  • Patent number: 9588136
    Abstract: An improved mode of AFM imaging (Peak Force Tapping (PFT) Mode) uses force as the feedback variable to reduce tip-sample interaction forces while maintaining scan speeds achievable by all existing AFM operating modes. Sample imaging and mechanical property mapping are achieved with improved resolution and high sample throughput, with the mode workable across varying environments, including gaseous, fluidic and vacuum.

  • Publication number: 20160274144
    Abstract: Methods and apparatuses are provided for automatically controlling and stabilizing aspects of a scanning probe microscope (SPM), such as an atomic force microscope (AFM), using Peak Force Tapping (PFT) Mode. In an embodiment, a controller automatically controls periodic motion of a probe relative to a sample in response to a substantially instantaneous force determined and automatically controls a gain in a feedback loop. A gain control circuit automatically tunes a gain based on separation distances between a probe and a sample to facilitate stability. Accordingly, instability onset is quickly and accurately determined during scanning, thereby eliminating the need of expert user tuning of gains during operation.

  • Patent number: 9433709
    Abstract: An interventional medical device and manufacturing method thereof. The interventional medical device comprises: a stent body (1); a surface of the stent body (1) being provided with a drug releasing structure (3), and drug in the drug releasing structure (3) being drug for suppressing proliferation of adventitial fibroblasts and a drug for suppressing proliferation of intimal and/or smooth muscle cells. In use, after interventional medical device is implanted into a human body, the drug for suppressing proliferation of adventitial fibroblasts carried thereon can promote the compensatory expansion of the vessel, and the drug for suppressing proliferation of intimal cells and/or smooth muscle cells carried thereon can suppress intimal proliferation of the vessel. The combination of the two kinds of drugs greatly reduces the occurrence rate of in-stent restenosis.
