A Smart Polysaccharide/Drug Conjugate for Photodynamic Therapy

Sharper image: A newly developed polysaccharide/drug conjugate (see picture) responds to changes in pH value and was shown to penetrate HeLa tumors in mice as determined by fluorescence imaging. It has the potential to be used in photodynamic therapy, thereby targeting the tumor while having no detrimental effects on the surrounding tissue.
