Quantum dots (QDs) are recognized as the most promising functional nanotechnology, for which its discoverers are awarded the Nobel Prize in 2023. Their remarkable tunability of optoelectronic properties has attracted significant interest from both researchers and industries, placing QDs at the forefront of developing cutting‐edge technologies. This comprehensive review aims to explore the exciting results in terms of fundamental science, present and forthcoming applications. Beyond their contributions to biomedicine, energy, environmental science, quantum sensing, and quantum information processing, QDs have brought important results due to their integration into micro/nanorobotic systems, self‐propelled materials representing the state of the art research at the micro and nanoscale. These hybrid systems have demonstrated noteworthy outcomes, unlocking novel possibilities in biomedicine, quantum sensing, and environmental science, accurately reviewed in this article. In conclusion, this review addresses current challenges, offering insights to facilitate further research, stimulate new developments, and enhance the comprehension of the full potential of QDs.

“…Additionally, they can provide diluted magnetic properties [14], half-metallic behavior [15,16], quantum dots [17], and nanocrystal cores [18]. A study conducted by P. Maity et al [19] reported that CdS diluted magnetic semiconductor quantum dots can be considered a promising optoelectronic as well as magnetic material, which can be employed as an active material for prolonged use in quantum opto-spintronics with tunable efficiency. S. Suresh studied the dielectric properties of CdS nanoparticles [20].…”

CdS nanoparticles doped with Mn were synthesized by chemical precipitation using varying concentrations of Mn at Cd1-xMnxS, where (x) = 0.00, 0.03, 0.05, and 0.07. The samples were examined using scanning electron microscopy (SEM), energy dispersive X-ray techniques (EDX), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, dielectric properties, and AC conductivity measurements. SEM micrograph shows that pure CdS nanomaterial has agglomerates primarily composed of nanoparticles, whereas the sample with a concentration of 0.03 contains smaller particles. In response to the phonon confinement effect, The Raman spectra of CdS nanoparticles exhibited peaks at 303 cm−1 and 603 cm−1. In contrast, the Raman spectra of Mn:CdS nanocomposites displayed a prominent fundamental mode at 301 cm−1 and a less pronounced overtone mode at 601 cm−1. The dielectric properties and the AC conductivity of CdS have been investigated over a wide frequency range of 0.1 Hz to 10 MHz and at a variety of temperatures ranging from 298 to 423K. The real and imaginary parts of the complex dielectric constant (εʹ, εʹʹ), the electric modulus, and AC conductivity of CdS were found to depend on Mn content at different temperatures.
