The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Tweezers with a twist (2011, methodology): “In a similar configuration (using a high-numerical-aperture microscope for optical trapping), Galajda and Ormos trapped shaped objects fabricated through two-photon polymerizatio”
Multiphoton polymerization of hybrid materials (2010, methodology): “The technique has been implemented with a variety of acrylate and epoxy materials, and several components and devices have been fabricated such as photonic crystal templates [5], mechanical devices [6] and microscopic models [7].”
Atoms in complex twisted light (2018, background): “Other developments involving the application of twisted light include micro-manipulation [77]; quantum communications and cryptography [78, 79, 80]”
Force-controllable, optically driven micromachines fabricated by single-step two-photon microstereolithography (2003, methodology): “Although Galajda et al. have also used a two-photon process for making optical rotators in recent years [ 9 ], [11], their rotators are simple wire-frame types and only offer rotary motion with continuous irradiation of light.”
Superpositions of the orbital angular momentum for applications in quantum experiments (2001, background): “The possibility of using such light fields for driving micromachines, and their application as optical tweezers and optical traps make them possibly useful [2, 3, 4, 5].”
