Using Perovskites to Produce Light-Emitting Quantum Dots

In the worldwide pursuit for creating practical computing and communications devices based on quantum principles, one prospectively useful component has been unachievable: a source of light containing individual particles that is ideally predictable, constant, and with steady characteristics.

Using Quantum Dots for Tracking Fate of Individual Pollen Grains from Flowers

At Stellenbosch University, a pollination biologist has been using quantum dots to track the destiny of individual pollen grains. This is proving to be pathbreaking in an area of research that has been affected by the lack of a universal technique for tracking pollen for more than a century.

New Scalable, Cost-Effective Approach to Synthesize TMD Quantum Dots

Two-dimensional (2D) transition metal dichalcogenides (TMDs) nanomaterials like molybdenite (MoS2), with a structure similar to graphene, have been accepted as futuristic materials for their broad array of potential applications in sensors, biomedicine, photodetectors, catalysts, and energy storage devices.

Study Shows Strained Colloidal Quantum Dots Could be Viable Alternatives to Nano-Scale Light Sources

Deliberate “squashing” of colloidal quantum dots when a chemical synthesis is in progress could lead to the creation of dots with the capability of stable, “blink-free” light emission that is on par with the light generated by dots formed using highly complex processes.

New Quantum Dots Improve Cell Imaging

A team of scientists from the University of Illinois at Urbana-Champaign and Mayo Clinic have designed a unique type of molecular probe that can measure and count RNA in cells and tissue without organic dyes. The probe is based on the conventional fluorescence in situ hybridization (FISH) method, but it depends on compact quantum dots to illuminate molecules and diseased cells instead of fluorescent dyes.
