Ice by John Hawkhead

a deep understanding
of the chemistry of ice
cracks in our matrix

Ice as a Matrix

Ice, the frozen form of water, can act as a matrix or a medium to hold other substances in place. 

Applications:

• Cryopreservation: Ice matrices are used in cryopreservation techniques to freeze and preserve biological samples by embedding them in ice, which helps to minimize ice crystal formation and damage to the samples. 

• Material Science: Ice matrices can be used for encapsulating or embedding materials for research purposes, such as studying the properties of materials in a frozen state or for creating composite materials. 

• Protein Analysis: Ice matrices are used in techniques like IR-MALDI (Infrared Matrix-Assisted Laser Desorption/Ionization) to analyze proteins in frozen samples. 

• Film Production: Matrix-assisted pulsed laser evaporation (MAPLE) uses water ice as a matrix for producing thin films of materials like polyethylene glycol (PEG).
