AI Technical Summary

Technical Problem

Existing technologies cannot effectively distinguish between the three-dimensional posture distortion of coded microspheres and fluorescence signal fluctuations caused by self-shielding effects in dynamic flow environments, resulting in high dispersion of detection results for low-abundance samples, which cannot meet the requirements of high repeatability and high accuracy.

Method used

By inversely mapping the spatial distribution topology of feature points to the three-dimensional attitude representation vector, and combining the feature point diffusion function and channel intermodulation matrix, we can achieve accurate identification and signal restoration of random spatial rotation of coded microspheres, and eliminate spectral cross-interference and sensor nonlinear response distortion.

Benefits of technology

It significantly improves the signal restoration capability of exosome detection, reduces systematic bias, and ensures the accuracy and repeatability of high-fidelity molecular distribution information.
