利用受激拉曼散射显微镜检测细菌抗生素敏感性

Executive Industry Relevance

Rapid detection of bacterial antibiotic susceptibility is critical for early-stage anti-infective discovery and translational research. Stimulated Raman scattering (SRS) microscopy enables quantitative, single-cell assessment of bacterial viability by measuring deuterium-labeled metabolic activity, supporting predictive confidence in antimicrobial screening. This approach accelerates decision-making at key inflection points in anti-infective portfolio development.
