Soft Poly(N-vinylcaprolactam) Based Aqueous Particles

Acta Chimica Slovenica, 2022
Soft nanoparticles are an important class of material with potential to be used as carriers of active compounds. Swollen, penetrable particles can act as a host for the active ingredients and provide stability, stimuli-responsiveness and recyclability ...

Pharmacokinetics of Intramuscularly Administered Thermoresponsive Polymers

Advanced Healthcare Materials, 2022
AbstractAqueous solutions of some polymers exhibit a lower critical solution temperature (LCST); that is, they form phase‐separated aggregates when heated above a threshold temperature. Such polymers found many promising (bio)medical applications, including in situ thermogelling with controlled drug release, polymer‐supported radiotherapy ...

Lyophilization for Formulation Optimization of Drug-Loaded Thermoresponsive Polyelectrolyte Complex Nanogels from Functionalized Hyaluronic Acid

Pharmaceutics, 2023
The lyophilization of nanogels is practical not only for their long-term conservation but also for adjusting their concentration and dispersant type during reconstitution for different applications.

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.
