Basilard BioTech’s SoloPore technology, compared to viral delivery. Credit: Basilard Biotech More What if you could cure cancer by re-engineering patients’ cells to better target and destroy their own tumors? With the advent of powerful new cellular engineering technologies, this is no longer the stuff of science fiction. In the past few years, these technologies
