Life in non-aqueous solutions

Posted on September 16, 2008 by Aschwin de Wolf

Can life exist without water? This is one of the questions that fascinates astrobiologists. The behavior of biomolecules in non-aqueous solutions is also of interest to cryobiologists and cryoenzymologists. Ice formation below zero degrees Celsius can be prevented by high … Continue reading →

Cryoenzymology and cryoprotectant toxicity

Posted on September 4, 2008 by Aschwin de Wolf

The major limiting obstacle to reversible cryopreservation of complex organs is cryoprotectant toxicity. Elimination of ice formation through vitrification requires high concentrations of cryoprotective agents. These high concentrations of cryoprotectants can be toxic to tissues. Over the years, major advances … Continue reading →
