Yucel and co-workers have developed a formulation consisting of non-fluorescent dye QC-1 conjugated albumin coupled with BODIPY-based fluorophore for PAI imaging of the lymphatic drainage in the regions from eyes to the neck region, which could be path breaking in theranostic imaging research as most of the metastasis originating from the head and neck cancers can be analyzed through the corresponding regional lymph nodes [142, 205]. The gene discussed is ALB; the disease is head and neck cancer.
