Flexible Electrodes: Paper‐Based Electrodes for Flexible Energy Storage Devices (Adv. Sci. 7/2017)

Devices based on intelligent biopolymers for oral protein delivery.

The primary goal of bioadhesive controlled drug delivery is to localize a delivery device within the body to enhance the drug absorption process in a site-specific manner. An important contributor to good adhesion is the presence of molecular adhesion promoters such as polymer-tethered structure (e.g., poly(ethylene glycol) chains grafted to crosslinked networks) or even linear chains which are...
