The cell culture dishes have a thermosensitive surface, which is coated with a nanopolymer. When the temperature decreases from 37°C to 4°C, the thermosensitive surface gradually changes from slightly hydrophobic to hydrophilic, allowing for the harvest of adherent cells without trypsin. By using this gentle collection method, the cells are safe from injuries caused by trypsin or scrapers, thus preserving high viability and the integrity of surface receptors and cell antigens. This operation enables cells to be harvested without damage for subculturing.
