Ultra-microinjection detection and control device based on lensless imaging and method thereof
The present invention provides an ultra-microinjection detection and control device based on lensless imaging and a method thereof. A lensless optical liquid level sensor is used to measure a change of a liquid level in an injection needle. A microinjection control unit is used to track the change of the liquid level and correct an injection pressure of the injection pump. Transmitted light generated by a parallel light source passes through a transparent glass tube of the injection needle. Then the transmitted light passes through a light filtering film to reduce the intensity of the parallel light source to a photosensitivity range of a micro linear array image sensor chip. Finally, the transmitted light enters the micro linear array image sensor chip, so that the micro linear array image sensor chip measures the change of the liquid level in the injection needle.
Sampling Device And Cell Culture System
A cell culturing system configured to move a liquid sample from a cell culturing device to a sampling channel via a sample introduction channel. The sampling device includes a sampling channel having a main-mechanism-side pump disposed between a cleaning solution storage unit and the sample introduction channel and is configured to allow a cleaning solution to flow to a detection unit. The sample introduction channel includes an introduction-mechanism-side pump that is configured to allow the sample to flow from the sample introduction channel to the detection unit.
Sampling Method
A sampling device includes a sampling channel, a detection unit and a sample introduction channel. A cell culturing device or the sample introduction channel includes an aseptic filter in a section before the sampling channel. A sampling method includes a sampling step for introducing the sample from the culturing device and detecting the sample by the detection unit and an adhering substance removal step for removing an adhering substance adhering to the aseptic filter by allowing a fluid to flow from the sampling channel to the sample introduction channel.
SYSTEM AND METHOD FOR DRAINING A FLEXIBLE BIOPROCESSING BAG
An apparatus for draining a bioreactor vessel includes a tubular body portion having an interior passageway, and at least one aperture in the tubular body portion providing for fluid communication with the interior passageway, the tubular body portion being configured for positioning at a bottom of a vessel, and a suction tube having a first end configured for fluid coupling with the tubular body portion, and a second end configured for fluid coupling with a port in a sidewall of the vessel.
Method for three-dimensional replication of a biological tissue
A method for three-dimensional reproduction of a biological tissue in the framework of tissue engineering. A substrate is provided and primary cells of a first cell type are deposited on the substrate. A first precursor of a substance adhering the cells is arranged on at least a selection of the primary cells of the first cell type. A second precursor of the substance adhering the cells is arranged in a locally targeted manner on the selection of primary cells of the first cell type according to a structure formed by cells of the first cell type in the tissue to be reproduced. The first precursor and the second precursor react with each other to form the substance adhering the cells, which substance adheres the selection of the primary cells of the first cell type according to the structure formed by the cells of the first cell type in the tissue to be reproduced.
Automated cell culturing and harvesting device
An automated cell culturing device, which expands, detaches and prepares cells, ready to be implanted in vivo is disclosed. The device is composed by a multi-layered cell culture chamber, a cell preparation chamber, and critical parameters control units which automatically drive the cell culture medium circulation, change and refill. The device according to the invention is characterized in that all the components contacting cells and culture medium constitute a totally disposable “cartridge” in order to avoid cross-contamination and improve safety. The device is particularly useful for expanding and preparing mesenchymal stem cells for osteoarthritis (OA) therapy, and for other cell based therapies in mammals.
METHOD FOR PREPARING DROPLETS USING MICROFLUIDIC CHIP SYSTEM
A method for preparing droplets using a microfluidic chip system is provided. The microfluidic chip system includes a droplet generation device, a power generation device, a collection bottle, a connection device, and a preparation platform, the droplet generation device includes a chip body, the chip body defines a continuous phase inlet for receiving a continuous phase and a dispersed phase inlet for receiving a dispersed phase. The power generation device is activated to form a pressure difference among the collection bottle, the connection device, and the chip body, wherein the pressure difference promotes the dispersed phase and the continuous phase to converge and flow into the collection bottle in form of the droplets.
