Fluorescence Applications in Cell Culture Detection
Application Areas: Medical Testing, Disease Prevention, Biological Research, Educational Research
Hospital routine fluorescence detection for fungi, gynecology, and other applications provides important evidence for clinical diagnosis. High-demand detection requirements from universities, research institutes for scientific research, and hospital cancer verification require more precise imaging equipment support. Macroscopic fluorescence observation for biological cell temporal sequences provides key technical means for cell biology research.
Technical Principles:
Fluorescence is a luminescence phenomenon produced by transitions between energy levels within molecules. When a material (fluorophore) absorbs light of specific wavelengths (typically ultraviolet or blue light), it becomes excited to a high-energy state. When this molecule returns to its ground state, it emits light. The wavelength of emitted light is typically longer than that of absorbed light, meaning the energy of emitted light is usually less than that of absorbed light. This occurs because molecules lose some energy in non-radiative forms after being excited to high-energy states, resulting in emitted light having lower energy than absorbed light. This energy difference is known as the Stokes shift.
Fluorescence Phenomenon Classification:
Autofluorescence: Certain substances naturally possess fluorescence-generating properties, such as certain organic molecules, minerals, or biological organisms. They naturally absorb photons and release energy in the form of fluorescence. However, in biological microscopy, autofluorescence often produces weak signals and low-contrast images, making it undesirable in many cases and potentially hindering observation of fluorescently labeled samples due to autofluorescence background.
Secondary Fluorescence: This involves introducing fluorescent dyes or labels into samples to enhance or induce fluorescence. Secondary fluorescence, especially through fluorescent protein labeling (such as green fluorescent protein GFP) or fluorescent probes (such as quantum dots or organic dyes), is a critical component of modern biological imaging and is widely used in biomedical research.
