Biodegradable Luminescent Silicon Quantum Dots for Two Photon Imaging Applications

摘要: Cadmium- and lead-based quantum dots are normally coated for biological applications, because their degradation may result in the release of toxic heavy metal ions. Here, we synthesize silicon that expected to biodegrade non-toxic products. A chitosan coating is used render stable storage conditions biodegradable at physiological conditions. The applications these particles demonstrated cellular imaging with single two-photon excitation. These results open door a new generation have wide variety derived from flexibility chitosan.
