While these properties of CNT have improved the performance and extended the capabilities of AFM in air [1], CNT tips can also be used in liquid environments to enable applications that were previously unachievable with conventional silicon and silicon nitride tips. Force microscopy of biological samples submerged in an aqueous liquid medium that mimics the specimen’s milieu in vivo can be enhanced by CNT AFM tips. CNT promotes less invasive force microscopy of biological specimens because CNT elasticity reduces the risk of damage to delicate, soft samples.

Force microscopy of biological samples submerged in an aqueous liquid medium that mimics the specimen’s milieu in vivo can be enhanced by CNT AFM tips. CNT promotes less invasive force microscopy of biological specimens because CNT elasticity reduces the risk of damage to delicate, soft samples. CNT’s vertical hydrophobic sidewalls minimize the influence of nonspecific adhesion forces on the tip. In addition, the high-aspect-ratio structure of CNT can potentially eliminate interfering fluid drive on the cantilever.

15b). 15c). In general, this filter will flatten the image, but sometimes, the peculiarities of the data require some extra procedures. For instance, the data used to illustrate this example is clearly divided in two main planes: the basal surface and the plane given by the polystyrene nanospheres. 13. Sometimes, raw data must be processed to reduce high-frequency noise or to enhance the edges of objects. This is done with low-pass or high-pass filters, respectively. High frequency noise can be removed by replacing the value of each image point by the average of next neighbors (nine data points).
