The key technology of Patient Derived Tumor Spheroids (PDTS) is to create an in-vitro patient tumor microenvironmenttumor-like properties, furthermore, predict various cancer antidrug effectiveness to each patient via the high-throughputhigh-quality cell viability detectionbiomarker analysis. Therefore, this project established several technologies including extracellular matrix fabrication, bioink design, cell population identification,tumor physiological environment for the upon goal.

We based on ion trap for mass filter so that ultra-high vacuum is not needed to reduce the weightsize. We took frequency scanning to increase our mass range by 10,000,000,000. We used LED as LC detector to reduce sizecost. Therefore, we not only made a portable device but also a device with many special advantages in technology. An advanced analytical lab can become mobile to easily reach anywhere which needs in-situreal-time analysis by our inventions.
