microdiscs

Microdiscs are small, disc-shaped structures that have gained attention in various scientific fields, particularly in optics and biotechnology. These structures are typically fabricated from materials such as polymers or glass and are characterized by their extremely small size, often on the order of micrometers or even nanometers in diameter. Their defining feature is their planar, circular geometry, which allows for unique light-matter interactions.

In optics, microdiscs are utilized as optical resonators. Their small size and high refractive index contrast with the surrounding medium can lead to strong confinement of light within the disc. This confinement allows for the creation of whispering gallery modes, where light circulates around the edge of the disc with very little loss. This property makes them useful for applications such as filters, lasers, and sensors. Changes in the environment surrounding the microdisc, such as the presence of specific molecules, can alter the optical properties, enabling detection.

Beyond optics, microdisc structures are also explored in biomedical applications. Their biocompatible nature and surface area make them potential candidates for drug delivery systems or as scaffolds for tissue engineering. The ability to precisely control their size and shape allows for tailored interactions with biological systems. Research continues to explore the diverse potential of microdiscs across various scientific disciplines.
