The Material Measurement Laboratory at NIST conducts research to develop new measurement methods and standards for the reliability of laboratory-grown cells and tissues. Specifically, the interactions between implantable materials and the body is of interest. To address this issue we have developed a new single-cell force spectroscopy (SCFS) capability by atomic force microscopy (AFM). This technique provides highly quantitative measurements of adhesive interactions in terms of adhesive force, energy, and kinetics. Two possible systems are (1) Measuring cell adhesive interactions to the extracellular matrix (ECM), which are essential to many physiological and pathological processes. (2) Understanding of initial pathogenic bacteria adhesion to host surfaces is a prerequisite to the development of defense mechanisms for the host surface.
