A non-aggregated and tumour-associated macrophage-targeted photosensitiser for photodynamic therapy: a novel zinc(<scp>ii</scp>) phthalocyanine containing octa-sulphonates
A novel non-aggregated zinc(ii) phthalocyanine bearing octa-sulphonates has been prepared which exhibits specific affinity to macrophages via the scavenger receptor-A, and can selectively accumulate in tumour site.
