    A novel, cost-effective device enables high-magnification scanning of neural tissue cultures. This microscope system allows extensive area examination without disturbing microelectrodes, preserving experimental integrity.

    Area of Science:

    • Neuroscience
    • Microscopy
    • Biotechnology

    Background:

    • Investigating neural tissue requires precise microelectrode placement.
    • Maintaining electrode integrity during microscopic examination is challenging.

    Purpose of the Study:

    • To develop an affordable device for scanning large areas of neural cultures.
    • To enable microscopic observation without disrupting microelectrode placement.

    Main Methods:

    • Designed a removable inverted phase-contrast microscope system.
    • Integrated a rigid metallic framework to secure the microscope stage.
    • Utilized a sliding optical component on a mirror and ball-bearing base for smooth movement.
    • Employed original rack and pinion controls for focusing and scanning.
