  • Publication number: 20170121664
    Abstract: A cell separation device imparts vibration to a cell culture film having a front surface to which cells adhere, from a rear surface side of the film, and consequently separates the cells from the film. The device includes an ultrasonic probe having an ultrasonically-vibrating vibrator, a frame disposed to surround the vibrator and a first detection part configured to detect a force applied to the frame in a specified direction. The vibrator selectively imparts ultrasonic vibration to specified cells adhering to the front surface of the film. Based on a detection result obtained by the first detection part, the frame is pushed until the force applied from the rear surface of the film to the frame reaches a specified magnitude. Thereafter, the vibrator ultrasonically vibrates in a state in which the frame makes contact with the rear surface of the film.

    Abstract: Provided is a method for producing a filtration filter capable of purifying with high accuracy and largely improving filtration efficiency. A flow path forming film is formed on a substrate. A plurality of grooves is formed on the flow path forming film along a surface of the substrate by etching. The grooves are filled with a sacrificial film. The flow path forming film and the sacrificial film are planarized by polishing the sacrificial film. A flow path sealing film is formed on the planarized flow path forming film and sacrificial film. An inlet hole and an outlet hole are formed through the substrate and the flow path sealing film, respectively, so that parts of the sacrificial film are exposed through the inlet hole and the outlet hole. The sacrificial film is removed using the inlet hole and the outlet hole and the filtration flow paths are formed by the grooves.
