Atomic force microscopy characterizes diamond surfaces for sensing applications

Gary Boas

Researchers are working to develop cell-based sensors on diamond because the material could serve as a signal transduction system for biological or chemical sensing. The biocompatibility of the material is not fully understood, however, especially with respect to its surface chemistry and topography. Studies have shown that its surface properties can be made hydrophobic or hydrophilic, which is important to cellular adhesion. However, the surface adhesion properties of diamond have yet to be characterized in detail. As suggested by these fluorescence micrographs, the weakest cellular...Read full article
