Fluorescent probes offer sharper view of plant tissues

Researchers at the Indian Institute of Technology Gandhinagar (IITGN) and the Regional Centre for Biotechnology, Faridabad, have developed and tested a new class of fluorescent probes that enable scientists to visualize xylem, the specialized tissue responsible for transporting water and minerals through plants. The work, published in Plant and Cell Physiolo

The top 3

  1. Pioneers of Fluorescence Microscopy: Fredrick W. Herschel first observed fluorescence in 1845, with Sir George G. Stokes further studying the phenomenon; Carl Zeiss and Carl Reichert later developed these observations into fluorescence microscopy in the early 1900s, and Oskar Heimstaedt created the first working fluorescent microscope in 1911.
  2. Highest Resolution Microscopy Techniques: Electron microscopy (EM) provides the highest resolution for cellular ultrastructure, capable of visualizing single atoms, while super-resolution light microscopy techniques like STED, PALM/STORM, and MINFLUX overcome the diffraction limit to offer significantly enhanced resolution for live biological samples.
  3. Top Applications of Biological Imaging: Biological imaging is crucial for drug discovery, studying disease pathology like cancer progression, and evaluating gene therapies, while also being extensively used to examine normal anatomy and physiology, enabling real-time observation of biological processes at various scales.
