Berries polyphenols: Nano-delivery systems to improve their potential in cancer therapy

Berries bioactive compounds, specially polyphenols, have been widely recognized for their chemopreventive and chemotherapeutic properties. However, most of them struggle with chemical instability, low solubility, extensive metabolism and consequently poor bioavailability, which limit their clinical use. An effective strategy to overcome such problems consists of the nano-delivery systems. In the present review, the progress made in utilization of nano-carriers for berries polyphenols administration either alone or in combination with chemotherapeutic drugs have been summarized.
