The application discloses a preparation method of a europium-doped germanate red luminescent material, and is used for preparing a material with a chemical general formula of (0.025<=<=0.1). The method comprises the following steps: sodium carbonate, calcium carbonate, germanium dioxide and europium sesquioxide are weighed according to a metering ratio, wet grinding is carried out in a garnet mortar with anhydrous ethanol as a medium for 1-2 hours, and natural air drying is carried out; the dried powder is loaded into a corundum crucible and placed in a tube furnace, a solid phase reaction is carried out under an air atmosphere, the temperature is raised to 850 DEG C at a speed of 5 DEG C / min, and the temperature is kept for 6-8 hours; after the calcination is completed, the heating power is turned off, the product is naturally cooled to room temperature along with the furnace, and crushing and grinding are carried out to obtain the material. Through optimization of wet grinding and temperature control calcination and cooling parameters, the material powder agglomeration is avoided, and technical problems such as easy appearance of derived impurities in the synthesized product, low crystallinity and existence of residual stress in the crystal are solved.

The application discloses a kind of in-vivo cell patch clamp operation method based on electrode resistance guide, steps are as follows: first, the theoretical model of microtubule electrode resistance and the distance between nozzle-cell surface is established, and the key parameters of model are calibrated and verified using finite element simulation;Then, based on the theoretical model combined with transverse scanning, the dynamic three-dimensional positioning of cell is realized;Based on the target cell position information obtained by real-time positioning, a dynamic cell opposite grabbing strategy is proposed, so that the microtubule electrode contacts the cell at the farthest point of cell jumping, thereby maximizing the residence time after contact and promoting the formation of high resistance seal;Finally, based on the above, an electrode resistance guided robotic in-vivo neural cell patch clamp operation process is established.The application improves the degree of automation, positioning accuracy and high resistance seal success rate of in-vivo dynamic cell patch clamp operation.
