Sugar-labeled and PEGylated (bio)degradable polymers intended for targeted drug delivery systems

► Controlled drug delivery systems are crucial to protect the drug and to allow it to reach the pathological area. ► Sugars as pilot molecules enable the targeting of tissues through sugar-receptor recognition. ► Better understanding of sugar/lectin interactions is possible by physico-chemical analysis. ► Development of strategies for the sugar-decoration of PEGylated degradable polymeric carriers is required for drug delivery systems.
