Fluorescent dye-doped silica (DDS) nanoparticles have demonstrated an excellent potential as unique tools to design inexpensive sensors, benign environmental tracers and optical probes for a wide variety of applications. AQM develops dye-doped silica nanoparticles using a wide variety of dyes to produce photoluminescence that spans the visible range to near-infrared part of the electromagnetic spectrum. Our DDS protects the dyes thermally and from environmental conditions leading to longer stability and improved performance.
