Description

I. Basic Product Information

  • Product Name: High-Stability Fluorescent Microspheres
  • Product Aliases: Nanofluorescent Beads, Fluorescent Nanospheres
  • Product Grade: Research Grade

    Nanofluorescent beads (fluorescent microspheres) are spherical particles that uniformly encapsulate fluorescent dyes (or quantum dots, etc.) in polymer (such as polystyrene) or silica matrices. They range in size from the nanometer scale (typically 10nm to several micrometers) and possess stable fluorescent properties and excellent dispersibility.
