• resolution and near-field optical images were obtained in liquid environments [15][18][19]. For some applications, it is required that the tip is not perpendicular to the prong of the tuning fork [20][21]. The advantage of a qPlus sensor with a long tilted tip (Figure 1) is that forces in multiple directions
