This study presents an ultraviolet (UV)-curable polymer which is applicable to open-access microfluidic platforms. The UV-curable polymer was prepared by mixing trimethylolpropane triacrylate (TMPTA), 1,6-hexanediol diacrylate (HDDA), polyethylene glycol-diacrylate (PEG-DA), and Irgacure 184. The polymer resin is optically transparent before and after UV-assisted curing and showed good biocompatibility when culturing multiple types of cells on the nanopatterned polymer substrate. The polymer has good adhesion with poly(dimethylsiloxane) (PDMS) even under large deformation and showed a low swelling ratio when exposed to water, suggesting a possibility to be used as a substrate for an organ on a chip. Furthermore, because the polymers have controllable hydrolysis ability depending on the composition, long-term 3D cell culture and subsequent biological analysis with harvested cells are possible. The self-detachable synthesized UV-curable polymer may help the advancement of biomedical studies using in vitro cell culture.

Scalable fabrication of high-quality micro/nanoscale spherical-cap structures is significant for applications spanning optical devices, electronics, bio-devices, and sensors. Existing top-down and bottom-up fabrication methods are often constrained by material compatibility, thereby unable to provide the full diameter spectrum of uniformly, and high-quality structures. Here, we present what we believe to be a novel approach that combines electrohydrodynamic jet printing with Plateau-Rayleigh instability (PRI-EHDP) for generic, scalable, and precisely controllable fabrication of micro/nano-optical devices.

Silicone medical devices are widely used as various medical devices due to their excellent advantages when compared with petroleum-derived polymers. Thrombosis and bacterial infections are two vital challenges of blood-contacting silicone devices. The traditional strategies used for contact antibacterial silicone typically facilitate thrombosis due to electrostatic interactions.

E-textile technologies are quickly advancing, but the power supply is still one of the limiting factors, particularly for those integrated into textiles. There is a pressing demand for flexible textile-based microdevices capable of storing and supplying energy. In this work, it is demonstrated that laser ablation (LA) can be conveniently used to achieve patterned thin film electrodes with interdigitated configuration on TPU-coated cotton fabric to produce textile-based energy storage units.

Renewable and green energy technologies, particularly the improvement of solar panel efficiency, have gained considerable attention in academic and industrial communities. However, long-term exposure to soiling can lead to substantial reduction in the energy generation capacity of photovoltaic systems. Here, hyperbranched polyurethane acrylate (PHBA) was synthesized using hydroxyl-terminated hyperbranched polyester as a core component.
