    Abstract: The present invention discloses a flexible 3D microprobe structure, which comprises at least one probe, a base and a hinge portion. The probe is connected to the base via the hinge portion. The probe forms a bend angle with respect to a normal of the base by attracting the probe through an electrostatic force to make the hinge portion bend with respect to the base, and thus to form a 3D structure having the bend angle. The probe, the base and the hinge portion are made of a flexible polymeric material to reduce the inflammation response of creatures. Further, a fixing element is used to enhance the structural strength of the flexible 3D microprobe structure.

  • Patent number: 8278629
    Abstract: Live-cell imaging chambers are used in a wide range of cell biology research. Recently, chambers capable of taking high-resolution and time-lapse images of live cells have been developed and become commercially available. However, since most of these chambers are designed to maintain a thermally stable environment for the cells under study, it is usually very difficult to use them to study temperature-dependent cellular events. The present invention provides a live-cell observation equipment for a non light-transmitting microscope to study temperature-dependent events and method thereof.
