Microfluidic Platform Performs Screens of Perovskite Nanocrystals

Facebook X LinkedIn Email
An automated microfluidic technology has been developed containing a spectrographic monitoring module that collects both fluorescent and absorption data. The module moves along the microfluidic channel, collecting data along the way. The technology is capable of collecting 30,000 unique samples per day in both single and multi-phase flow formats. Researchers believe that the technology could expedite the discovery, screening and optimization of colloidal semiconductor nanocrystals, such as perovskite quantum dots, by two orders of magnitude. Additionally, use of the technology revealed that...Read full article

    Glossary
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    perovskite
    The term perovskite refers to a specific crystal structure commonly found in various materials. Perovskite structures have a cubic arrangement of oxygen ions, forming a framework within which other cations (positively charged ions) are located. This crystal structure was named after the mineral perovskite, which has the chemical formula CaTiO3 and was first discovered in the Ural Mountains of Russia. The general formula for the perovskite structure is ABX3, where: A represents a larger...
    microfluidics
    Microfluidics is a multidisciplinary field that involves the manipulation and control of very small fluid volumes, typically in the microliter (10-6 liters) to picoliter (10-12 liters) range, within channels or devices with dimensions on the microscale. It integrates principles from physics, chemistry, engineering, and biotechnology to design and fabricate systems that handle and analyze fluids at the micro level. Key features and aspects of microfluidics include: Miniaturization:...
    quantum dots
    A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
