无毒高效的低温保护剂

Recently, it has been shown, that it is possible to freeze and unfreeze a mammalian brain, preserving its micro-structure, including all synaptic connections. However, it was done using glutaraldehyde and ethylene glycol (link) which are toxic.

If a non-toxic material of comparable efficacy would be found, perhaps this would ultimately enable people to preserve large organs, and even use suspended animation to time-travel to the future.
