The MFP-3D-BIO provides the highest sensitivity and most accurate images and measurements possible on an inverted optical platform. The NPS™ closed loop nanopositioning sensors on all three axes ensure distortion-free images on samples as small as proteins and as large as cells - in both air and liquid. The MFP-3D measures the cantilever deflection to better than 20pm (8pm typical) without artifacts, making the MFP-3D ideal for force measurements such as unfolding single molecules or probing cell mechanics.
