미세 입자상 물질에 노출된 제브라피시 배아에서 다환 방향족 탄화수소를 검출하기 위한 변형된 QuEChERS-HPLC 방법

Executive Industry Relevance

Quantitative detection of polycyclic aromatic hydrocarbons (PAHs) in small, complex biological matrices is a critical challenge in early toxicology and environmental risk assessment workflows. The modified QuEChERS-HPLC method enables sensitive, reproducible measurement of internal PAH levels in zebrafish embryos, supporting mechanistic de-risking and predictive confidence in developmental toxicity studies. This capability strengthens translational continuity from environmental exposure models to preclinical safety evaluation in biopharma pipelines.
