“…In 1980's, Alexei Ekimov documented that these minuscule semiconductor-based particles (1-20 nm) have noteworthy optical properties [54,55]. QDs are commonly composed of a bandgap semiconductor shell surrounding a heavy metal core intended to overcome surface deficiencies and enhance quantum yield [56][57][58]. These core-shell nano particles exhibit high emission brightness, intermittent light emis-sion, and tunable composition and properties making them ideal components for biomedical applications which include imaging, drug delivery, and cancer therapy [58][59][60][61][62][63].…”

“…These features make QDs excellent fluorescent probes for diverse biomedical imaging applications. Due to their nanoscale size, QDs can be utilized to visualize subcellular components from organelles down to individual proteins [56,57,[65][66][67][68]. This is particularly useful regarding its potential application as polychromatic labels for fluorescent-activated cell sorting in which a single laser beam can excite different QD probes that emit different wavelengths [64].…”

Quantum theory diverges from classical physics by identifying discrete states instead of a continuous spectrum. While quantum phenomena have evolved independently from biology, the fields are converging, particularly in medical science. Understanding quantum principles is crucial for advancing medical technologies, as evidenced by the current developments outlined in selected articles from the past decade. Despite decades of existence, the full realization of the benefits of quantum physics has yet to be achieved. Recent technological advances, rooted in quantum principles, include quantum computers, artificial intelligence (AI) quantum algorithms, quantum-based lasers, and nanoparticles. Quantum computing, a potential foundation for robust infrastructures, faces challenges, such as the need for highly controlled conditions and specialized algorithms, prompting researchers to explore possibilities and pitfalls. Hence, optimizing existing AI tools and exploring quantum computing possibilities are priorities. Advances in quantum cascade lasers (QCLs) operating at ambient temperatures and producing hyperspectral images are sought for biomedical applications. Potential breakthroughs in infrared microscopy based on QCL technology could enable the submicron resolutions of molecules. The convergence of quantum physics and biology in medical science is in its early stages. Resolving the challenges in practical quantum technology within its fundamental principles is crucial for future progress.
