To provide an improved method to prepare cell-attached slides. Methods Cellattached slides were prepared by routine method and self-made device, and the difference between the two methods were compared by observing the cell growth after HE staining. Three kinds of interventions were given to the same cell-attached slide to test the application in making different interventions cell-attached slide of the device. Three kinds of cells were planted in the same slide to test the application in making integrated cell-attached slides of the device. Results Our device simplified the preparation of cell-attached slides. Cells grown on the glass and never showed pollution or growth restriction, given different interventions or planted different cells at the same time without interaction. Conclusions The new method simplifies the processes of preparation cell-attached slides, and the slides made by our device satisfies the experiment demands of all kinds of cells staining, makes it as a more effective method than before.
