The present invention relates to a dual-arm clamping type holder for transmission electron microscopy grids and preparation method thereof. The preparation method comprises: firstly manufacturing a frame with two adjacent arms located on a same plane and have a clamping structure by a hard material; then putting the frame in a molten adhering liquid so that the frame is dipped with the adhering liquid; and finally, taking out the frame dipped with the adhering liquid, and waiting for the adhering liquid to solidify into adhering layers along the arms. The dual-arm clamping type holder manufactured by the method of the present invention comprises a frame and adhering layers; and the adhering layers adhere to the inner sides of the clamping structure between the two adjacent arms of the frame.

The present invention relates to a magnetic holder for immunoelectron microscopy grids. The holder comprises a frame, a magnet and a hydrophobic layer. The device can use a magnetic force to simultaneously attach the outer rings of nickel grids to the frame, so that a batch operation (such as rinsing, immunolabeling and dyeing) of the nickel grids can be realized. In addition, due to the hydrophobic effect of the hydrophobic layer, the holder can reduce the amount of the liquid carried by the nickel grids in the process of continuously transferring the nickel grids between different types of liquids to almost zero. Compared with the prior art, the magnetic holder effectively reduces the probability of cross-contamination between reagents.
