Core Technology

2 min readJun 7, 2022

Compared to other technologies currently available in the market, the exclusive technology of CancerFree Biotech is to isolate a very small number of circulating tumor cells that enter the bloodstream from in-situ tumors and increase the total number of circulating tumor cells through our exclusive cell culture technology.

◎ Ex Vivo Avatar (E.V.A.)

The first commercializable CDO culture system
We develop a Circulating Tumor Cell-Derived Organoid (CDO) culture system containing 3D scaffolds to facilitate tumor cell proliferation:

- 3D structure mimics in vivo extracellular matrix.
- Replicate in vivo environment for tumorigenesis.
- High efficacy: successful rate about 90%. (in 100+ cancer types).
- High efficiency: 1,000~100,000 folds proliferation within 4 weeks.
- Over 900 sucessful cases.
- 100 types of generic drugs can be tested.
