    Area of Science:

    • Cellular biology
    • Biotechnology
    • Molecular imaging

    Background:

    • Bioluminescence imaging (BLI) is emerging as a key technique in live-cell analysis, offering an alternative to fluorescence imaging.
    • While fluorescent probes offer higher resolution, BLI provides superior signal-to-noise ratios due to negligible background and minimal cellular toxicity.
    • This makes BLI particularly advantageous for long-term cellular studies and detecting low-abundance molecules or interactions.

    Discussion:

    • Diverse luciferases from various species enable a wide range of BLI applications, including in vivo cell tracking, protein-protein interaction studies, and monitoring signaling pathways.
    • Optimizing BLI involves advancements in luciferase brightness and color, enhanced microscope optics, and ultrasensitive, low-noise camera technology.
    • The review covers the fundamental differences between bioluminescence and fluorescence, practical applications in cellular imaging, and available tools.
