Removing Time from the Equation
X-Therma enables the robust preservation of cells, tissues, organs, and other biologics by leveraging our proprietary peptoid. The peptoid inhibits lethal ice crystals, allowing long-term sub-zero storage of biological materials while maintaining unparalleled functionality and viability.

How it Began
When she was 8 years old, Xiaoxi’s beloved grandfather passed away. If he had received a donor liver, he would have had more time to spend with loved ones.
Xiaoxi has since dedicated her life to finding a solution that increases organ availability. In 2014 she obtained her doctorate in medicinal chemistry from SUNY-Buffalo. Soon after, she established X-Therma to bring her vision of eradicating organ waitlists to life.
