    This study introduces a simple, rapid method for preparing free cells for critical point drying. The technique involves dehydrating cells in suspension before CO2 drying, improving sample handling for microscopy.

    Area of Science:

    • Cell biology
    • Microscopy techniques
    • Sample preparation

    Background:

    • Critical point drying is a standard method for preserving cell structure.
    • Handling free-floating cells for critical point drying can be challenging.
    • Traditional methods may be time-consuming or lead to sample loss.

    Purpose of the Study:

    • To develop a simplified and efficient method for preparing free cells for critical point drying.
    • To improve the ease of handling suspended cells during the critical point drying process.

    Main Methods:

    • Cells were dehydrated while in suspension.
    • Dehydrated cells were mounted on double-coated tape on a specimen stub.
    • Samples were subsequently dried using carbon dioxide (CO2).
