PhosphorDotsTM: Our phosphor-based nanomaterials can be used in a variety of applications from lighting to solar, and are particularly suited to biomedical applications:
  • Microscopy and multiplexed histology
  • Flow-cytometry
  • Drug delivery
  • Photodynamic therapy
  • In vivo whole animal and clinical imaging (e.g., angiography)
  • Tissue mapping and demarcation (e.g., sentinel lymph node)
  • Real time detection of intracellular events, signaling, and bio-sensing
  • Tracking cell migration (e.g., stem cells)
  • Low cost but sensitive point-of-care detection (e.g., lateral flow)
  • Environment and bio-defense

Old-Fashioned Quantum Dots Sun Innovation's Phosphor DotsTM
Toxicity Toxic without external shell protection through gradual releasing of cadmium or lead. Could be toxic for long-term applications even being insulated by a shell. Has no cadmium, lead, or mercury
Lifetime & durability Shell layer required to protect core from oxidization and emission quenching, increasing cost and manufacturing complexity No risk of oxidization since Phosphor DotsTM are an oxide, and have high emission yield without requiring complex surface treatments. Less manufacturing steps reduces number of steps in which variation, manufacturing tolerances, or defects can occur.
Solubility Solubility in water is generally bad without additional chemical modifications to render a hydrophilic surface. Most biological applications are in aqueous system. Prepared in aqueous solution, so solubility is not a problem.
Size vs. Color Emission color is size dependent. Color is not size dependent. Particle size can be tailored for different biological applications with same detection technology.
UV absorption Broad UV absorption. Tunable colors emission from 400 nm to 900 nm. Narrow UV absorption.
Excitation Simultaneous excitation due to broad UV excitation Simultaneous excitation due to same host UV absorption.
Synthesis Synthesis is complicated, such that scaling up production could be difficult. Simpler synthesis which can be easily scaled up to mass production.
Functioning More steps such as ligand exchange are required to add functional groups. No ligand exchange required; easy to add functionalization.
