Special Issue Information

Dear Colleagues,

The rapid evolution of nanophotonics has opened new horizons in optical manipulation, enabling capabilities far beyond those of conventional optical tweezers. Nanophotonic platforms, spanning high-Q dielectric metasurfaces, plasmonic nanoantennas, and hybrid photonic architectures have provided powerful strategies for engineering strongly confined electromagnetic fields and tailored momentum transfer at deeply subwavelength scales. These advances have significantly enhanced our ability to control nanoparticles, biomolecules, quantum emitters, and other nanoscale objects with unprecedented precision.

A particularly exciting direction is the integration of nanophotonics with optofluidics, which has catalyzed the emergence of novel nanotweezer paradigms based on field enhancement, thermally mediated forces, and gradient-engineered energy landscapes. Such optofluidic platforms enable low-power and stable trapping, high-throughput particle transport, and robust manipulation within microfluidic environments. They also unlock near-field optical sorting, allowing selective transport and enrichment based on particle size, composition, or optical properties. In addition, enhanced optical chirality in metasurfaces has opened pathways for chiral-selective manipulation, offering unique opportunities in biochemical analysis, enantioselective sensing, and fundamental studies of chiral light–matter interactions.

The convergence of metasurfaces, near-field optical forces, and optofluidic engineering is driving rapid progress across biosensing, soft-matter physics, nanomanufacturing, quantum technology, and lab-on-chip systems. Programmable photonic architectures and AI-assisted inverse design further expand the design space, providing unprecedented flexibility for crafting advanced optical manipulation platforms.

This Special Issue, titled "Nanophotonics and Metasurfaces for Optical Manipulation", invites contributions that advance the fundamental physics, device concepts, experimental techniques, and emerging applications of nanophotonic optical manipulation. We welcome original research articles, review papers, and short communications.

We look forward to receiving your contributions.

Nano-tweezers, especially those based on photonic crystals and plasmonic structures, are powerful tools for trapping, manipulating, or accelerating nano-sized objects. However, the precise control of the inter-distance between trapped nanoparticles has rarely been considered. In this paper, we propose a mirror-symmetric optical conveyor belt, in which each unit contains three graded nano-slots. Through the optimized design of spacing between these nano-slots, the structure generates multiple trapping centers, enabling wavelength-selective control over trapping positions. The results show that, through dynamically shifting excitation wavelengths, the programmable bidirectional optical manipulation of nanoparticles can be achieved. Also, the inter-distance between trapped particles can be tuned with subwavelength precision. The proposed structure provides a versatile solution for lab-on-a-chip systems, especially for systems aiming to study the interactions between objects. Full article

Photonic jets (PJs) generated from mesoscale dielectric particles can achieve sub-diffraction-scale light field constraints and significant near-field intensity enhancement, which have important application value in the fields of nanoimaging, optical sensing, and laser processing. Recent studies show that the axial-extension and transverse-focus characteristics of PJs can be effectively regulated through interface engineering methods, such as using double-layer structures and truncated geometries. Such structures can be referred to as Janus microstructures separated by surface refracted interfaces. However, systematic research on the effect of incident light polarization on the formation and regulation of PJs on the surface interfaces of Janus systems is lacking. In this study, the PJ characteristics under polarization regulation in curved-interface Janus microcylinders are systematically investigated by performing full-wave numerical simulations. The results show that polarization modulation introduces a new degree of freedom for regulating the energy flow distribution and morphology of PJs. An appropriate polarization state can be selected to effectively regulate key characteristic parameters, such as the length, peak intensity, and full width at half maximum of the nanojet, without changing the particle geometry or material composition. This study reveals the synergy between the surface-interface Janus structures and polarization engineering, providing a new physical method for the flexible regulation of PJs in near-field optics.
