Discovery of Quantum Dots in Stained Glass Window Making
The 2023 Nobel Prize for Chemistry was awarded for the discovery of quantum dots, which have been used in stained glass window making for over a thousand years. These tiny particles emit light of different colors when light is fired into them, depending on their size. Scientists found similar properties in ancient glass from the 10th century, containing tiny bits of gold and silver that enhance red and yellow light, resembling the behavior of quantum dots.
Application of Quantum Dots in TV Technology
Quantum dots have revolutionized TV technology by enhancing color displays. Used in LED TVs, quantum dots emit a wide range of colors when light shines through them, creating more vibrant and diverse color spectrums than traditional LED screens. By adjusting the size of the quantum dots, different colors can be emitted, leading to improved visual experiences for viewers.
Potential Medical Applications of Quantum Dots
In addition to TV technology, quantum dots hold promise in the field of medicine for diagnostics. Their ability to emit different colors can aid in identifying specific areas in the body for medical imaging and diagnosis. This advancement could lead to more precise and targeted medical treatments through the use of nanotechnology.
Nanotechnology for Cancer Treatment
Nano shells made of gold and silver can be injected into tumors, then heated up with red light to kill cancer cells. Experiments on raw chicken are being done, aiming to transition to human trials. The concept has potential for targeted cancer treatment.
Origins of Nanotechnology and Nobel Prize
The origins of quantum dots and nanotechnology trace back to the Soviet Union in 1981, where Ekimov and Louis Bruce independently worked on similar research. A third Nobel laureate, Moongi Balwede, faced initial failure in chemistry but persevered, highlighting the importance of resilience and determination in scientific pursuits.
