Chemical modifications to the surface of the probe may improve integration into host tissues by preventing sheath development, and may promote directed connections between the thin film electrodes (TFEs) and neurons. The used of positively charged molecules to promote adhesion of astrocytes onto silicon surfaces are examined. Double staining with acriflavin and diIC18 allowed visualization of cell nuclei, cell membranes, and the octadecyltrichlorosilane (OTS) background. Scanning laser confocal microscopy is used to collect three dimensional digital images. An automated cell counting program is used to localize the position of the OTS background to determine how many cells adhered to the charged pattern versus the unchanged background.
