Mechano- and Thermoresponsive Photoluminescent Supramolecular Polymer [PDF]

Journal of the American Chemical Society, 2017
Mechanoresponsive luminescent (MRL) materials change their emission color upon application of external forces. Many dyes with MRL behavior are known, but they normally do not display useful mechanical properties. Here, we introduce a new approach to overcome this problem, which relies on combining MRL compounds with the concept of supramolecular ...

Thermoresponsive polymer nanocarriers for biomedical applications [PDF]

Advanced Drug Delivery Reviews, 2019
Polymer nanocarriers allow drug encapsulation leading to fragile molecule protection from early degradation/metabolization, increased solubility of poorly soluble drugs and improved plasmatic half-life. However, efficiently controlling the drug release from nanocarriers is still challenging.
