Summary: We have demonstrated a platform for optical evanescent vortex by focusing a laser beam with orbital angular momentum onto a one-dimensional photonic crystal. This platform can trap and manipulate different micro-scale specimens simultaneously, relying on the low-loss Bloch surface waves on the dielectric 1DPC. The use of these waves allows for the induction of rotation or orbital motion in the specimens, providing a new mechanism for optical force manipulation.

Summary: Automated manipulation of small particles using external fields is an emerging technique widely used in different areas. Existing reduced-order physical models for particle manipulation are limited to highly idealized settings and do not account for complex nonlinear processes. In this study, the authors propose a data-driven architecture based on hydrodynamic manipulation and artificial neural networks to achieve precise and flexible control of particles in microfluidic systems. They successfully demonstrate various advanced manipulations, revolutionizing automated particle manipulation and showcasing the potential of data-driven approaches in improving microfluidic technologies.

Summary: Researchers have developed a new active system that allows for the free rotation of micro-rotors while observing the interplay of rotation and translation. Using a non-tweezing circularly polarized beam, they were able to rotate hundreds of birefringent colloids and observe the orbiting of neighboring particles with different angular velocities. They also derived an analytical model to explain the observed dynamics.

Summary: This study presents the first investigation on the ultrafast dynamics and reconfigurability of polarization in freestanding films of a typical relaxor ferroelectric using femtosecond-resolution electron-scattering techniques. The results demonstrate that femtosecond light pulses can induce changes in both the magnitude and direction of the polarization vector within polar nanodomains on a picosecond time scale. These findings offer new possibilities for dynamically reconfigurable control of polarization in nanoscale relaxor ferroelectrics.

Summary: Traditional grating lenses can adjust wavefronts through phase accumulation, while plasmonic resonances in metasurfaces can be used for optical field modulation. Diffractive and plasma optics have developed in parallel, offering easy processing, small size, and dynamic control advantages. Structural design can combine the advantages of both, showing great potential value.

Summary: This study investigates the bound states in the continuum (BICs) and light trapping characteristics of quasi-BICs based on PCM GSST. By perturbing the symmetry of the structure, an ideal BIC is transformed into a high-Q-factor quasi-BIC. The average field-enhancement factor (EF) of the quasi-BIC is evaluated, and the effects of structure parameters, polarization angle, and incident angle on EF are discussed. Furthermore, the switching characteristic of light trapping of quasi-BICs is analyzed. The research provides insights into the realization of high-Q-factor metasurfaces and actively tunable and reconfigurable micro or nano optical devices.

Summary: This study demonstrates the three-dimensional optical trapping and manipulation of irregular hexogen (RDX) particles in a liquid environment using annular core fiber tweezers. By assembling a high-refractive-index glass microsphere on the facet of the fiber, a converging light field with a large-angle focus is obtained. The proposed optical fiber tweezers have the advantages of low cost, simple manufacturing, and large trapping stiffness.

Summary: Macrophages play a crucial role in zebrafish cardiac regeneration by activating the epicardium and inducing cardiomyocyte proliferation. They are specifically recruited to the epicardial-myocardial niche, triggering epicardial expansion and upregulating vegfaa expression. This, in turn, enhances endocardial notch signaling and promotes cardiac growth.
