Ideal optical imaging relies upon the high-quality focusing of excitation light and accurate detection of the emission light from the fluorescent sample. However, both the optics in the microscope and the biological samples being investigated can introduce aberrations, thus causing degradation in resolution, loss of fluorescent photons, and deterioration of signal-to-background-ratio (SBR), etc. Moreover, microscopes with high numerical apertures (NA), especially the super-resolution microscopy, are more sensitive to aberrations, because the high-NA objectives are more susceptible to high-order aberrations. To detect and correct these optical aberrations, a large number of adaptive optics (AO) technologies have been explored in the last two decades. Conventional AO leverages specific devices, such as the Shack-Hartmann wavefront sensor to measure and correct optical aberrations, then utilized wavefront corrective devices such as spatial light modulators (SLMs) to compensate for the measured aberrations by reshaping the wavefronts. However, conventional AO complicates the optics, imaging procedures, and computation, resulting in many limitations in the actual imaging process.

Vortex is one of the most common phenomena in nature. In 1992, Allen et al. proposed that such vortex beams carry orbital angular momentum (OAM), which has furthered the development of vortex beams in various fields, including optical tweezer, quantum communication and bio-image.

Spotlight on Optics
Metasurfaces, which consist of tailor-made two-dimensional arrays of resonant structures, are promising for achieving planar and compact optical devices capable of shaping optical waves. Their performance is based on the design of the scattering phase of the individual resonant structures. While a variety of functions, such as optical vortex generation or focusing, have been reported separately, finding designs allowing the integration of multiple functions on a single metasurface is needed. This will further stimulate the development of metasurfaces for practical applications in high-speed data communication.

Pulsed Laser Ablation in Liquid (PLAL) is a cutting-edge technique for nanoparticle synthesis. The technique can be understood as the irradiation with a laser source of a material immersed in a liquid. The versatility of the technique due to the possibility to change the liquid and irradiated material represents a critical advantage. Besides, the nanoparticles can also be tailored by adding specific ions and dopants, allowing precise control over the nanoparticles' composition and surface chemistry. This control is essential for catalysis, or nanomedicine applications where purity, composition, and nanoparticle surface groups directly influence the performance.
