Tapping atomic force microscope with phase or frequency detection
InactiveUSRE36488E1High resolutionHigh sensitivityMaterial analysis using wave/particle radiationBeam/ray focussing/reflecting arrangementsPhysicsMicroscope
An atomic force microscope in which a probe tip is oscillated at a resonant frequency and at amplitude setpoint and scanned across the surface of a sample, which may include an adsorbed water layer on its surface, at constant amplitude in intermittent contact with the sample and changes in phase or in resonant frequency of the oscillating are measured to determine adhesion between the probe tip and the sample. The setpoint amplitude of oscillation of the probe is greater than 10 nm to assure that the energy in the lever arm is much higher than that lost in each cycle by striking the sample surface, thereby to avoid sticking of the probe tip to the sample surface. In one embodiment the probe tip is coated with an antibody or an antigen to locate corresponding antigens or antibodies on the sample as a function of detected variation in phase or frequency. In another embodiment, the frequency of oscillation of the probe tip is modulated and relative changes in phase of the oscillating probe tip observed in order to measure the damping of the oscillation due to the intermittent or constant tapping of the surface by the tip. In a further embodiment, the slope of the phase versus frequency curve is determined and outputted during translating of the oscillating probe. Force dependent sample characteristics are determined by obtaining data at different tapping amplitude setpoints and comparing the data obtained at the different tapping amplitude setpoints.

Metal container
A metal container body 1 comprises a base and a generally cylindrical side wall 3. The top edge of the cylindrical side wall is rolled over to form a hollow annular bead 5 surrounding the upper open end of the container body and a notch 6 is formed at a circumferential point in the annular bead. The container body is for use with a releasable closure 2 formed with an end wall 7 and a depending skirt 8 and having an annular layer of sealing material 9 provided on the inside of the end wall adjacent the skirt. When the closure is pressed onto the container body, the annular bead engages the annular layer of sealing material and some of that material extends into the notch 6. The closure is held on the container only by the partial vacuum formed therein during processing of a food product in the container. After processing, the user opens the container by rotating the closure. Sealing material in the notch forces the closure to lift off from the container to break the seal and release the closure.
