“…12c ) 205 , for which the force peaks at the resonance of the object. It has recently been reported that when a plasmonic nanoparticle is half immersed in an inhomogeneous dielectric background, a reversal of the plasmonic binding force occurs near the Fano dip 206 . Thus, the force magnitude can be tuned by changing the permittivity of the background medium.…”

Optical tweezers and associated manipulation tools in the far field have had a major impact on scientific and engineering research by offering precise manipulation of small objects. More recently, the possibility of performing manipulation with surface plasmons has opened opportunities not feasible with conventional far-field optical methods. The use of surface plasmon techniques enables excitation of hotspots much smaller than the free-space wavelength; with this confinement, the plasmonic field facilitates trapping of various nanostructures and materials with higher precision. The successful manipulation of small particles has fostered numerous and expanding applications. In this paper, we review the principles of and developments in plasmonic tweezers techniques, including both nanostructure-assisted platforms and structureless systems. Construction methods and evaluation criteria of the techniques are presented, aiming to provide a guide for the design and optimization of the systems. The most common novel applications of plasmonic tweezers, namely, sorting and transport, sensing and imaging, and especially those in a biological context, are critically discussed. Finally, we consider the future of the development and new potential applications of this technique and discuss prospects for its impact on science.

“…Repulsive optical binding forces have also been predicted theoretically but have yet to be observed experimentally. 71,322,323 Interestingly, phase gradients have also been shown to control the optical binding force, 324−326 while to the best of our knowledge, particle assembly driven by the phase gradient of low-frequency fields has not been reported in the literature.…”

Electromagnetic forces and torques enable many key technologies, including optical tweezers or dielectrophoresis. Interestingly, both techniques rely on the same physical process: the interaction of an oscillating electric field with a particle of matter. This work provides a unified framework to understand this interaction both when considering fields oscillating at low frequencies�dielectrophoresis�and high frequencies�optical tweezers. We draw useful parallels between these two techniques, discuss the different and often unstated assumptions they are based upon, and illustrate key applications in the fields of physical and analytical chemistry, biosensing, and colloidal science.

“…As reversed case, regulation of relative disposition of objects can control optical outputs, such as near field optical binding force, which is considered as an emerging concept for optical manipulation. Mahdy and co‐workers reported possibility of reversal of near field optical binding force using dimer sets of different shaped objects, such as sphere, cube, cylinder, and ring . The force reversal is observable at the situation of symmetry breaking.…”

Soft and flexible two-dimensional (2D) systems, such as liquid interfaces, would have much more potentials in dynamic regulation on nano-macroc onnected functions. In this Minireview article, we focus especially on dynamic motional functions at liquid dynamic interfaces as 2D material systems. Severalr ecent examples are selectedt ob ee xplained for overviewing features and importance of dynamic soft interfaces in aw ide range of action systems. The exemplified research systems are mainly classified into three cate-gories:( i) controlo fm icroobjects with motional regulations; (ii)control of molecular machines with functions of target discriminationa nd optical outputs; (iii)control of living cells including molecular machine functions at cell membranes and cell/biomolecular behaviors at liquid interface. Sciences on soft 2D media with motional freedom and their nanoarchitectonics constructions will have increased importance in future technology in addition to popularr igid solid 2D materials.
