“…Graded-index fiber can also achieve the non-contact capture and manipulation of objects. Developing adjustable OFTs can improve the operating ability and range of applications, which is conductive to its application of optical tweezers in more fields [44,64]. For example, the combination of OFTs and microfluidics can realize the adjustable working distance of optical tweezers [65,66].…”

Optical trapping is widely used in different areas, ranging from biomedical applications, to physics and material sciences. In recent years, optical fiber tweezers have attracted significant attention in the field of optical trapping due to their flexible manipulation, compact structure, and easy fabrication. As a versatile tool for optical trapping and manipulation, optical fiber tweezers can be used to trap, manipulate, arrange, and assemble tiny objects. Here, we review the optical fiber tweezers-based trapping and manipulation, including dual fiber tweezers for trapping and manipulation, single fiber tweezers for trapping and single cell analysis, optical fiber tweezers for cell assembly, structured optical fiber for enhanced trapping and manipulation, subwavelength optical fiber wire for evanescent fields-based trapping and delivery, and photothermal trapping, assembly, and manipulation.

“…V(t) is the trapped atom velocity in the resultant force direction. The combination of those four vector forces is the resultant force, which is normally within the range of pico to nano Newton [36][37][38], which is large enough to trap the nano-scale particle, for instance, gold, silver or biocells. In this proposed device, the required atoms can be trapped and dragged by the WGM probe.…”

The drug delivery and targeting method of gold tourmaline composite atoms generated by optical tweezers in a micro-optical device system is proposed. Gold atoms can be trapped and mixed into the tourmaline content, from which the composite gold tourmaline atoms can be formed using the optical tweezers, which can be delivered close to the desired target cells for cells healing and enhancing applications. In simulation, the optical tweezers are formed by whispering gallery (leaky) modes of light can be generated within a modified add-drop filter, which is known as a Panda ring resonator. It is a nonlinear micro optical device, from which the optical probes called optical tweezers can be generated and used for atom trapping, removing and transportation. In this paper, the optical tweezers are designed for gold tourmaline composite atom trapping, in which the trapped gold tourmaline atoms can be deposited (removed) on (from) the surface for cosmetics and cells enhancing treatment usages. The advantage of the proposed scheme is that the applied (removed) atoms to (from) the surface treatments by the designed trapping and storage device, where the device controlled switching is the key function. In application, the composite trapped gold-tourmaline atoms can be stored with the storage device. In addition, the removal trapped gold-tourmaline atoms can be removed from the treatment surface, from which the used gold atoms can be possible extracted and reused. The cells enhancing and healing applications using the tourmaline properties such as magnetic and far infrared are also plausible.

“…In optical tweezers, temperature-dependent trap stiffness was characterized by correcting the viscosity coefficient of a background medium over certain temperature range [6]. Under irradiation of ultrasonic standing waves, a method for regulating temperature inside a microfluidic chip was also proposed to elucidate the relation between temperature increase and input voltage to transducer along with its manipulation time [7].…”
