“…Photonic crystals-materials with a periodic refractive index modulated at the micro- [ 104 ] or nanoscale [ 105 ]-can also be fabricated using photonic nanojets. Specifically, polymeric 2D photonic crystals with a selectable lattice and, hence, optical properties can be prepared by combining multiple UV exposures with oblique and off-axis illuminations [ 106 ]. In this case, patterns typically consist of periodic nanoholes surrounded by a photoresist.…”

Nanostructured surfaces and devices offer astounding possibilities for biomedical research, including cellular and molecular biology, diagnostics, and therapeutics. However, the wide implementation of these systems is currently limited by the lack of cost-effective and easy-to-use nanopatterning tools. A promising solution is to use optical methods based on photonic nanojets, namely, needle-like beams featuring a nanometric width. In this review, we survey the physics, engineering strategies, and recent implementations of photonic nanojets for high-throughput generation of arbitrary nanopatterns, along with applications in optics, electronics, mechanics, and biosensing. An outlook of the potential impact of nanopatterning technologies based on photonic nanojets in several relevant biomedical areas is also provided.

“…Off-axis illumination of periodic sphere array. Another method to increase the pattern complexity is through off-axis illumination of the assembled sphere array [163][164][165][166][167]. In this configuration the incident light is at an angle, resulting in a lateral shift of the photonic nanojet focus.…”

The advance of nanotechnology is firmly rooted in the development of cost-effective, versatile, and easily accessible nanofabrication techniques. The ability to pattern complex two-dimensional and three-dimensional nanostructured materials are particularly desirable, since they can have novel physical properties that are not found in bulk materials. This review article will report recent progress in utilizing self-assembly of colloidal particles for nanolithography. In these techniques, the near-field interactions of light and colloids are the sole mechanisms employed to generate the intensity distributions for patterning. Based on both ‘bottom-up’ self-assembly and ‘top-down’ lithography approaches, these processes are highly versatile and can take advantage of a number of optical effects, allowing the complex 3D nanostructures to be patterned using single exposures. There are several key advantages including low equipment cost, facile structure design, and patterning scalability, which will be discussed in detail. We will outline the underlying optical effects, review the geometries that can be fabricated, discuss key limitations, and highlight potential applications in nanophotonics, optoelectronic devices, and nanoarchitectured materials.
