“…With the synergy of microfluidic technology, rapid manipulation of 50 nm gold nanoparticles in a high-speed flow stream (e.g., 450 μm/s) was explored [122], showing the future potentials of optical force-based silicon nanophotonics in handling biological particles for high-throughput applications. Moreover, on-chip-integrated Laguerre-Gaussian and Bessel beams [123,124] or the interaction of light with nonuniform fluids to realize tunable and reconfigurable optical forces [125] offer new approaches in bioparticle manipulation. Recently, Hu et al integrated acoustic force with optical force in a single optofluidic chip to achieve a precise and specific leukocyte separation, which uses acoustic force to separate granulocytes based on size and optical force to separate lymphocytes and monocytes based on refractive index differences, showing a greater potential of hybrid systems in biomedical applications [126].…”

Light-matter interactions have been explored for more than 40 years to achieve physical modulation of nanostructures or the manipulation of nanoparticle/biomolecule. Silicon photonics is a mature technology with standard fabrication techniques to fabricate micro- and nano-sized structures with a wide range of material properties (silicon oxides, silicon nitrides, p- and n-doping, etc.), high dielectric properties, high integration compatibility, and high biocompatibilities. Owing to these superior characteristics, silicon photonics is a promising approach to demonstrate optical force-based integrated devices and systems for practical applications. In this paper, we provide an overview of optical force in silicon nanophotonic and optomechanical systems and their latest technological development. First, we discuss various types of optical forces in light-matter interactions from particles or nanostructures. We then present particle manipulation in silicon nanophotonics and highlight its applications in biological and biomedical fields. Next, we discuss nanostructure mechanical modulation in silicon optomechanical devices, presenting their applications in photonic network, quantum physics, phonon manipulation, physical sensors, etc. Finally, we discuss the future perspective of optical force-based integrated silicon photonics.

“…The operation of optofluidic prisms is based on droplet manipulation, which can be achieved via different principles, such as molecular diffusion, heat conduction, centrifugation effect, light–matter interaction, and electrowetting‐on‐dielectric (EWOD). [ 21 ] EWOD‐driven prisms are most suitable for solar indoor lighting applications due to the fast response. EWOD is the phenomenon that the contact angle of a droplet on a dielectric surface changes when voltage is applied, as shown in Figure 3 (a,b).…”

Indoor lighting system incorporating daylighting effectively provides potential energy savings as well as meaningful spatial and temporal variation in illuminance beneficial to human well‐being and performance. Integration of the tunable liquid prisms driven by optofluidic technologies further improves the solar indoor lighting systems to achieve better illumination performance and higher solar energy utilization efficiency. Herein, an overview of the state‐of‐the‐art investigations over different aspects of the solar indoor lighting system enhanced by optofluidic liquid prisms, including 1) theoretical background, design, fabrication, and operation of liquid prisms; 2) advances in solar collectors and solar trackers; and 3) major tools for indoor lighting simulation and ray‐tracing simulation, is provided. These studies form a solid foundation for the future solar indoor lighting systems integrated with optofluidic technologies. The prospective study focuses on laboratory and on‐site testing of the integrated system.

“…Therefore, fabricating thin sensing films with a sensor layer composed of ordered microstructures is very attractive [ 19 , 20 ]. Optofluidics is the combination of optics and microfluidics [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ], providing lots of unique advantages for simplifying the micro-electromechanical systems, as well as enhancing their performance [ 30 , 31 ]. Great interest has been drawn to the integration of DO sensors into microfluidic devices.…”

Continuous measurement of dissolved oxygen (DO) is essential for water quality monitoring and biomedical applications. Here, a phosphorescence quenching-based intelligent dissolved oxygen sensor on an optofluidic platform for continuous measurement of dissolved oxygen is presented. A high sensitivity dissolved oxygen-sensing membrane was prepared by coating the phosphorescence indicator of platinum(II) meso-tetrakis(pentafluorophenyl)porphyrin (PtTFPP) on the surface of the microfluidic channels composed of polydimethylsiloxane (PDMS) microstructure arrays. Then, oxygen could be determined by its quenching effect on the phosphorescence, according to Stern–Volmer model. The intelligent sensor abandons complicated optical or electrical design and uses a photomultiplier (PMT) counter in cooperation with a mobile phone application program to measure phosphorescence intensity, so as to realize continuous, intelligent and real-time dissolved oxygen analysis. Owing to the combination of the microfluidic-based highly sensitive oxygen sensing membrane with a reliable phosphorescent intensity detection module, the intelligent sensor achieves a low limit of detection (LOD) of 0.01 mg/L, a high sensitivity of 16.9 and a short response time (22 s). Different natural water samples were successfully analyzed using the intelligent sensor, and results demonstrated that the sensor features a high accuracy. The sensor combines the oxygen sensing mechanism with optofluidics and electronics, providing a miniaturized and intelligent detection platform for practical oxygen analysis in different application fields.
