighboring functionalizations on the same surface was successfully tested. In "mechanical protection" inert plungers were applied to protect distinct surface areas from the surface functionalization reagents and allowed a selective modification of individual regions in serial reactions. In a particle based alternative approach a high spot density surface array was fabricated using functionalized, polyvinyl acetate, melamine and silicon oxide-based particles. The in situ encoded bead-based array (IEBA) allowed the study of immobilization conditions and the effect of protein adhesion. For the reliable and fast analysis of array-images with several thousand individual particles a custom open-source evaluation software was developed. To create protein patterns a custom-built projection lithography device was utilized to generate high definition protein patterns. Patterning conditions were optimized with respect to deposition speed and signal to noise ratio while retaining a biocompatible process flow. The established technology provides protein patterns with great control over the deposited surface density, patterns were transferred within seconds to minutes to functionalized glass slides. To obtain three-dimensional, surface-functionalized surfaces this approach was transferred to thin polymer films. The substrates were demonstrated to be biocompatible with mouse fibroblasts. These surfaces allow a novel level of control addressing both the chemical surrounding and the shape of a cell microenvironment.

Biomolecules and cells are critical components of biosensors and biomaterials, but in order to function in an artificial environment, they must be immobilized in a manner that does not affect their interaction with target analytes. Biosensors demonstrate that we can harness the incrediblefunctions of living molecules and cells for our own purposes and are therefore at the forefront of technology. Moreover the applications of immobilized biomolecules and cells are expected to expand far beyond biosensor applications and indeed are already used for pharmaceutical production andtesting. Biomaterials will become increasing common as they are being developed into toxic filters, artificial organs, and even silicon chips. This book provides a selection of methods for the immobilization of biomolecules and cells on a variety of surface with different geometries and chemistriesso that they retain their function and guidelines on which method to use. Also included are the analytical techniques to measure the functionality of immobilized biomolecules. All the protocols have been tried and validated by the authors. Immobilized Biomolecules in Analysis: A Practical Approachis an invaluable guide to all researchers in the fields of biosensors and biomaterials. Research in biosensors is carried out in a wide variety of fields including biochemistry, chemistry, engineering, laboratory medicine, environmental and defence research. The protocols are written so that anextensive prior knowledge of biochemistry is not required to use them.
