Summary: Optically anisotropic materials form through colloidal lithography were studied using SEM, confocal microscopy, and polarimetry. A hexagonal array mask made of sub-micron silica particles was created via Langmuir-Blodgett self-assembly, and the pattern was transferred onto silicon and glass substrates using ion beam etching. Gold films were then deposited onto the etched pillars to enhance optical properties. Polarimetric measurements showed that the etching directions influenced the linear birefringence and linear dichroism, with the chiroptical responses increasing with the angle of incidence.

Summary: This study introduces a convenient and fast method to fabricate steady ACA patterns using cationic monodisperse polystyrene microspheres and polybutyl acrylate nanoparticles. The mechanical stability of the colloidal array is enhanced by embedding PBA nanoparticles in PS microsphere voids, while still exhibiting bright angle-independent structural color when moderate PBA nanoparticles are introduced. Overall, this method shows promise as a potential substitute for traditional ink printing.

Summary: This strategy demonstrates a controllable method to fabricate polymeric nanowires with high throughput and low cost using thermal nanoimprint lithography (NIL) technique and self-assembled anodic aluminum oxide (AAO) template. The length of polymeric nanowires can be adjusted by the duration of thermal NIL, and the fill mechanism of thermoplastic intermediate polymer stamp (IPS) into AAO nanopores is essential for the preparation of SERS-active substrates. The approach shows potential for expanding the use of thermal NIL technique and AAO template for fabricating various nanomaterials, especially flexible and transparent polymer-based nanomaterials.

Summary: We introduce a high-throughput method for generating lanthanide-doped upconversion nanoparticle (UCNP) arrays using polymer pen lithography (PPL). Instead of expensive materials, two types of polymers are employed, with one serving as the ink carrier and the other as the chelator for successful patterning of metal ions. The coordination between the chelator polymer and rare earth ions allows for good ink mobility. Additionally, small molecules with functional groups can also serve as chelators, expanding the ink library for PPL.

Summary: Photodynamic therapy (PDT) is a promising local treatment modality in cancer therapy, but its therapeutic efficacy is restricted by ineffective delivery of photosensitizers and tumor hypoxia. In this study, a phototactic Chlorella-based near-infrared (NIR) driven green affording-oxygen microrobot system was developed for enhanced PDT. The system exhibited desirable phototaxis and continuous oxygen generation, leading to the inhibition of tumor growth in mice. This study demonstrates the potential of using a light-driven green affording-oxygen microrobot to enhance photodynamic therapy.
