We provide a broadband channeled, modulated full polarization imaging technology based on dispersion-compensation Savart plates in 2020. It has the advantages of being compact, using the snapshot method, and having a bandwidth of 0.132 µm. It is thus invaluable for applications in diverse fields, including remote sensing, biomedicine, and military science. However, there are a lot of angle restrictions in the system. In practice, these angles cannot achieve such high machining precision, and we use the tolerance or compensation method of errors to analyze the influence of the angle deviation. This analysis will help the system achieve better compactness and stability and provide analysis methods for systems that use crystals as its key elements.

Optical metasurfaces, arrays of nanostructures engineered to manipulate light, have emerged as a transformative technology in both research and industry due to their compact design and exceptional light control capabilities. Their strong light-matter interactions enable precise wavefront modulation, polarization control, and significant near-field enhancements. These unique properties have recently driven their application in biomedical fields.

The spin angular momentum (SAM) plays a significant role in light-matter interactions. It is well known that light carrying SAM can exert optical torques on micro-objects and drive rotations, but 3D rotation around an arbitrary axis remains challenging. Here, we demonstrate full control of the 3D optical torque acting on a trapped microparticle by tailoring the vectorial SAM transfer.

Recent studies demonstrated that glucagon-like peptide-1 receptor agonists (GLP-1RA) have promising prospects in promoting wound healing. In this study, we intend to investigate the pro-healing effect and potential molecular mechanism of topical administration of GLP-1RA liraglutide on wounds in normoglycemic mice. Two full-thickness wounds were created on the back of the C57BL/6 mice.

We present a novel photoreconfigurable metasurface designed for independent and efficient control of electromagnetic waves with identical incident polarization and frequency across the entire spatial domain. The proposed metasurface features a three-layer architecture: a top layer incorporating a gold circular split ring resonator (CSRR) filled with perovskite material and dual -shaped perovskite resonators; a middle layer of polyimide dielectric; and a bottom layer comprising a perovskite substrate with an oppositely oriented circular split ring resonator filled with gold. By modulating the intensity of a laser beam, we achieve autonomous manipulation of incident circularly polarized terahertz waves in both transmission and reflection modes.

Macrophage (Mph) polarization and functional activity play an important role in the development of inflammatory lung conditions. The previously widely used bimodal classification of Mph into M1 and M2 does not adequately reflect the full range of changes in polarization and functional diversity observed in Mph in response to various stimuli and disease states. Here, we have developed a model for the direct assessment of Mph from bronchial alveolar lavage fluid (BALF) functional alterations, in terms of phagocytosis activity, depending on external stimuli, such as exposure to a range of bacteria (, and ).
