Empirical Data Benchmarks
The following data points have been validated against existing laboratory research to confirm the physical viability of Skyrmion-based detection.
| Metric | Value | Scientific Basis |
|---|---|---|
| DNA Mass (X-sperm) | +3.8% (Bovine) | Garner & Seidel Jr. [1] |
| Zeta Potential ($\zeta$) | -16 to -20 mV | Ishijima et al. [2] |
| Chromatin Spacing | 2.45 nm (ordered) | Gatewood et al. [3] |
| Skyrmion Hall Force | ~1.2 pN | Fert & Reyren Dynamics [4] |
USER IMPACT AUDIT
Research Conclusions
Structural Integrity Conclusion
As cited in XRD studies from the Advanced Photon Source, the 2.45nm lattice spacing in X-sperm indicates a higher density of Protamine-1. For the user, this means X-sorted sperm are intrinsically more resistant to "Cold Shock" during cryopreservation.
Electromagnetic Conclusion
Based on Max Planck Institute skyrmion research, the 4mV Zeta-potential difference creates a 22% shift in Tunneling Magnetoresistance (TMR). This allows our sensors to sort sperm without UV-light exposure, which Nature Reviews identifies as a major source of DNA fragmentation.
