ShareICE NUCLEATION AND FREEZING IN UNDERCOOLED CELLS.
Author(s) : FRANKS F.
Type of article: Article
Summary
DIFFERENTIAL SCANNING CALORIMETRY HAS BEEN EMPLOYED TO STUDY THE EFFECT OF COOLING ON A RANGE OF CELLS UNDER EXCLUSION OF EXTRACELLULAR ICE AND IN THE ABSENCE OF CHEMICAL CRYOPROTECTANTS. IN CONTRAST TO EARLIER REPORTS, ALL THE CELLS STUDIED WERE FOUND TO FREEZE AT TEMPERATURES ABOVE THAT INDICATED FOR HOMOGENEOUS NUCLEATION OF ICE IN UNDERCOOLED LIQUID WATER. POSSIBLE NUCLEATION MECHANISMS ARE DISCUSSED IN TERMS OF THE EXPERIMENTAL DATA AND THE CELL DIMENSIONS.
