Nature provides many examples of the benefits of nanoscopic surface structures in areas of adhesion and antifouling. Herein, the design, fabrication, and characterization of liquid crystal elastomer (LCE) films are presented with nanowire surface structures that exhibit tunable stimuli-responsive deformations and enhanced adhesion properties. The LCE films are shown to curl toward the side with the nanowires when stimulated by heat or organic solvent vapors.

Article Synopsis
- Innovation through process automation is improving performance in various fields, but recognizing details in images remains challenging due to variations and specific conditions.
- Artificial intelligence simplifies this issue by using algorithms that detect specific pixels for image segmentation, utilizing modules like Efficient Sub-Pixel Convolutional Neural Networks and U-Net for effective capillary structure identification.
- The developed model demonstrated strong performance across multiple datasets, achieving high metrics (PSNR of 37.92 and SSIM of 0.9219), and showcased its complexity in processing with varied execution times for its enhancement, segmentation, and masking modules.

T7 RNA Polymerase (RNAP) is a widely used enzyme with recent applications in the production of RNA vaccines. For over 50 years denaturing sequencing gels have been used as key analysis tools for probing the nucleotide addition mechanisms of T7 RNAP and other polymerases. However, sequencing gels are low-throughput limiting their utility for comprehensive enzyme analysis.

Article Synopsis
- Conventional drug delivery often requires high doses, leading to significant side effects, whereas targeted delivery methods using nanoparticles have limited efficacy in reaching their intended sites.
- This study proposes the use of deformable microrobots made from hydrogel capsules, which can navigate challenging environments to deliver drugs more effectively at localized sites, improving biocompatibility and responsiveness.
- A novel, cost-effective method for fabricating these microrobots is introduced, using a gelation process with varying calcium ion concentrations to create functional core-shell structures for potential applications in drug delivery and microrobotics.
