文摘
- •
There are two types of sites on PNIPAM molecules for the binding of piceatannol.
- •
The number of binding sites and the binding strength show pH- and temperature-responsiveness.
- •
The maximum free concentration of piceatannol occurs at 25 °C and pH 6.2.
- •
Piceatannol may be controllably released from PNIPAM by adjusting the pH and temperature of the medium.
