A research team from Griffith University developed a technique that uses condensation to noninvasively refill liquid marbles with water. The method could improve the viability of applications such as drug delivery. According to the researchers, it could also establish improved opportunities for the droplet-size microreactors to see use in opto- and microfluidics. “Liquid marbles are droplets of solution that wrap in a thin layer of microparticles that can be used for a large number of biological, chemical, and biochemical applications,” said Nam-Trung Nguyen, co-author of...Read full article

    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:...
    optofluidics
    Optofluidics is an interdisciplinary field that combines principles from optics and fluidics to create devices and systems that integrate the manipulation of light and fluids. This field focuses on the interaction between light and fluidic materials, allowing for the development of innovative technologies with applications in areas such as sensing, imaging, and biotechnology. Key aspects of optofluidics include: Integration of optics and fluidics: Optofluidic devices are designed to...
    hydrophobic
    Hydrophobic is a term used to describe substances or materials that repel or do not readily interact with water. The word hydrophobic comes from the Greek words "hydro," meaning water, and "phobos," meaning fear. Hydrophobic substances typically have nonpolar molecules or regions in their structure, which means there is an even distribution of charge. Water is a polar molecule, with oxygen attracting electrons more strongly than hydrogen. Hydrophobic substances are often nonpolar or have...
    photochemical
    The term photochemical pertains to chemical processes or reactions that are initiated or influenced by the absorption of light. Photochemical reactions involve the interaction of light, often in the form of ultraviolet or visible radiation, with molecules, leading to changes in their chemical structure or properties. These reactions are distinct from thermal or non-light-induced chemical reactions. Key characteristics of photochemical reactions include: Light absorption: Photochemical...
    structural color
    Structural color refers to coloration in materials that is not caused by pigments or dyes but is instead a result of the physical structure of the material. In structural color, the interaction of light with the microscopic or nanoscopic structure of the material produces color through interference, diffraction, or other optical effects. This is in contrast to pigments, which achieve color by selectively absorbing certain wavelengths of light. Key characteristics of structural color...
