    摘要: An apparatus and a method for changing optical tweezers are provided. The apparatus includes a diffractive optical element (DOE), a mask unit and an objective lens. The DOE includes a plurality of phase delay patterns. The mask unit includes a plurality of mask patterns that correspond to the phase delay patterns, respectively, wherein at least a portion of the mask patterns are complementary. A laser beam passing through each phase diffractive pattern correspondingly passes through each mask pattern to generate a compound diffractive pattern. The objective lens receives the compound diffractive pattern and focuses it on an examining object to form an optical tweezers.

    摘要: An apparatus for driving a fluid includes a substrate, at least one electrode group and a controlling unit. The substrate has at least one plane. The electrode group is disposed on the substrate and includes a first electrode, a second electrode and a third electrode. A projecting position of the second electrode on the plane is disposed between that of the first electrode and that of the third electrode. The controlling unit electrically connected to electrode group is for driving the first to third electrodes. When the controlling unit drives the first to third electrodes to make the first and third electrodes have opposite polarities and to make the second and third electrodes have the same polarity, an electric field produced by the electrode group enables the fluid on the substrate to flow from the first electrode to the third electrode.

    摘要: A microfluidic control apparatus and operating method thereof. The microfluidic control apparatus includes a photoconductive material layer and a flow passage. When a light with a specific optical pattern is emitted toward the photoconductive material layer, at least three virtual electrodes are formed on the photoconductive material layer according to the specific optical pattern. The at least three virtual electrodes include a first virtual electrode, a second virtual electrode and a third virtual electrode disposed beside the first virtual electrode. There is a specific proportion among a distance between first virtual electrode and third virtual electrode, a width of first virtual electrode, a distance between first virtual electrode and second virtual electrode, and a width of second virtual electrode. When the specific optical pattern changes, the at least three virtual electrodes also change to generate an electro-osmotic force to control the moving state of a microfluid in a flow passage.

    摘要: A bubble micro-pump includes a first component, a second component and a bubble-generating unit. The first component includes a flow path having a first area and a second area. The second component above the first component has a first roughness surface and a second roughness surface. The first roughness surface opposite the first area has a first roughness factor, and the second roughness surface opposite the second area has a second roughness factor smaller than the first roughness factor. The bubble-generating unit on the first component generates bubble in the first area and the second area when a fluid fills the vacancy between the first component and the second component. Due to the difference in roughness factor, the backfilling velocity of the fluid in the first area is faster than that in the second area when the bubble starts to vanish, such that the fluid is driven to flow.

    摘要: An optical tweezers lifting apparatus is provided. The optical tweezers lifting apparatus includes an optical tweezers and a particle-lifting device. The particle-lifting device includes a substrate and a plurality of electrodes that are disposed on the bottom of a flow path in the substrate. When a dielectrophoresis (DEP) solution with a plurality of floating particles is conducted into the flow path and upon those electrodes and a voltage is applied to these electrodes, these particles would be driven by a negative DEP force to move upward to a specific depth in the flow path. Meanwhile, the optical tweezers of the apparatus is selectively focused at the specific depth in the flow path.
