We report microgel beads with diameters of ca. 800 nm based on interpenetrating networks a low-molecular-weight gelator and polymer gelator, demonstrate their use as heparin delivery vehicles to enhance stem cell growth.

BACKGROUND The hydrogel based system is found to be rarely reported for the delivery of hydrophobic drug due to the incompatibility of hydrophilicity of the polymer network and the hydrophobicity of drug. This problem can be solved by preparing semi-interpenetrating network of cross-linked polymer for tuning the hydrophilicity so as to entrap the hydrophobic drugs. The current study is to devel...

A facile route for the fabrication of surface-attached hydrogel thin films with well-controlled chemistry and tailored architecture on wide range of thickness from nanometers to micrometers is reported. The synthesis, which consists in cross-linking and grafting the preformed and ene-reactive polymer chains through thiol-ene click chemistry, has the main advantage of being well-controlled witho...

A multi-source/component spray coating process to fabricate the photoactive layers in polymer solar cells is demonstrated. Well-defined domains consisting of polymer:fullerene heterojunctions are constructed in ambient conditions using an alternating spray deposition method. This approach preserves the integrity of the layer morphology while forming an interpenetrating donor (D)/acceptor (A) ne...

• Interpenetrating polymer network (IPN) hydrogels are prepared in mild conditions. Stable 3D patterns were successfully produced through direct laser write (DLW) technology. 4D printing could be achieved even presence of silver nanoparticles (AgNPs) The new materials exhibit very interesting antibacterial activities. In the past few decades, interpenetrating have attracted huge attention due t...
