Antibody-Functionalized SERRS Nanoprobe Based Imaging: A Highly Sensitive Raman-imaging Technique to Detect Metastatic Ovarian Cancer In Vivo

Executive Industry Relevance

This SERRS nanoprobe imaging approach enables sensitive in vivo detection of metastatic ovarian cancer by distinguishing targeted binding from non-specific background through ratiometric spectral analysis. The technique supports early-stage target validation by providing quantitative, spatially resolved readouts of receptor engagement in disease-relevant microenvironments. Its capacity to differentiate cancerous tissue from visceral surfaces enhances predictive confidence in preclinical oncology models.
