“…From these publications one can see that, in the case of relatively small magnifications 1.5 3 M = − , as those reported e.g. in [95,109,120,121,123,124,126,130,134,142], the solid immersion lens and the spherical particle produce very similar effects. On the contrary, in the range of magnification values 3 6 M = − the difference between a sphere and a SIL becomes pronounced, as reported e.g.…”

Materials with relatively small refractive indices (2 n <), such as glass, quartz, polymers, some ceramics, etc., are the basic materials in most optical components (lenses, optical fibres, etc.). In this review, we present some of the phenomena and possible applications arising from the interaction of light with particles with a refractive index less than 2. The vast majority of the physics involved can be described with the help of the exact, analytical solution of Maxwell's equations for spherical particles (so called Mie theory). We also discuss some other particle geometries (spheroidal, cubic, etc.) and different particle configurations (isolated or interacting) and draw an overview of the possible applications of such materials, in connection with field enhancement and super resolution nanoscopy.

“…In this case, it is a semi-immersed imaging system and the ethanol can pick up more high-frequency information. In our previous research, we find that the immersion medium can work as a lens and form super-resolution images [23]. No images can be formed with the BTG microsphere when observing the small object at d¼ 2.9 μm as shown in Fig.…”

“…Due to the different imaging effects that can be produced when utilizing microspheres of different materials in combination with different media, a growing number of researchers are focusing their attention on the study of media microspheres. For example, in 2015, Yonghong Ye et al [ 31 ] used experiments to demonstrate that sharper images can be obtained when microspheres are half-submerged in the medium. On that basis, in 2022, Jianguo Wang et al [ 20 ] from Nanjing Normal University partially immersed PS microspheres in water, spin-on-glass, SU-8 resist, and S1805 resist.…”

Conventional optical microscopes are only able to resolve objects down to a size of approximately 200 nm due to optical diffraction limits. The rapid development of nanotechnology has increased the demand for greater imaging resolution, with a need to break through those diffraction limits. Among super-resolution techniques, microsphere imaging has emerged as a strong contender, offering low cost, simple operation, and high resolution, especially in the fields of nanodevices, biomedicine, and semiconductors. However, this technology is still in its infancy, with an inadequate understanding of the underlying principles and the technology’s limited field of view. This paper comprehensively summarizes the status of current research, the advantages and disadvantages of the basic principles and methods of microsphere imaging, the materials and preparation processes, microsphere manipulation methods, and applications. The paper also summarizes future development trends.
