通过真空辅助吸附剂提取从人类相关样品中捕获活性产生的微生物挥发性有机化合物

Executive Industry Relevance

Disentangling the microbial origins of volatile organic compounds (VOCs) in human-associated samples is critical for advancing metabolic biomarker discovery and understanding host-microbe interactions. The integration of vacuum-assisted sorbent extraction (VASE) with stable isotope probing enables precise attribution of VOCs to active microbial metabolism, supporting translational research and early biomarker validation. This workflow enhances predictive confidence in identifying disease-relevant metabolic signatures and informs risk-adjusted portfolio decisions in biopharma R&D.
